  • Toshiba to Sample 1200V SiC MOSFETs in Bare Die Format

    Toshiba to Sample 1200V SiC MOSFETs in Bare Die Format

    3 Min Read

    Toshiba Electronics Europe GmbH has developed new 1200V silicon carbide (SiC) MOSFETs with low on-resistance (RDS(ON)) and high levels of reliability. The devices are particularly suited to applications within automotive traction inverters. They are now available and shipping as early test samples in bare die format – allowing customers to customise them to meet the needs of their applications.

    The new X5M007E120 uses a manufacturing process that reduces on-resistance per unit area by up to 30%. Unlike existing methods that utilise a striped-pattern construction, the new devices arrange the embedded Schottky barrier diodes (SBDs) in a check-pattern to achieve lower on-resistance.

    Many SiC MOSFETs increase on-resistance as body diodes are energised during reverse conduction, which can lead to reliability issues. Toshiba SiC MOSFETs alleviate this issue by preventing body diodes from operating as SBDs are embedded into the MOSFETs. This approach maintains the reduction in on-resistance while ensuring reliability during reverse conduction.

    With electric motors consuming over 40% of the world’s electrical energy, efficient operation is essential to sustainability. The re-arrangement of SBDs in this device has suppressed body diode energisation, and the upper limit of unipolar operation has increased to around double without increasing the SBD mounting area. Additionally, channel density is improved. These enhancements contribute to energy efficiency in applications, including motor control inverters.

    Reducing RDS(ON) within a SiC MOSFET can cause excess current flow during short-circuit operations. By adopting a deep barrier structure, the X5M007E120 reduces excessive current within the MOSFET section and leakage current in the SBDs section during short-circuit operation. This enables durability during short-circuit conditions while maintaining high levels of reliability against reverse conduction operation.

    The new X5M007E120 has a VDSS of 1200V and is rated for a drain current (ID) of 229A continuously, with 458A for pulsed operation (ID Pulse). RDS(ON) is as low as 7.2mΩ, and the device can operate with channel temperatures (Tch) as high as 175°C. The devices are AEC-Q100 qualified for automotive applications.

    Engineering samples of the new X5M007E120 are expected to ship during 2025, with mass production samples scheduled to start in 2026.

    Toshiba will continue to seek ways to further improve the characteristics of its products. The company will contribute to realising a decarbonised society by providing customers with power semiconductors for applications where energy efficiency is essential, such as inverters for motor control and power control systems for electrical vehicles.

  • Infineon Technologies Delivers Thinnest Si Power Wafer ever Made

    Infineon Technologies Presented Thinnest Si Power Wafer ever Made

    4 Min Read

    After announcing the world’s first 300-millimeter gallium nitride (GaN) power wafer and opening the world’s largest 200-millimeter silicon carbide (SiC) power fab in Kulim, Malaysia, Infineon Technologies AG has unveiled the next milestone in semiconductor manufacturing technology.

    Infineon has reached a breakthrough in handling and processing the thinnest silicon power wafers ever manufactured, with a thickness of only 20 micrometers and a diameter of 300 millimeters, in a high-scale semiconductor fab. The ultra-thin silicon wafers are only a quarter as thick as a human hair and half as thick as current state-of-the-art wafers of 40-60 micrometers.

    “The world’s thinnest silicon wafer is proof of our dedication to deliver outstanding customer value by pushing the technical boundaries of power semiconductor technology,” said Jochen Hanebeck, CEO at Infineon Technologies. “Infineon’s breakthrough in ultra-thin wafer technology marks a significant step forward in energy-efficient power solutions and helps us leverage the full potential of the global trends decarbonization and digitalization. With this technological masterpiece, we are solidifying our position as the industry’s innovation leader by mastering all three relevant semiconductor materials: Si, SiC and GaN.”

    This innovation will significantly help increase energy efficiency, power density and reliability in power conversion solutions for applications in AI data centers as well as consumer, motor control and computing applications. Halving the thickness of a wafer reduces the wafer’s substrate resistance by 50 percent, reducing power loss by more than 15 percent in power systems, compared to solutions based on conventional silicon wafers.

    For high-end AI server applications, where growing energy demand is driven by higher current levels, this is particularly important in power conversion: Here voltages have to be reduced from 230 V to a processor voltage below 1.8 V. The ultra-thin wafer technology boosts the vertical power delivery design, which is based on vertical Trench MOSFET technology and allows a very close connection to the AI chip processor, thus reducing power loss and enhancing overall efficiency.

    “The new ultra-thin wafer technology drives our ambition to power different AI server configurations from grid to core in the most energy efficient way,” said Adam White, Division President Power & Sensor Systems at Infineon. “As energy demand for AI data centers is rising significantly, energy efficiency gains more and more importance. For Infineon, this is a fast-growing business opportunity. With mid-double-digit growth rates, we expect our AI business to reach one billion euros within the next two years.”

    To overcome the technical hurdles in reducing wafer thickness to the order of 20 micrometers, Infineon engineers had to establish an innovative and unique wafer grinding approach, since the metal stack that holds the chip on the wafer is thicker than 20 micrometers. This significantly influences handling and processing the backside of the thin wafer.

    Additionally, technical and production-related challenges like wafer bow and wafer separation have a major impact on the backend assembly processes ensuring the stability and first-class robustness of the wafers. The 20-micrometer thin wafer process builds on Infineon’s existing manufacturing expertise and ensures that the new technology can be seamlessly integrated into existing high-volume Si production lines without incurring additional manufacturing complexity, thus guaranteeing the highest possible yield and supply security.

    The technology has been qualified and applied in Infineon’s Integrated Smart Power Stages (DC-DC converter) which have already been delivered to first customers. It underlines the company’s innovation leadership in semiconductor manufacturing as the holder of a strong patent portfolio related to the 20-micrometer wafer technology.

    With the current ramp up of the ultra-thin wafer technology Infineon expects a replacement of the existing conventional wafer technology for low voltage power converters within the next three to four years. This breakthrough is bolstering Infineon’s unique position in the market with the broadest product and technology portfolio including silicon, silicon carbide and gallium nitride-based devices which are key enablers of decarbonization and digitalization.

    Infineon will present the first ultra-thin silicon wafer publicly at electronica 2024 from 12 to 15 November in Munich (Hall C3, Stand 502).

    Texas Instruments Began Production of GaN Power Semiconductors in Japan

    3 Min Read

    Texas Instruments (TI) announced it has begun production of gallium nitride (GaN)-based power semiconductors at its factory in Aizu, Japan. Coupled with its existing GaN manufacturing in Dallas, Texas, TI will now internally manufacture four times more GaN-based power semiconductors, as Aizu ramps to production.

    “Building on more than a decade of expertise in GaN chip design and manufacturing, we have successfully qualified our 200mm GaN technology – the most scalable and cost-competitive way to manufacture GaN today – to start mass production in Aizu,” said Mohammad Yunus, TI’s senior vice president of Technology and Manufacturing. “This milestone enables us to manufacture more of our GaN chips internally as we grow our internal manufacturing to more than 95% by 2030, while also sourcing from multiple TI locations, ensuring a reliable supply of our entire GaN portfolio of high-power, energy-efficient semiconductors.”

    An alternative to silicon, GaN is a semiconductor material that offers benefits in energy-efficiency, switching speed, power solution size and weight, overall system cost, and performance under high temperatures and high-voltage conditions. GaN chips provide more power density, or power in smaller spaces, enabling applications such as power adapters for laptops and mobile phones, or smaller, more energy-efficient motors for heating and air conditioning systems and home appliances.

    Today, TI offers the widest portfolio of integrated GaN-based power semiconductors, ranging from low- to high-voltage, to enable the most energy-efficient, reliable and power-dense electronics.

    “With GaN, TI can deliver more power, more efficiently in a compact space, which is the primary market need driving innovation for many of our customers,” said Kannan Soundarapandian, vice president of High-Voltage Power at TI. “As designers of systems such as server power, solar energy generation and AC/DC adapters face challenges to reduce power consumption and enhance energy efficiency, they are increasingly demanding a reliable supply of TI’s high-performance GaN-based chips. TI’s product portfolio of integrated GaN power stages enables customers to achieve higher power density, improved ease of use and lower system cost.”

    Further, with the company’s proprietary GaN-on-silicon process, more than 80 million hours of reliability testing, and integrated protection features, TI GaN chips are designed to keep high-voltage systems safe.

    Using the most advanced equipment available for GaN chip manufacturing today, TI’s new capacity enables increased product performance and manufacturing process efficiency, as well as a cost advantage. Also, the more advanced, efficient tools used in TI’s expanded GaN manufacturing can produce smaller chips, packing even more power. This design innovation can be manufactured using less water, energy and raw materials, and end products that use GaN chips enjoy these same environmental benefits.

    The performance benefits of TI’s added GaN manufacturing also enable the company to scale its GaN chips to higher voltages, starting with 900V and increasing to higher voltages over time, furthering power-efficiency and size innovations for applications like robotics, renewable energy and server power supplies.

    In addition, TI’s expanded investment includes a successful pilot earlier this year for development of GaN manufacturing processes on 300mm wafers. Further, TI’s expanded GaN manufacturing processes are fully transferable to 300mm technology, positioning the company to readily scale to customer needs and move to 300mm in the future.

    Expanding supply and innovation in GaN technology is the latest example of TI’s commitment to responsible, sustainable manufacturing. TI has committed to use 100% renewable electricity in its U.S. operations by 2027, and worldwide by 2030.

    3 Min Read

    Affordability combined with high performance and efficiency is the key to making electric mobility accessible to a broader market. That’s why Infineon Technologies AG is introducing the HybridPACK™ Drive G2 Fusion, establishing a new power module standard for traction inverters in the e-mobility sector.

    The HybridPACK Drive G2 Fusion is the first plug’n’play power module that implements a combination of Infineon’s silicon and silicon carbide (SiC) technologies. This cutting-edge solution provides an ideal balance between performance and cost efficiency, giving more choice in the optimization of inverters.

    One of the main differences between silicon and SiC in power modules is that SiC has a higher thermal conductivity, breakdown voltage and switching speed, making it more efficient, but also more expensive than silicon-based power modules. With the new module, the SiC content per vehicle can be reduced, while maintaining vehicle performance and efficiency at a lower system cost. For example, system suppliers can realize nearly the system efficiency of a full SiC solution with only 30 percent SiC and 70 percent silicon area.

    “Our new HybridPACK Drive G2 Fusion module underlines Infineon’s innovation leadership in the automotive semiconductor industry,” said Negar Soufi-Amlashi, Senior Vice President & General Manager High Voltage at Infineon’s Automotive division. “Addressing the demand for greater e-mobility range, this technological breakthrough smartly combines silicon carbide and silicon. Integrated in a well-introduced module package footprint it offers compelling cost-performance ratio over pure silicon carbide modules without adding system complexity for automotive system suppliers and vehicle manufacturers.” 

    HybridPACK Drive G2 Fusion expands Infineon’s HybridPACK Drive power module portfolio and can be quickly and easily integrated in vehicle components or modules without requiring complex adjustments or configurations. The HybridPACK Drive G2 Fusion module features up to 220 kW in the 750 V class. It ensures high reliability over the entire temperature range from -40 °C to +175 °C and improved thermal conductivity.

    The unique properties of Infineon’s CoolSiC™ technology and its silicon IGBT EDT3 technology with very fast turn-on enable the use of a single gate driver or dual gate drivers. This allows easy re-design from full silicon or full SiC based inverters to a fusion inverter. Generally, Infineon’s holistic expertise in SiC MOSFET and silicon IGBT technology, power module packaging, gate drivers as well as sensors enables premium products with cost savings at system level. One example is the integration of Swoboda or XENSIV™ Hall sensors in the HybridPACK Drive package for more precise and efficient motor control.

    Infineon will showcase the new HybridPACK Drive G2 Fusion at electronica 2024 in Munich from November 12 to 15 (hall C3, booth 502).

    The U.S. Department of Commerce and Wolfspeed announced they have signed a non-binding preliminary memorandum of terms (PMT) for up to $750 million in proposed direct funding under the CHIPS and Science Act. In addition, a consortium of investment funds led by Apollo, The Baupost Group, Fidelity Management & Research Company and Capital Group have agreed to provide Wolfspeed an additional $750 million of new financing.

    Together these investments support Wolfspeed’s long-term growth plans and bolster domestic production of silicon carbide to power clean energy systems underpinning electric vehicles (EVs), artificial intelligence (AI) data centers, battery storage and more. In addition, Wolfspeed expects to receive $1 billion of cash tax refunds from the advanced manufacturing tax credit under the CHIPS and Science Act (section 48D), giving the company, in total, access to up to $2.5 billion of expected capital to support the expansion of silicon carbide manufacturing in the United States.

    Wolfspeed is the world’s largest producer of silicon carbide technology, pioneering the technology more than 35 years ago on the campus of North Carolina State University. Since that time, Wolfspeed has become the global leader in silicon carbide technology, one of the fastest growing components of the broader semiconductor industry.

    • Silicon carbide is a superior alternative to silicon for high power applications – such as EV powertrains, e-mobility, renewable energy systems, battery energy storage systems, and AI and cryptocurrency data centers – that unlocks improved performance and lower system costs.
    • Notably, the importance of bolstering the domestic production of silicon carbide has been recognized across multiple federal agencies; the Department of Energy denoted it as one of 17 “critical materials” with a high risk of supply disruption that are integral to clean energy technologies, while the Department of Commerce recognizes silicon carbide semiconductors as important to national security.
    • As the U.S. and the world pursue more efficient and environmentally friendly solutions to meet the world’s ever-increasing need for high-voltage energy products, it is crucial that the U.S. continue to make strategic investments to cement its technological leadership position, while continuing to spur American innovation in critical technologies.

    Wolfspeed CEO, Gregg Lowe, said, “To reach this milestone under the U.S. CHIPS and Science Act is an incredible achievement in Wolfspeed’s long-term growth strategy, and we believe today’s announcement is a testament to the market-leading quality of Wolfspeed products and significance of Wolfspeed to broader U.S. economic and national security interests. This support galvanizes our ability to expand domestic manufacturing, accelerate innovation in next-generation semiconductor technology, and meet the increasing global demand for silicon carbide.

Today’s massive investment will make America’s economy and our national security stronger as Wolfspeed helps us write the next chapter of America’s resurgence as the leader in the semiconductor industry, with the Mohawk Valley as the beating heart.”

    “Wolfspeed is a homegrown semiconductor innovator and manufacturer creating great jobs in North Carolina, and it’s important they received this major grant under the CHIPS and Science Act,” said North Carolina Governor Roy Cooper. “Thanks to this landmark legislation from the Biden-Harris Administration and our great workforce, we will continue to see good paying jobs coming to North Carolina.”

    “This $750 million federal investment is a testament to Wolfspeed’s unique leadership in silicon carbide semiconductor manufacturing, and I applaud Wolfspeed’s continued commitment to North Carolina,” said Senator Thom Tillis. “I was proud to vote for the CHIPS and Science Act to provide the funding for this investment in North Carolina and to support our economic and national security.”

    “North Carolina continues to be a leader in cutting-edge manufacturing that is vital to our country’s national and economic security,” said Senator Ted Budd. “This new Wolfspeed site in Siler City will bring good-paying jobs to the area and is an important first step in making sure America has secure supply chains for critical semi-conductors.”

    “We are pleased to expand our investment in Wolfspeed by providing additional capital in support of the company’s build out of its leading silicon carbide capabilities,” said Apollo Partner Joseph Jackson. “We believe Wolfspeed is at the forefront of a critical transformation in sustainable transportation and ensuring that the company has durable capital access to complete its expansion plans will help solidify its leadership in this space. Along with our lending consortium, which includes multiple funds that also own substantial equity stakes in the company, we believe this strategic investment will drive significant long-term value while advancing key tenets of the CHIPS and Science Act.”

    These proposed funds, which are expected to be received upon milestone achievements in the coming years, would enable Wolfspeed to complete its multi-billion-dollar greenfield U.S. capacity expansion plan, which consists of the largest and most advanced 200mm silicon carbide footprint in the world. In addition to the proposed direct funding, Wolfspeed intends to benefit from the U.S. Treasury Department Investment Tax Credit of up to 25% of the qualified capital expenditures primarily related to its construction and installation of equipment at The John Palmour Manufacturing Center for Silicon Carbide in Siler City, NC and completion of the Mohawk Valley Fab M-Line West Expansion in Utica, NY.

    Infineon Technologies Released Dual-Phase Power Modules for High-Performance AI Data Centers

    2 Min Read

    Data centers are currently responsible for more than two percent of global energy consumption. Fueled by AI, this number is expected to grow to up to around seven percent in 2030, matching the current energy consumption of India. Enabling efficient power conversion from grid-to-core is vital to enable superior power densities and thereby advance compute performance while reducing total cost of ownership (TCO).

    Infineon Technologies AG is therefore launching the TDM2354xD and TDM2354xT dual-phase power modules with best-in-class power density for high-performance AI data centers. These modules enable true vertical power delivery (VPD) and offer industry’s best current density of 1.6 A/mm2. They follow the TDM2254xD dual-phase power modules introduced by Infineon earlier this year.

    “We are proud to enable high-performance AI data centers with our TDM2354xT and TDM2354xD VPD modules. These devices will maximize system performance with Infineon’s trademark quality and robustness, thereby enabling best TCO for data centers,” said Rakesh Renganathan, Vice President Power ICs at Infineon Technologies. “Our industry-leading power devices and packaging technologies, combined with our extensive systems expertise, will further advance high-performance and green computing as part of our mission to drive digitalization and decarbonization.”

    The TDM2354xD and TDM2354xT modules combine Infineon’s robust OptiMOS™ 6 trench technology, a chip-embedded package that enables superior power density through enhanced electrical and thermal efficiencies, and a new inductor technology to enable lower profile and therefore, true vertical power delivery.

    As a result, the modules set new standards in power density and quality to maximize the compute performance and efficiency of AI data centers. The TDM2354xT modules support up to 160 A and are the industry’s first Trans-Inductor Voltage Regulator (TLVR) modules in a small 8 x 8 mm² form factor. Combined with Infineon’s XDP™ controllers, they offer extremely fast transient response and minimize on-board output capacitance by up to 50 percent, further increasing system power density.

    The new modules will be showcased at Infineon’s global technology forum OktoberTech™ 2024 in Silicon Valley on 17 October and at electronica 2024 in Munich from November 12 to 14 (hall C3, booth 502).
