Dynamic random-access memory (DRAM) chips contain many other transistors besides the access transistor to enable full operation of the DRAM memory. These peripheral transistors must meet stringent requirements which preclude a ‘copy-paste’ of regular logic transistor process flows.

One critical requirement imposed by present DRAM chip architectures is the ability of the periphery to withstand thermal treatments at 550-600°C and above. While the first part of this article series focused on DRAM basics and peripheral circuits, this part will provide a detailed account of DRAM periphery, explaining different generations of thermally stable peripheral transistor technology ranging from planar high-k/metal-gate transistors to FinFETs.

DRAM periphery: From SiON-based gate stacks to high-k/metal gates

Until 2018, DRAM peripheral transistors were predominantly made in planar logic MOSFET technology with poly-Si/SiO2 or poly-Si/SiON gates. These technologies were less advanced than the transistors used for high-performance logic in order to maintain the DRAM cost-per-bit trendline.

However, an improved technology for the periphery became necessary to keep pace with the performance enhancement enabled by subsequent generations of DRAM memory. The most obvious candidate was moving to a planar transistor architecture with a high-k/metal-gate stack—a transition that occurred as early as 2007 in the high-volume manufacturing of logic technologies.

Since about 2007, imec, together with its partners, has actively explored a DRAM-compatible version of high-k/metal-gate transistors and proposed multiple material and integration options to the memory industry. Today, almost every device with a DRAM memory inside contains a planar peripheral transistor technology with high-k/metal gates, which imec has been pioneering for more than 15 years.

Below is a grasp of some of the proposed material, module, and integration options, all differing in fabrication complexity and performance levels.

High-k/metal-gate integration: Thermally stable gate-first and gate-last integration flows

One of the solutions demonstrated by imec for potential early introduction was based on a gate-first integration approach, in which the metal gate is deposited before the high-temperature source/drain junction activation anneal. Gate stacks for nMOS and pMOS can be optimized separately by using different work function metals and layer thicknesses for the high-k/metal-gate stack (for example, TiN/Mg/TiN for n; TiN for p).

One of the critical parameters is obtaining an effective work function that is low enough for nMOS and high enough for pMOS to ensure a good Ion/Ioff ratio. Researchers achieved this by doping the gate stacks (with different dopants for pMOS and nMOS), which enabled a shift in the threshold voltages.

The choice of the dopant materials and their integration also provided a knob for improving the thermal stability of the gate stack and enabling the different Vth required by the DRAM chip. The DRAM-specific requirement for low gate leakage was addressed, among others, by adopting thicker gate stacks compared to logic-oriented solutions.

Imec also successfully demonstrated a thermally improved version of a gate-last integration approach, also called replacement metal gate (RMG) flow. In a gate-last flow, a poly-Si capped dummy gate is deposited and remains in place until the junction activation anneal is applied. After that, the dummy poly is replaced by the target metal gate.

Optimized source/drain junctions

Source/drain junctions are critical to ensure the functionality of MOSFET transistors. They are formed by creating a dopant gradient in the source/drain areas. As conduction channel lengths continued to shrink, ultra-shallow junctions became indispensable to ensure good electrostatic control over the channel. However, for peripheral transistors, the thermal treatments during DRAM memory anneal trigger an unwanted diffusion of the dopants, requiring more complex process flows to maintain the dopant gradient.

This issue can be addressed by changing the junction implant scheme using, for example, pre-amorphization implants and junction co-implants. Imec demonstrated several sets of optimized junctions suited for various threshold voltage targets.

A thermally stable silicide process

A general challenge for all transistors is to keep the source/drain contact resistance as low as possible. Source/drain contacts are formed by bringing a metal in contact with the source/drain regions, creating a Schottky barrier at the interface.

To ensure low resistance, two techniques are typically applied: (1) heavy doping of the source/drain regions and (2) complete silicidation of the source/drain areas—the silicides being formed through the reaction of the contact metal with the doped Si.

However, Ni(Pt) silicide, traditionally used in logic devices, cannot withstand the DRAM-related anneal temperatures. Imec proposed a thermally stable NiPt-based silicide module with low contact resistance by implementing additional implants and annealing steps for silicide stabilization.

Thermally stable, FinFET-based peripheral platform

Applications like automotive, artificial intelligence (AI) and machine learning (ML) impose increasingly stringent requirements on DRAM memories, driving the need for faster, more reliable and power efficient peripheral transistors. One option is to retrace the path of ‘logic’ and move from planar high-k/metal-gate transistors to FinFETs.

The logic roadmap made this transition as early as 2011 after R&D clearly showed the superior performance of transistors with fin-shaped conduction channels: improved Ion/Ioff, better short channel control, higher drive current at reduced footprint (due to a higher effective width of the channel), and lower power consumption—while keeping cost under control. On top of that, the use of tall fins provides a way to reduce the threshold voltage mismatch, which can particularly benefit the DRAM sense amplifiers.

Just like for the planar versions, the DRAM-specific requirements preclude a copy-paste of FinFET process flows developed for regular logic. In response, imec developed a thermally stable FinFET-based peripheral technology platform with integrated modules optimized for DRAM. Multiple flavors with different performance-cost trade-offs have been proposed to the industry for their next-generation DRAM products.

Thermally stable gate-first and gate-last FinFET integration flows

In 2021, imec reported the first experimental demonstration of a thermally robust integration flow for FinFETs using an optimized gate-first approach for implementing the high-k/metal-gate stack. Compared to a traditional gate-first approach, the modified flow implements gate stacks with the same thickness and the same work function metal for both nMOS and pMOS. So-called Vth shifter materials are then diffused into the high-k dielectric to tune the effective work function of the nMOS and pMOS devices.

This modified gate-first approach reduces the gate asymmetry and enhances the thermal stability of the flow. By using this flow, the researchers demonstrated improved Ion/Ioff and short channel control over planar high-k/metal-gate counterparts. These metrics did not degrade after the DRAM-specific anneal. Flavors with taller fins (with up to 80-nm height) have also been developed, with improved threshold voltage mismatch and area gain.

A drawback of the gate-first integration approach is the relatively high threshold voltage, which originates from the impact of the high-temperature anneal on the gate stack during junction activation. This issue can be solved using a gate-last (or RMG) integration approach, which, however, comes with additional process steps. At IEDM in 2022, imec showed a thermally stable version of a FinFET gate-last flow.

An optimized and thermally stable gate-last FinFET flow with a Mo-based work function metal for pMOS

Typical for a gate-last flow is the use of different work function metals for nMOS and pMOS devices. At VLSI in 2024, imec demonstrated the performance benefits of using a novel Mo-based work function metal for pMOS instead of the conventional TiN-based approach. The new gate stack module was successfully integrated into a gate-last FinFET flow and proven to be thermally stable.

The DRAM-compatible flow with integrated Mo-based p-work function metal yielded sufficiently low Ioff current and low threshold voltage (0.12 V) for the pMOS devices. The FinFETs were also benchmarked against a thermally stable planar high-k/metal-gate reference, showing a three times higher Ion (at target Ioff) for the same Si footprint. These results make the thermally stable gate-last FinFET flow a valuable candidate for sub-10 nm DRAM peripheral logic.

Thermally stable Nb-based metal contacts with low contact resistance

In earlier work on planar high-k/metal-gate based peripheral transistors, imec researchers lowered the source/drain contact resistance by improving the dopant profile and adding pre-amorphization implants. At IEDM in 2024, imec introduced a different approach: replacing the conventional Ti contact metal with Nb for pMOS devices.

The thermal stability of the Nb-based contact module was demonstrated for the first time. In addition, superior performance was observed when integrated into the gate-last FinFET platform: record low contact resistance, reduced overall parasitic resistance, and improved Ion.

Ahead of DRAM mass production

Imec pioneered peripheral transistor technology 10 years ahead of the industry’s mass production introduction. In its most recent R&D work, imec demonstrated an industry-relevant, thermally stable FinFET-based platform to meet the requirements for sub-10 nm DRAM. Multiple flavors have been developed as possible solutions for next-generation DRAM products, providing different levels of fabrication complexity and transistor performance.

More disruptive concepts are envisioned in the longer term to continue the DRAM scaling path. One of these is building the periphery on a separate wafer and integrating it with the memory array using advanced wafer bonding techniques. Although this approach comes with additional process steps, a true benefit is the relaxed requirement for thermal stability, as the periphery is now manufactured separately from the memory array.

Imec recently initiated R&D work on peripheral transistors for this new DRAM architecture, guided by insights obtained from planar and FinFET-based technology.

Alessio Spessot, technical account director, has been involved in developing advanced CMOS, DRAM, NAND, emerging memory array, and periphery during his stints at Micron, Numonyx, and STMicro.

Naoto Horiguchi, director of CMOS device technology at imec, has worked in Fujitsu and the University of California Santa Barbara while being involved in advanced CMOS device R&D.

Kyocera has developed an innovative mmWave phased array antenna module (PAAM) that simultaneously creates multiple beams in different directions at different frequencies. These PAAMs will be used in 5G FR2 infrastructure installations, enabling for example site co-location of different operators running networks on different frequency bands. To ensure optimal beam steering and beam directivity of their groundbreaking product, Kyocera relies on CATR-based multi-reflector OTA testing technology from Rohde & Schwarz.

Kyocera and Rohde & Schwarz will showcase at MWC 2025 in Barcelona the characterization of a novel mmWave PAAM design for FR2 applications. Crucial to the demonstration at the Kyocera booth (5E12) is the R&S ATS1800M 5G NR multi-directional mmWave test chamber from Rohde & Schwarz, designed for over-the-air (OTA) testing with an exceptionally small footprint.

Mobile communications that operate in the FR2 frequency range experience a high path loss, something that can be solved by using beamforming antenna arrays. In contrast to traditional antennas, FR2 antennas typically use phased arrays with a high number of individual antenna elements. Kyocera has developed a novel phased array antenna module (PAAM) featuring 384 dual polarization elements which is able to create up to 8 simultaneous beams in different directions at different frequencies. With this design, the PAAM can be used in site installations allowing multiple operators to run networks on different frequency bands.

However, all these antenna elements need to work perfectly together to form an RF beam with the desired characteristics. Rohde & Schwarz offers a patented approach for testing such a complex antenna array over- the-air (OTA) in a fully shielded environment, which helps engineers verify the correct beam pattern and supports the process of minimizing sidelobes.

The R&S ATS1800M is a unique solution that features four feed antennas and CATR reflectors, each with a 30 cm quiet zone (QZ). In the demonstration at MWC 2025, the Kyocera PAAM device under test (DUT) is placed on a rugged 3D positioner in the center, where all four QZs overlap, coming from multiple directions. This allows Kyocera’s engineers to address a variety of different tests, including the simultaneous reception of RF beams from four different directions, as will be shown at MWC 2025. Thanks to the vertical CATR design patented by Rohde & Schwarz, this setup takes up a fairly small footprint in the lab compared to other OTA-solutions.

The full test setup contains multiple test instruments from Rohde & Schwarz in addition to the mmWave test chamber, which work seamlessly together: four 5G NR-capable R&S SMW200A vector signal generators, a 5G NR-capable R&S FSW signal and spectrum analyzer, and an R&S NGP800 power supply. Each generator simulates a 5G NR FR2 signal which will be fed through one of the R&S ATS1800M feed antennas. The DUT receives the signal via one of the CATR reflectors. With the combination of all signal

sources, feed antennas and reflectors, Kyocera’s engineers can simulate complex reception scenarios of four frequency independent signals from four different locations. The received signal quality can be observed using the signal analyzer connected to the Kyocera PAAM.

Visitors to MWC 2025 can experience this milestone demonstration live at the Kyocera booth 5E12 in hall 5 of the Fira Gran Via in Barcelona from March 3 to 6, 2025.

Rheostats are simple and ubiquitous circuit elements, usually comprising a potentiometer connected as an adjustable two terminal resistor. The availability of manual pots with resistances spanning ohms to megohms makes the optimum choice of nominal resistance easy. But when an application calls for a digital potentiometer (Dpot), the problem can be challenging.

Wow the engineering world with your unique design: Design Ideas Submission Guide

Dpots are only available in a resistance range that’s narrow compared to manual pots. They also typically suffer from problematically high wiper resistance and resistance tolerance. These limitations conspire to make Dpots a difficult medium for implementing precision rheostats. Recent EDN design idea (DI) articles have addressed these issues with a variety of strategies and topologies:

• Op-amp wipes out DPOT wiper resistance
• Synthesize precision Dpot resistances that aren’t in the catalog
• Synthesize precision bipolar Dpot rheostats
• A class of programmable rheostats

While each of these designs corrects one or more complaints on the lengthy list of digital rheostat shortcomings, none fixes them all and some introduce complications of their own. Examples include crossover distortion, unreduced sensitivity to resistance tolerances, resolution-reducing nonlinearity of the programmed resistance, and just plain old complexity.

Figure 1’s circuit isn’t a perfect solution either. But it does synthesize an accurate programmed resistance equal to reference resistor R1 linearly multiplied by U1’s Rbw/Rab digital setting (the ratio between the terminal B to wiper resistance and total element resistance).

Figure 1 A precision digital rheostat that synthesizes an accurate programmed resistance equal to reference resistor R1 linearly multiplied by U1’s Rbw/Rab.

Here’s how it works.

 R = (Va – Vb)/Ia
R = R1/(Raw/Rbw + 1) = R1 Rbw/Rab
Rab = Raw + Rbw = typically 5k to 10k

Where R is the programmed synthetic resistance, R1 is the reference resistor, Raw is the resistance between terminal A and wiper terminal, Rbw is the resistance between B and wiper terminal, and Rab is the total element resistance.

U1 works in “voltage divider” (pot) mode to set the gain of inverting amplifier A2. Pot mode makes gain insensitive to both U1’s wiper resistance (Rw) and Rab. They really don’t matter much—see Figure 4-4 in the Microchip MCP41XXX/42XXX datasheet.

Turning the crank on Figure 1’s design equation math, we get:

Ga2 = Raw/Rbw

Where Ga2 is A2’s gain. Further,

Voltage across R1 = (Va – Vb) + Ga2(Va – Vb) = (Raw/Rbw + 1)(Va – Vb) =  Rab/Rbw(Va – Vb)
Current through R1 = Ia = Rab/Rbw(Va – Vb)/R1

Then, since R = (Va – Vb)/Ia:

R = R1*Rbw/Rab

Va is lightly loaded by A1’s ~10 picoamp (pA) input bias, so R1 can range from hundreds of ohms up to multiple megohms as the application may dictate. It should be precision, certainly 1% or better; then, programming and the math above takes over.

Figure 2 plots the linear relationship between R and Rbw.

Figure 2 Linear relationship between R and Rbw showing the circuit synthesizes an accurate programmed resistance equal to reference resistor R1 linearly multiplied by U1’s Rbw/Rab.

A compensation capacitor (C1) probably isn’t necessary for the parts selection shown in Figure 1 for A2 and U1. But if a faster amplifier or a higher resistance Dpot is chosen, then 10 pF to 20 pF would probably be prudent.

Meanwhile, I think it would be fair to say this design looks competitive with its peers. But earlier I described it as imperfect. Besides being a single-terminal topology (like two others on the list), where else does it fall short of being a complete solution to the ideal digital rheostat (Digistat) problem?

Here’s where: As Figure 3 shows, when the programmed value for R goes down, A2’s gain (Ga2) must go up. Reading the graph from right to left, we see gain rising moderately as R declines by 75% from R1 to R1/4 where, Rbw/Rab = 64/256 and gain = 3, but then it takes off. This tends to exaggerate errors like input offset, finite GBW and other op-amp nonidealities while creating the possibility of early A2 saturation at relatively low signal levels.

Figure 3 Graphs for Ga2 (red) and R/R1 (black) versus Rbw/Rab on the x-axis. When the programmed value for R goes down, Ga2 must go up.

The severity of the impact of these effects on utility of the design, whether mild, serious, or fatal, will depend on how low you need go in R/R1 and other specifics of the application. So, it’s certainly not perfect, but maybe it’s still useful somewhere.

And about that single terminal problem. If you have an application that absolutely requires a two-terminal programmable resistance, you might consider Figure 4. Depending on the external circuitry, it might not oscillate.

Figure 4 Duplicate and cross-connect Figure 1’s circuitry to get a two-terminal programmable resistance.

In closing…

Thanks to frequent contributor Christopher R. Paul for his clever innovations and stimulating discussions on this topic, I would likely never have come up with this design without his help. More thanks go to editor Aalyia Shaukat for her clever creation of this DI section that makes fun teamwork like this possible in the first place. This article would definitely never have happened without her help.

Stephen Woodward’s relationship with EDN’s DI column goes back quite a long way. Over 100 submissions have been accepted since his first contribution back in 1974.

A new network-on-chip (NoC) IP aims to dramatically accelerate chip development by introducing artificial intelligence (AI)-driven automation and reducing wire length to lower power use in system-on-chip (SoC) interconnect design. Arteris, which calls its newly introduced FlexGen interconnect IP a smart NoC, claims to deliver a 10x productivity boost, shortening design iterations from weeks to days.

Modern chips—connected by billions of wires—are ever-expanding with growing complexity. Modern SoCs have 5 to 20+ unique NoC instances, and each instance can require 5-10 iterations. As a result, SoC design complexity has surpassed manual human capabilities, which calls for smarter NoC automation.

“In SoC interconnect, while technology has advanced to new levels, a lot of work is still done in manual mode,” said Michal Siwinski, CMO of Arteris. FlexGen accelerates chip design by shortening and reducing iterations from weeks to days for greater efficiency.

“While FlexGen is still using the tried-and-tested NoC IP technology as basic building blocks, it automates the existing infrastructure by employing AI technology,” said Andy Nightingale, VP of product management and marketing at Arteris. “With FlexGen, we automate the NoC IP generation to reduce the manual work while opening high-quality configurations that rival or surpass the manual designs.”

Figure 1 A FlexNoC manual interconnect (above) is shown for an ADAS chip, while an automated FlexGen interconnect (blow) accelerates this chip design by up to 10x. Source: Arteris

According to Nightingale, it enhances engineering efficiency by 3x while delivering expert-quality results with optimized routing and reduced congestion. Dream Chip Technologies, a supplier of advanced driver assistance systems (ADAS) silicon solutions, acknowledges reducing design iterations from weeks to days while using FlexGen in its Zukimo 1.1 automotive ADAS chip design.

“FlexGen’s automated NoC IP generation allows us to create floorplan adaptive topologies with complex automotive traffic requirements within minutes,” said Jens Benndorf, GM at Dream Chip Technologies. “That enabled rapid experimentation to find design sweet spots and to respond quickly to floorplan changes with almost push-button timing closure.”

Shorter wire length

With AI comes a compute performance explosion, and as a result, the complexity of interconnects is going to exponential levels in SoC designs, leading to a huge explosion in the number of wires. FlexGen claims to reduce wire length by up to 30% to improve chip or chiplet power efficiency.

“We are also tackling the big problem of wire length in modern SoC designs,” said Nightingale. “As the gate count size reduces, it inevitably leads to dynamic power issues due to massive data traffic across wires.” By reducing wire length, FlexGen interconnect IP can reduce overall system power and thus help heating problems caused by the energy density of moving massive amounts of data across SoC interconnects.

Figure 2 FlexNoC manual interconnect (above) is shown with the best performance, while automated FlexGen (below) significantly reduces the interconnect wire length. Source: Arteris

Siwinski added that the number of gates doesn’t matter at smaller nodes. “Power from wire length kills you, so we reduce wire length to reduce overall power, performance, and area (PPA) in SoC designs.” That’s crucial as SoCs scale and become more powerful to meet the demands of applications like AI, autonomous driving, and cloud computing.

FlexGen is processor agnostic and supports Arm, RISC-V, and x86 processors. Moreover, its IP generation is highly repeatable to facilitate incremental design.

The latest radio resource management (RRM) conformance work item from the Global Certification Forum (GCF) has reached “Active” status following the approval of the Rohde & Schwarz R&S TS8980FTA-M1 5G conformance test system as the first to meet test platform approval criteria (TPAC). This includes the validation of RRM FR2 test cases in standalone mode (SA) for both one and two angles of arrival (1x AoA and 2xAoA) within 5G mmWave band combinations.

Rohde & Schwarz is the first company to obtain Global Certification Forum (GCF) test approval for validating the radio resource management (RRM) performance of advanced 5G New Radio (NR) devices. This approval specifically applies to devices operating in 5G NR standalone (SA) mode within FR2 and capable of managing multiple angles of arrival. It enables device manufacturers to certify their products for global compatibility with mobile networks that utilize mmWave frequencies and operate in 5G SA with a real 5G core network (5GC).

Verifying compliance with critical RRM test cases is increasingly important as wireless 5G routers and customer premises equipment (CPE) gain prominence for fixed wireless access (FWA) applications. These test cases are essential for ensuring a reliable end user experience, especially in challenging network conditions, such as blockages, or at the cell edge.

After the Conformance Agreement Group (CAG) #81 meeting held by GCF in Bangkok January 21 to 23, 2025, it was confirmed that Rohde & Schwarz is currently the only provider offering certification solutions that meet all mandatory test requirements for 5G FR2 RRM, while also supporting the largest number of validated test cases for both RF and RRM in this frequency range. The Rohde & Schwarz 5G mmWave test platform offers a wide range of advanced 5G FR2 non-standalone (NSA) and SA test cases. The platform is built on the CMX500 5G network emulator and includes the R&S ATS1800M anechoic chamber series as well as a powerful device under test (DUT) positioner.

Thomas Eyring, Senior Director of Device Certification at Rohde & Schwarz, commented on the milestone, saying: “We are proud to take a significant step toward enhanced conformance testing as a pioneer in mobile device testing. Our technology will help ensure the quality and reliability of 5G devices while addressing the

challenges in the FR2 frequency range. We are also working on test cases for the upcoming FR3 frequency range, which is expected to play a key role in 6G networks.”

The global semiconductor manufacturing industry closed 2024 with strong fourth quarter results and solid year-on-year (YoY) growth across most of the key industry segments, SEMI announced today in its Q4 2024 publication of the Semiconductor Manufacturing Monitor (SMM) Report, prepared in partnership with TechInsights. The industry outlook is cautiously optimistic at the start of 2025 as seasonality and macroeconomic uncertainty may impede near-term growth despite momentum from strong investments related to AI applications.

After declining in the first half of 2024, electronics sales bounced back later in the year resulting in a 2% annual increase. Electronics sales grew 4% YoY in Q4 2024 and are expected to see a 1% YoY increase in Q1 2025 impacted by seasonality. Integrated circuit (IC) sales rose by 29% YoY in Q4 2024 and continued growth is expected in Q1 2025 with a 23% increase YoY as AI-fueled demand continues boosting shipments of high-performance computing (HPC) and datacenter memory chips.

Similar to electronics sales, semiconductor capital expenditures (CapEx) decreased in the first half of 2024 but saw a strong rebound, particularly in the fourth quarter, resulting in 3% annual growth by the end of 2024. Memory-related CapEx continued to lead the growth surging 53% quarter-on-quarter (QoQ) and 56% YoY in Q4 2024. Non-memory CapEx also edged up in Q4 2024 showing 19% QoQ and 17% YoY improvement. Total CapEx is expected to remain strong in Q1 2025, growing 16% relative to the same period of the previous year on the strength of investments to support high bandwidth memory (HBM) capacity additions for AI deployment.

The semiconductor capital equipment segment remained resilient primarily due to increased investments into expanding leading-edge logic, advanced packaging and HBM capacity. Wafer fab equipment (WFE) spending increased 14% YoY and 8% QoQ in Q4 2024. Quarterly WFE billings are expected to be around $26 billion in Q1 2025. China’s investment continues to play a significant role in the WFE market but started to subside by end of the year. Additionally, back-end equipment showed strong increases in Q4 2024 with the Test segment logging 5% QoQ growth and an impressive 55% YoY increase for the quarter, while the Assembly and Packaging segment experienced a YoY increase of 15%. Both segments are expected to show similar QoQ growth between 6-8% in Q1 2025.

In Q4 2024, installed wafer fab capacity surpassed a record 42 million wafers per quarter worldwide (in 300mm wafer equivalent), and capacity is projected to reach nearly 42.7 million in Q1 2025. Foundry and Logic-related capacity continues to show stronger increases, growing 2.3% QoQ in Q4 2024, and the segment is projected to rise 2.1% in Q1 2025 driven by capacity expansion for advanced nodes. Memory capacity increased 1.1% in Q4 2024 and is forecasted to remain at the same level in Q1 2025 driven by strong demand for HBM.

“Despite seasonality and the challenges of macroeconomic uncertainty, momentum in AI-driven investments continues to fuel expansion across key segments, including memory, capital expenditures, and wafer fab equipment,” said Clark Tseng, Senior Director of Market Intelligence at SEMI. “Looking forward for 2025, the industry remains cautiously optimistic, with robust growth prospects driven by ongoing demand for high-performance computing and data center buildout.”

“As we begin the year, our expectation is for stronger performance in the second half, with semiconductor sales anticipated to remain flat sequentially in the first half, followed by a notable double-digit increase in the latter half,” said Boris Metodiev, Director of Market Analysis at TechInsights. “Inventory challenges persist for discrete, analog, and optoelectronic manufacturers, which will need to be addressed before we can expect widespread growth to resume.”
