The U.S. Department of Commerce’s Bureau of Industry and Security (BIS) announced a package of rules designed to further impair the People’s Republic of China’s (PRC) capability to produce advanced-node semiconductors that can be used in the next generation of advanced weapon systems and in artificial intelligence (AI) and advanced computing, which have significant military applications. This action is a proactive measure enhancing the Department of Commerce’s work to impede the PRC’s ability to procure and produce the technologies necessary for its military modernization.
The rules include new controls on 24 types of semiconductor manufacturing equipment and 3 types of software tools for developing or producing semiconductors; new controls on high-bandwidth memory (HBM); new red flag guidance to address compliance and diversion concerns; 140 Entity List additions and 14 modifications spanning PRC tool manufacturers, semiconductor fabs, and investment companies involved in advancing the PRC government’s military modernization; and several critical regulatory changes to enhance the effectiveness of our previous controls.
“This action is the culmination of the Biden-Harris Administration’s targeted approach, in concert with our allies and partners, to impair the PRC’s ability to indigenize the production of advanced technologies that pose a risk to our national security,” said U.S. Secretary of Commerce Gina Raimondo. “Further strengthening our export controls underscores the central role of the Department of Commerce in executing the United States’ broader national security strategy. No Administration has been tougher in strategically addressing China’s military modernization through export controls than the Biden-Harris Administration.”
“The United States has taken significant steps to protect our technology from being used by our adversaries in ways that threaten our national security. As technology evolves, and our adversaries seek new ways to evade restrictions, we will continue to work with our allies and partners to proactively and aggressively safeguard our world-leading technologies and know-how so they aren’t used to undermine our national security,” said National Security Advisor Jake Sullivan.
“This action builds on BIS’s laser-focused work, undertaken over the past few years, to impose strategic controls that have hindered the PRC’s ability to produce advanced semiconductors and AI capabilities directly impacting U.S. national security. We are constantly talking to our allies and partners as well as reassessing and updating our controls. Today’s announcement represents the next step in that ongoing work,” said Under Secretary of Commerce for Industry and Security Alan Estevez. “This package is proactive and innovative in how we are responding to increasingly sophisticated actors and complex supply chains. We must ensure that we stay ahead of the PRC by protecting our advanced technology.”
“The PRC’s Military-Civil Fusion strategy presents a significant risk that advanced node semiconductors will be used in military applications that threaten the security of the United States, as well as the security of our allies and partners,” said Assistant Secretary of Commerce for Export Administration Thea D. Rozman Kendler. “These rules build on previous actions taken in service of our longstanding goal: protecting our collective security by constraining the PRC’s ability to indigenize the most advanced technologies, without unduly interfering with the continuing trade of technology.”
“The purpose of these Entity List actions is to stop PRC companies from leveraging U.S. technology to indigenously produce advanced semiconductors,” said Matthew S. Axelrod, Assistant Secretary for Export Enforcement. “By adding key semiconductor fabrication facilities, equipment manufacturers, and investment companies to the Entity List, we are directly impeding the PRC’s military modernization, WMD programs, and ability to repress human rights.”
Taking Novel Approaches to Impair and Impede the PRC’s Military Modernization
Throughout the Biden-Harris Administration, in coordination with U.S. allies and partners, BIS has taken novel approaches to address an ever-changing geopolitical and technological landscape and respond to increasingly sophisticated threat actors.
All of the policy changes announced today are designed to limit the PRC’s ability to indigenize the production of advanced technologies – such as advanced-node integrated circuits and the equipment used to produce them – that pose a substantial risk to U.S. national security. The semiconductor manufacturing equipment controlled by today’s rules is needed to produce advanced-node integrated circuits, which are necessary for advanced weapon systems and advanced AI used in military applications.
Advancements in large-scale AI models have shown striking performance improvements across many human abilities and may be used in advanced military and intelligence applications. These models have the ability to rapidly review and synthesize large amounts of information into actionable points. Advanced AI models could be used for rapid response scenarios on the battlefield; lowering the barrier to develop cyberweapons or chemical, biological, radiological, or nuclear weapons; and utilizing facial and voice recognition to repress and surveil minorities and political dissidents.
This announcement underscores the United States’ “small yard, high fence” strategy and will restrict the PRC’s ability to produce technologies key to its military modernization or repression of human rights.
These actions serve two primary objectives:
- Slowing the PRC’s development of advanced AI that has the potential to change the future of warfare; and
- Impairing the PRC’s development of an indigenous semiconductor ecosystem – an ecosystem built at the expense of U.S. and allied national security.
In line with these objectives, BIS is implementing several regulatory measures, including but not limited to:
- New controls on semiconductor manufacturing equipment needed to produce advanced-node integrated circuits, including certain etch, deposition, lithography, ion implantation, annealing, metrology and inspection, and cleaning tools.
- New controls on software tools for developing or producing advanced-node integrated circuits, including certain software that increases the productivity of advanced machines or allows less-advanced machines to produce advanced chips.
- New controls on high-bandwidth memory (HBM). HBM is critical to both AI training and inference at scale and is a key component of advanced computing integrated circuits (ICs). The new controls apply to U.S.-origin HBM as well as foreign-produced HBM subject to the EAR under the advanced computing Foreign Direct Product (FDP) rule. Certain HBM will be eligible for authorization under new License Exception HBM.
- Addition of 140 entities to the Entity List, in addition to 14 modifications, including semiconductor fabs, tool companies, and investment companies that are acting at the behest of Beijing to further the PRC’s advanced chip goals which pose a risk to U.S. and allied national security.
- Establishment of two new Foreign Direct Product (FDP) rules and corresponding de minimis provisions:
- Semiconductor Manufacturing Equipment (SME) FDP: Extends jurisdiction over specified foreign-produced SME and related items if there is “knowledge” that the foreign-produced commodity is destined to Macau or a destination in Country Group D:5, including the PRC
- Footnote 5 (FN5) FDP: Extends jurisdiction over specified foreign-produced SME and related items if there is “knowledge” of certain involvement by an entity on or added to the Entity List with a FN5 designation. Such entities are being designated on the Entity List for specific national security or foreign policy concerns described in the Entity List companion rule, such as these entities’ involvement in supporting the PRC’s military modernization through the PRC’s attempts to produce advanced-node semiconductors, including for military end-uses.
- De minimis: Extends jurisdiction over specified foreign-produced SME and related items described in the above FDP rules that contain any amount of U.S.-origin integrated circuits.
- New software and technology controls, including restrictions on Electronic Computer Aided Design (ECAD) and Technology Computer Aided Design (TCAD) software and technology when there is “knowledge” that such items will be used for the design of advanced-node integrated circuits to be produced in Macau or a destination in Country Group D:5.
- Clarification to the EAR regarding existing controls on software keys. Export controls now apply to the export, reexport, or transfer (in-country) of software keys that allow access to the use of specific hardware or software or renewal of existing software and hardware use licenses.
In October 2022, BIS published an interim final rule (IFR) to restrict the PRC’s ability to both purchase and manufacture certain high-end semiconductors critical for military applications. As part of BIS’s commitment to continually evaluating the effectiveness of export controls, it released updated rules in October 2023 and April 2024. Today’s rules build on those efforts.

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.

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).

GaN / LATEST NEWS / TOP STORIES / WBG3 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.
