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.

Mitsubishi Electric Corporation announced that it will begin shipping samples of its new NX-type full-SiC (silicon carbide) power semiconductor module for industrial equipment on June 14. The module, which reduces internal inductance and incorporates a second-generation SiC chip, is expected to contribute to the realization of more efficient, smaller and lighter-weight industrial equipment.
Power semiconductors are increasingly being utilized to convert electric power extra efficiently and thereby help to lower the carbon footprint of global society. Expectations are particularly high for SiC power semiconductors because of their capability to significantly reduce power loss. The demand is expanding for high-power, high-efficiency power semiconductors capable of improving the power-conversion efficiency of components such as inverters used in industrial equipment.
Mitsubishi Electric began releasing power semiconductor modules equipped with SiC chips in 2010. The new module, which features a low-loss SiC chip and optimized electrode structure, reduces internal inductance by 47% compared to its existing predecessor, enabling reduced power loss. Development of this SiC product have been partially supported by Japan’s New Energy and Industrial Technology Development Organization (NEDO).

Mitsubishi Electric Corporation announced that it has developed a new structure for a silicon carbide metal-oxide-semiconductor field-effect transistor (SiC-MOSFET) embedded with a Schottky barrier diode (SBD), which the company has applied in a 3.3 kV full SiC power module, the FMF 800 DC -66 BEW for large industrial equipment such as railways and DC power systems. Samples began shipping on May 31. The chip’s new structure is expected to help downsize railway traction systems, etc. as well as make them more energy efficient, and contribute to carbon neutrality through the increased adoption of DC power transmission.
SiC power semiconductors are attracting attention with their capacity to significantly reduce power loss. Mitsubishi Electric, which commercialized SiC power modules equipped with SiC-MOSFETs and SiC-SBDs in 2010, has adopted SiC power semiconductors for a variety of inverter systems, including air conditioners and railways.
The chip integrated with a SiC-MOSFET and a SiC-SBD can be mounted on a module more compactly compared to the conventional method of using separate chips, thus enabling smaller modules, larger capacity, and lower switching loss. It is expected to be widely used in large industrial equipment such as railways and electric power systems. Until now, the practical application of power modules with SBD-embedded SiC-MOSFETs has been difficult due to their relatively low surge-current capability, which results in the thermal destruction of the chips during surge-current events because surge currents in connected circuits concentrate only in specific chips.
Mitsubishi Electric has now developed the world’s first mechanism by which surge current concentrates on a specific chip in a parallel-connected chip structure inside a power module, and a new chip structure in which all chips start energizing simultaneously so that surge current is distributed throughout each chip. As a result, the power module’s surge-current capacity has been improved by a factor of five or more compared to the company’s existing technology, which is equal to or greater than that of conventional Si power modules, thus enabling the application of an SBD-embedded SiC-MOSFET in a power module.
