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.

The CoolSiC MOSFETs 650 V showcase remarkable reliability even in harsh environments, making them an ideal choice for topologies with repetitive hard commutation. The inclusion of the innovative .XT interconnect technology further enhances the devices’ thermal performance by reducing the thermal resistance (R th) and thermal impedance (Z th). In addition, the new devices feature a gate threshold voltage (V GS(th)) greater than 4 V for robustness against parasitic turn-on, a robust body diode, and the strongest gate oxide (GOX) in the market resulting in extremely low FIT (failures in time) rates.
While a cut-off voltage (V GS(off)) of 0 V is generally recommended to simplify the driving circuit (unipolar driving), the new portfolio supports a wide driving interval of V GS voltage within the range of -5 V (turn-off) to 23 V (turn-on). This ensures ease-of-use and compatibility with other SiC MOSFETs and standard MOSFET gate-driver ICs. This is paired with higher reliability, reduced system complexity, and the enablement of automated assembly, reducing system and production costs and accelerating time-to-market.

NoMIS Power has achieved its latest major milestone with an award from the U.S. Air Force Research Laboratory (AFRL) to develop rugged Silicon Carbide (SiC) power devices to support the electrical power systems of aircraft.
NoMIS Power will develop 1200 V SiC power semiconductor devices (PSDs) through the award. The focus will be on metal-oxide-semiconductor field-effect transistors (MOSFETs) with enhanced operational lifetime as well as improved on-state and off-state efficiency at operating temperatures, resulting in lower losses for power electronics engineers to manage.
Solid-state power controllers within aircraft electrical power distribution systems require low on-state losses to enable passive cooling, as well as surge current and voltage overshoot protection during system start-up and fault interrupt. The proposed 1200 V SiC MOSFETs from NoMIS Power will provide airframers and system builders/integrators with the necessary PSD chips capable of high efficiency, long short-circuit withstand time (SCWT), and operational ruggedness for nominal and transient conditions. Moreover, the 1200 V rating will not only support current-generation aircraft utilizing 270 VDC architecture, but also aircraft operating with a +/- 270 VDC (i.e. 540 VDC rail-to-rail) architecture, as well.
NoMIS Power overcomes the limitations of commercial-off-the-shelf (COTS) Si and SiC-based PSDs via a novel SiC device design that is achievable using disruptive manufacturing techniques. As a result, NoMIS SiC devices can withstand higher voltage spikes and current surges during harsh operating conditions, enabling longer power management product lifetime through superior reliability and ruggedness.
Announcing the new award, NoMIS Power CEO Dr. Adam Morgan said, “Our team is very excited to get the opportunity to support strategic groups working to improve the capabilities of our armed forces. We are confident this novel SiC device technology will also have a significant impact on other critical technology markets, such as electric vehicles and grid infrastructure. These efforts will directly support our company’s near-term product launch of next-generation SiC devices.”
