Gallium Nitride (GaN) technology plays a crucial role in enabling power electronics to reach the highest levels of performance. However, GaN suppliers have thus far taken different approaches to package types and sizes, leading to fragmentation and lack of multiple footprint-compatible sources for customers. Infineon Technologies AG addresses this challenge by announcing the high-performance gallium nitride CoolGaN G3 Transistor 100 V in RQFN 5×6 package (IGD015S10S1) and 80 V in RQFN 3.3×3.3 package (IGE033S08S1).

“The new devices are compatible with industry-standard silicon MOSFET packages, meeting customer demands for a standardized footprint, easier handling and faster-time-to- market,” said, Dr. Antoine Jalabert, Product Line Head for mid-voltage GaN at Infineon.

The CoolGaN G3 100 V Transistor devices will be available in a 5×6 RQFN package with a typical on-resistance of 1.1 mΩ. Additionally, the 80 V transistor in a 3.3×3.3 RQFN package has a typical resistance of 2.3 mΩ. These transistors offer a footprint that, for the first time, allows for easy multi-sourcing strategies and complementary layouts to Silicon-based designs. The new packages in combination with GaN offer a low-resistance connection and low parasitics, enabling high performance transistor output in a familiar footprint.

Moreover, this chip and package combination allows for high level of robustness in terms of thermal cycling, in addition to improved thermal conductivity, as heat is better distributed and dissipated due to the larger exposed surface area and higher copper density.

At NORD DRIVESYSTEMS, our sustainability strategy for 2025 focuses on acting in an environmentally conscious, responsible and integer manner. A cross-divisional team as well as the management and owners are part of the implementation. Besides NORD’s products, it includes four further fields of action.

 “Our sustainability strategy for 2025 is a promise to our customers, to the public and to ourselves to consequently act in an ecological, economic and socially responsible manner”, emphasizes Carolin von Rönne from the area of Process and Organisational Development & Corporate Sustainability Management at NORD DRIVESYSTEMS. The strategy comprises five key aspects:

When it comes to sustainability, our products at NORD are also our top priority. This is because the design, life cycle and application areas have an impact on the environment. The concept of sustainability is therefore already rooted in the product development process. “Drives can be found in many areas of industry, where they consume a large proportion of the energy used,” explains Carolin von Rönne. “With efficient drive solutions such as the IE5+ synchronous motor, we want to make a significant contribution to reducing CO₂ emissions.“ The NORD ECO service furthermore supports companies in finding the most efficient drive solutions for them.

The sustainability management was introduced at NORD in 2022. Since then, the company has achieved important milestones such as an annual sustainability report according to GRI, environmental certifications and the integration of international structures. The central objective in this field of action is the establishment of an international governance structure and CSRD-compliant reporting for the entire NORD DRIVESYSTEMS Group with 48 subsidiaries in 36 countries because the success of other factors – in

In order to coordinate structured measures and document them in a legally secure manner, international environmental management is essential for NORD. This is implemented in accordance with ISO14001 for the largest subsidiaries. In addition, the climate balance for Scope 1–3 is determined group-wide. NORD DRIVESYSTEMS Group further aims to reduce its energy consumption and amount of waste as well as increase the share of self-produced electric power and the use of renewable energies. Existing biodiversity areas are to be further expanded.

In times of skills shortage, NORD continues to increase its attractiveness as an employer. The company is currently rolling out a global digital learning management system to offer all employees the opportunity for further individual development. Further targeted campaigns and measures are intended to promote diversity among the workforce. “Inclusion, respect for human rights, strengthening our work culture, safety and continuous transfer of knowledge are only some of the topics we would like to promote”, says Carolin von Rönne.

NORD wants to reassure its customers and employees that sustainable production is given high priority both at manufacturing facilities and in the upstream supply chain. Risk analyses and other processes are carried out within the framework of the Germany Act on Corporate Due Diligence Obligations in Supply Chains (LKSG).

For decades, compute architectures have relied on dynamic random-access memory (DRAM) as their main memory, providing temporary storage from which processing units retrieve data and program code. The high-speed operation, large integration density, cost-effectiveness, and excellent reliability have contributed to the widespread adoption of DRAM technology in many electronic devices.

DRAM bit cell—the element that stores one bit of information—has a very basic structure. It consists of one capacitor (1C) and one transistor (1T) integrated close to the capacitor. While the capacitor’s role is to store a charge, the transistor is used to access the capacitor, either to read how much charge is stored or to store a new charge.

The 1T-1C bit cells are arranged in arrays containing word and bit lines, and the word line is connected to the transistors’ gate, which controls access to the capacitor. The memory state can be read by sensing the stored charge on the capacitor via the bit line.

Over the years, the memory community introduced subsequent generations of DRAM technology, enabled by continuous bit-cell density scaling. Current DRAM chips belong to the ’10-nm class’ (denoted as D1x, D1y, D1z, D1a…), where the half pitches of the active area in the memory cell array range from 19 nm down to 10 nm. However, the AI-driven demand for better performing and larger capacity DRAM is propelling R&D into beyond 10-nm generations.

This requires innovations in capacitors, access transistors, and bit cell architectures. Examples of such innovations are high-aspect ratio pillar capacitors, the move from saddle-shaped (FinFET-based) access transistors to vertical-gate architectures, and the transition from 6F2 to 4F2 cell designs—F being the minimum feature size for a given technology node.

A closer look inside a planar 1T-1C DRAM chip: The peripheral circuit

To enable full functionality of the DRAM chip, several other transistors are needed besides the access transistors. These additional transistors play a role in, for example, the address decoder, sense amplifier, or output buffer function. They are called DRAM peripheral transistors and are traditionally fabricated next to the DRAM memory array area.

Figure 1 The 1T-1C-based DRAM memory array and DRAM peripheral area are shown inside a DRAM chip. Source: imec

DRAM peripheral transistors can be grouped into three main categories. The first category is regular logic transistors: digital switches that are repeatedly turned on and off. The second category is sense amplifiers—analog types of transistors that sense the difference in charge between two-bit cells. A small positive change is amplified into a high voltage (representing a logic 1) and a small negative change into zero voltage (representing a logical 0).

These logical values are then stored in a structure of latches called the row buffer. The sense amplifiers typically reside close to the memory array, consuming a significant area of the DRAM chip. The third category is row decoders: transistors that pass a relatively high bias (typically around 3 V) to the memory element to support the write operation.

To keep pace with the node-to-node improvement of the memory array, the DRAM periphery evolves accordingly in terms of area reduction and performance enhancement. In the longer term, more disruptive solutions may be envisioned that break the traditional ‘2D’ DRAM chip architecture. One option is to fabricate the DRAM periphery on a separate wafer, and bond it to the wafer that contains the memory array, following an approach introduced in 3D NAND.

Toward a single and thermally stable platform optimized for peripheral transistors

The three groups of peripheral transistors come with their own requirements. The regular logic transistors must have good short channel control, high on current (Ion), and low off current (Ioff). With these characteristics, they closely resemble the logic transistors that are part of typical systems-on-chips (SoCs). They also need to enable multiple threshold voltages (Vth) to satisfy different design requirements.

The other two categories have more dissimilar characteristics and do not exist in typical logic SoCs. The analog sense amplifier requires good amplification, benefitting from a low threshold voltage (Vth). In addition, since signals are amplified, the mismatch between two neighboring sense amplifiers must be as low as possible. The ideal sense amplifier, therefore, is a very repeatable transistor with good analog functionality.

Finally, the row decoder is a digital transistor that needs an exceptionally thick gate oxide—compared to an advanced logic node—to sustain the higher bias. This makes the transistor inherently more reliable at the expense of being slower in operation.

Figure 2 Here are the main steps needed to fabricate a transistor for DRAM peripheral applications; the critical modules requiring specific developments are underlined. Source: PSS

In addition to these specific requirements, there are a number of constraints that apply to all peripheral transistors. One critical issue is the thermal stability. In current DRAM process flows with DRAM memory arrays sitting next to the periphery, peripheral transistors are fabricated before DRAM memory elements. The periphery is thus subjected to several thermal treatments imposed by the fabrication of the storage capacitor, access transistor, and memory back-end-of-line.

Peripheral transistors must, therefore, be able to withstand ‘DRAM memory anneal’ temperatures as high as 550-600°C for several hours. Next, the cost-effectiveness of DRAM chips must be preserved, driving the integration choices toward simpler process solutions than what logic flows are generally using.

To keep costs down, the memory industry also favors a single technology platform for various peripheral transistors—despite their individual needs. Additionally, there is a more aggressive requirement for low leakage and low power consumption, which benefits multiple DRAM use cases, especially mobile ones.

The combination of all these specifications makes a direct copy of the standard logic process flow impossible. It requires optimization of specific modules, including the transistors’ gate stack, source/drain junctions, and source/drain metal contacts.

Older folks may recall the famous Tektronix 576 and 577 curve tracers from half a century ago. A few of these have survived the decades and ended up in some lucky engineer’s home/work lab.

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

We were able to acquire a Tek 577 curve tracer with a Tek 177 standard test fixture from a local surplus house that had been used at Sandia Labs, but it was not functional. Even being non-functional, these old relics still command a high price, which set us back $500!! With the help of an on-line service manual and some detailed troubleshooting, the old 577 was revived by replacing all the power supply’s electrolytic capacitors and a few op-amps, plus removing the modifications Sandia had installed.

Once operational we went looking for the various Tek device under test (DUT) adapters for the Tek 177 standard test fixture, these adapters are indeed rare and likewise expensive which sent us on the DIY journey!

Observing a similar path to Jay_Diddy_B1 [1], we set out to develop a DIY adapter to replace the rare and expensive Tek versions. Like the popular T7 multi-function component tester, which employs a small ZIF socket for leaded-component attachment that works very well; we decided to do the same for the custom Tek adapter using the right and left sides of the ZIF socket to facilitate DUT comparisons with the Tek 177 standard test fixture. This can be seen in Figure 1.

Figure 1 Custom ZIF-based Tek 577 adapter where the right and left sides of the ZIF socket facilitate DUT comparisons with the Tek 177 standard test fixture.

As shown in Figure 2, a low-cost PCB was developed with SMD ferrites added to the nominal “Collector” and “Base” 577 terminals to help suppress any parasitic DUT oscillations. Connectors were also added to allow for external cables if desired (something we have never used). The general idea was to use the 6 banana jacks as support for holding the PCB in place with the ZIF on top of the PCB where one can directly attach various DUTs.

This approach has worked well and allows easy attachment of various leaded-components including the T0-126 and T0-220 power devices.

Figure 2 The custom adapter installed on the Tek 177 standard test fixture.

However, this still leaves the SMD types in need of a simple means to apply with the Tek 577 curve tracer with the 177 fixture; we set out to investigate this.

After studying the methods Tektronix utilized, we discovered some low-cost toggle clamps (found on AliExpress and elsewhere) which are used for clamping planar objects to a surface for machining. Figure 3 shows the custom toggle clamps used on a custom SMD DUT along with the custom adapter installed on the Tek 177 standard text fixture.

Figure 3 Custom toggle-type SMD adapter for the Tek 577 where using the pair of toggle arms allows both the right and left sides of the Tek 177 fixture to be utilized for direct SMD component comparisons.

These clamps could be repurposed to act as a clamp to hold a SMD DUT in place, which resulted in a custom PCB being developed to mount directly on top of the ZIF-based PCB previously discussed (Figure 4).

Figure 4 The custom SMD PCB that can be used with toggle clamps. This can be installed on the Tek 177 fixture for the Tek 577.

The toggle arms allow slight pressure to be applied to the SMD DUT where the leads make contact with the PCB’s exposed surfaces. Using a pair of toggle arms allows both the right and left sides of the Tek 177 fixture to be utilized for direct SMD component comparisons.

A connector on the rear of the PCB is mounted on the bottom side and mates with another connector on the ZIF type PCB, which allows connection to the 6 banana jacks that plug into the Tek 177 Fixture. Four nylon standoffs provide mechanical support and hold the two PCBs together. This setup allows easy SMD component installation and removal with little effort. Figure 5 shows both adapters for the Tek 577 with 177 standard test fixture.

Figure 5 Both adapters for the Tek 577 with 177 standard test fixture.

Both the ZIF and the SMD Adapters have served well and allow most components to be easily evaluated with the old Tektronix 576 and 577 curve tracers. Figure 6 shows the custom toggle-type SMD adapter in action with pair of DUTs.

Figure 6 Custom toggle-type SMD adapter in operation with pair of DUTs.

Just a word of caution when using these and any adapters, fixtures, or leads with the Tek 576 and 577 curve tracers: these instruments can produce lethal voltages across the exposed terminals. The Tek 177 standard test fixtures were originally supplied with plastic protective covers and sensor switches which removed the DUT stimulus when the plastic cover was open. In the old Tek service manuals, there was a modification method to defeat the Tek 177 sensor switch which many engineers employed, and many also removed the plastic protective covers.

Anyway, I hope some folks lucky enough to have an old Tek 576 or 577 curve tracer with Tek 177 standard test fixture find these custom DIY adapters useful if they don’t already have the old Tek OEM elusive adapters!
