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.
