Power semiconductors companies continue to invest heavily in new factories, production capacity expansions, and R&D centers. Thus, recently the total value of the active investment projects launched since 2021 has surpassed 70 billion USD.
Driven by the pandemic and geopolitics, major power semiconductors companies started to invest more in new factories and joint ventures to have more confidence in their own supply chain in the future.
As of today, it is obvious to see the major split of power semiconductors into three geographical regions – the USA, Europe, and Asia. Asia may as well be divided into several regions with China being the leading investor of all.
Despite the ongoing tensions and export restrictions between the US, Europe, and China related to advanced semiconductors, when it comes to power semiconductors European companies continue to invest in the Chinese market expanding their product capacity or establishing new joint ventures like STMicroelectronics and Sanan Optoelectronics did recently.
Even with some delay, Japanese companies like ROHM, Mitsubishi Electric, Fuji Electric, Renesas Electronics, Toshiba, and others, pushed by their US and European competitors, announced their own projects aimed to secure the capacity on the wafer and device level to correspond to the growing demand for Si and SiC based power semiconductors coming from the electric vehicle and charging, photovoltaics, battery energy storage systems, and the other emerging applications.
If we take a closer look at all projects announced, SiC is the leading technology with over 60% of total investment. Over 25 market leaders announced their plans to invest in silicon carbide.
Thus, ROHM is investing in new production to multiply its SiC capacity in the coming years. Mitsubishi Electric teams up with Coherent to scale manufacturing of SiC power devices on a 200 mm SiC technology platform as one of the steps of their 260 billion yen investment project planned till March 2026.
Infineon Technologies continues to bet on both local European and Asian markets investing in their new fab in Dresden and expanding backend operations in Indonesia. STMicroelectronics continues to invest in WBG semiconductors with the ongoing construction of a new wafer fab in Sicily announced in 2022.
With a global total number of new investment projects of over 80, the US companies Wolfspeed, onsemi, and Microchip Technology, similar to their European counterparts, invest locally, in Europe and Asian markets. Totally the US semiconductor companies announced new projects valued at almost 9 billion USD.
With the US and EU Chips Acts, and similar initiatives in China, Japan, South Korea, and some other countries, it is clear that the investment into power semiconductors industry will continue to reach 100 billion USD soon.

STMicroelectronics has begun volume production of e-mode PowerGaN HEMT (high-electron-mobility transistor) devices that simplify the design of high-efficiency power-conversion systems. The STPOWER™ GaN transistors raise performance in applications such as wall adapters, chargers, lighting systems, industrial power supplies, renewable energy applications, and in automotive electrification.
The first two products in the family, the SGT120R65AL and SGT65R65AL, are industrial-qualified 650V normally-off G-HEMT™ in a PowerFLAT 5×6 HV surface-mount package. They have current ratings of 15A and 25A, respectively, with typical on-resistance (RDS(on)) of 75mΩ and 49mΩ at 25°C.
Also, 3nC and 5.4nC total gate charge and low parasitic capacitances ensure minimal turn-on/turn-off energy losses. A Kelvin source connection allows optimized gate driving. In addition to the reduced size and weight of the power supplies and adapters, the two new GaN transistors provide higher efficiency, lower operating temperature, and extended life time.
In the coming months, ST will introduce new PowerGaN variants, i.e. automotive-qualified devices, as well as additional power-package options including PowerFLAT 8×8 DSC and LFPAK 12×12 for high power applications.
ST’s G-HEMT devices facilitate the transition to GaN wide-bandgap technology in power conversion. GaN transistors with the same breakdown voltage and RDS(on) as silicon alternatives can achieve lower total gate charge and parasitic capacitances, with zero reverse-recovery charge.
These properties raise efficiency and enhance switching performance, allowing higher switching frequency that permits smaller passive components thereby increasing power density. Applications can therefore become smaller with higher performance. In the future, GaN is also expected to enable new power-conversion topologies that will further improve efficiency and decrease power losses.

Transphorm, Inc. responded to the recent news regarding China export restrictions. Late Monday, July 3, 2023, China’s Ministry of Commerce stated that it will restrict the exports of materials related to two metals used in semiconductor manufacturing: gallium and germanium. Gallium nitride (GaN) wafer materials are listed as being affected by these regulations.
Transphorm manufactures high voltage GaN power semiconductors. Trimethylgallium (TMGa) is used to produce the GaN. The company confirmed that its primary TMGa suppliers are not based in China and that suppliers have confirmed to be well-positioned to meet forecasted demand. Transphorm is therefore securely positioned to continue manufacturing and supplying its GaN devices without interruption.
Transphorm also explained gallium is generally a byproduct resulting from refinement processes used to produce popular metals such as aluminum from bauxite ore. Aluminum is produced in numerous countries such as Australia, Brazil, India, Jamaica, and the United States among others.
Transphorm will continue to the monitor the situation as necessary but sees no direct impact on its current operations. Nor does the company see long-term sourcing issues.

STMicroelectronics’ first galvanically isolated gate driver for gallium-nitride (GaN) transistors, the STGAP2GS, trims dimensions and bill-of-materials costs in applications that demand superior wide-bandgap efficiency with robust safety and electrical protection.
The single-channel driver can be connected to a high-voltage rail up to 1200V, or 1700V with the STGAP2GSN narrow-body version, and provides gate-driving voltage up to 15V. Capable of sinking and sourcing up to 3A gate current to the connected GaN transistor, the driver ensures tightly controlled switching transitions up to high operating frequencies.
With minimal propagation delay across the isolation barrier, at just 45ns, the STGAP2GS ensures fast dynamic response. In addition, dV/dt transient immunity of ±100V/ns over the full temperature range guards against unwanted transistor gate change. The STGAP2GS is available with separate sink and source pins for easy tuning of the gate-driving operation and performance.
Saving the need for discrete components to provide optical isolation, the STGAP2GS driver eases the adoption of efficient and robust GaN technology in various consumer and industrial applications. These include power supplies in computer servers, factory-automation equipment, motor drivers, solar and wind power systems, home appliances, domestic fans, and wireless chargers.
In addition to integrating galvanic isolation, the driver also features built-in system protection including thermal shutdown and under-voltage lockout (UVLO) optimized for GaN technology, to ensure reliability and ruggedness.
Two demonstration boards, the EVSTGAP2GS and EVSTGAP2GSN, combine the standard STGAP2GS and narrow STGAP2GSN with ST’s SGT120R65AL 75mΩ, 650V enhancement-Mode GaN transistors to help users evaluate the drivers’ capabilities.
The STGAP2GS in SO-8 widebody package, and the STGAP2GSN SO-8 narrow version, are available now, priced from $1.42 for orders of 1000 pieces.

Navitas Semiconductor has confirmed continued supply of leading-edge gallium nitride (GaN) power ICs. On July 3rd, 2023, China’s Ministry of Commerce announced it would put in place certain restrictions on the exporting of gallium and germanium, among other materials, starting in August. Navitas’ wafer technology is ‘GaN-on-Si’. The wafer subcontract manufacturer has verified that their production remains unaffected by the export restrictions, given multiple sources of gallium world-wide.
As a result, Navitas does not expect customer deliveries to be impacted or its business to be adversely affected by the export restrictions.
Significant sources of gallium are available worldwide, as it is a natural by-product in the production of other metals such as aluminum. Navitas does not use germanium in any product.

Nidec Corporation and Renesas Electronics Corporation have agreed to join forces on the development of semiconductor solutions for a next-generation E-Axle (X-in-1 system) that integrates an EV drive motor and power electronics for electric vehicles (EVs).
Today’s EVs are increasingly adopting the 3-in-1 unit called E-Axle, which integrates a motor, inverter, and gearbox (reduction gear). To realize high-performance and efficiency as well as smaller size, light weight and lower cost, and to accelerate vehicle development, EVs are also integrating power electronics controls such as DC-DC converters and on-board chargers (OBCs). EV manufacturers in advanced markets such as China have developed an X-in-1 platform that integrates multiple functions, accelerating the adoption in many vehicle models.
As X-in-1 integrates multiple functions and increases in complexity, maintaining a high-level of quality in vehicles becomes challenging. Thus, developing preventive safety technologies such as diagnostic functions and failure prediction is crucial for ensuring safety and security in vehicles. To address this challenge, the two companies agreed to combine Nidec’s motor technology and Renesas’ semiconductor technology to jointly develop a highly reliable and high-performance proof of concept (PoC) for the X-in-1 system. The PoC is designed to support the industry’s highest performance and efficiency as well as smaller size, light weight and lower cost for the X-in-1 system.
The companies plan to launch the first PoC by the end of 2023, which will feature a 6-in-1 system with a DC-DC converter, OBC, and power distribution unit (PDU) as well as a motor, inverter, and gearbox. As a second phase in 2024, Nidec and Renesas plan to develop a highly integrated X-in-1 PoC that incorporates a battery management system (BMS) along with other components. The first PoC will include power devices based on SiC (silicon carbide), and the second PoC will replace the DC-DC and OBC power devices with GaN (gallium nitride), offering excellent performance in high-frequency operation, to further reduce size and cost.
Building on the PoC developed through this collaboration, Nidec plans to rapidly productize E-Axle systems to add to its portfolio and ramp up to mass production to lead the E-Axle market. Renesas plans to develop and deliver turnkey solutions for increasingly complex X-in-1 systems by expanding the jointly developed PoC for E-Axle reference designs.
