Not long ago, Toshiba Semiconductor announced the completion of the new 300-millimeter wafer manufacturing plant and office building for Kaga Toshiba Electronics Co., Ltd. (one of Toshiba's key group companies) located in Ishikawa Prefecture, Japan. Toshiba stated that the new factory aims to start mass production in the second half of the fiscal year 2024. Once the first phase of the project is fully operational, the production capacity of Toshiba's power semiconductors will be 2.5 times that of the investment plan established in the fiscal year 2021.

On December 20, 2023, Toshiba officially delisted, and those who have witnessed Toshiba's glory all feel that this may be the end of an era. However, the delisting is not an end for Toshiba. At that time, Toshiba's delisting was actually to get rid of the interference and control of external directors on the company's business decisions, and to completely reclaim the company's business decision-making power from foreign capital.

In 2015, Toshiba was exposed for long-term financial fraud, and its stock price plummeted, plunging the company into a severe financial crisis. In 2017, Toshiba spent a huge amount of money to acquire Westinghouse Electric Corporation in the United States, which was known as the "pioneer of nuclear power," but fell into huge losses as a result, and ultimately had to apply for bankruptcy protection, and the company's situation further deteriorated. By the end of the fiscal year 2016, Toshiba's financial situation had become so serious that its assets could not cover its liabilities, and its stock was downgraded from the main board to the small and medium board by the Tokyo Stock Exchange, with the risk of delisting looming.

In order to save this crisis, Toshiba had to take extreme measures at the end of 2017 and introduce external funds of up to 600 billion yen (about 30 billion yuan). Although this measure temporarily saved the company from delisting, the price was that 70% of Toshiba's shares were held by foreign capital. The strong entry of foreign capital had a profound impact on Toshiba's management structure and operational strategy.

The introduction of foreign capital led to a sharp increase in the number of external directors of Toshiba.

At the worst, there were as many as 10 out of 12 directors who had the right to make business decisions, accounting for more than 80%. These external directors have different opinions and it is difficult to form a unified strategic direction, which has caused confusion within the company about "whose company this is." What's more complicated is that these external directors, while nominating directors, can even decide their own compensation, which has sparked dissatisfaction and questioning within the company.

A bigger problem is that these foreign directors are not really concerned about Toshiba's reconstruction, they are more concerned about short-term investment returns and profit improvement. According to insiders, when overseas shareholders exercise their right to speak, it often leads to chaos in Toshiba's business strategy and management order, seriously hindering the company's normal development and operation.

After choosing to delist, Toshiba said that it will focus on developing power semiconductors in the future. The semiconductor new factory mentioned at the beginning is the power semiconductor expansion announced by Toshiba in conjunction with the investment before delisting. Toshiba and Rohm will invest 99.1 billion yen and 289.2 billion yen respectively to build new factories and production lines in Ishikawa Prefecture and Miyazaki Prefecture, Japan. Toshiba is mainly responsible for the production of silicon-based power semiconductors, while Rohm is mainly responsible for the production of silicon carbide power semiconductors; Rohm's products will also be sold under the Toshiba brand.

01Layoffs of 5,000 People, Betting on Power Semiconductors

On April 17, 2024, Toshiba Corporation announced a major layoff of 5,000 employees.

Toshiba plans to integrate four business subsidiaries, including energy businesses such as power generation and nuclear power plants, infrastructure businesses such as railways, mechanical hard disk drive (HDD) businesses, and power semiconductor device businesses, as well as information technology (IT), into the parent company. By unifying redundant departments such as general affairs and finance, reducing superfluous personnel, Toshiba will be able to achieve effective integration and sharing of resources, and further improve operational efficiency and management level.

In the mid-term management plan released in May, Toshiba stated that this move is aimed at paving the way for the company's future development, putting an end to the chaotic situation of the past, while adjusting the cost structure to ensure more rational allocation of resources. Toshiba has also clarified the direction of its business resource concentration - that is, the fields of electricity and power semiconductors.

Toshiba has a total of about 67,000 employees in Japan, and this layoff scale accounts for a considerable proportion. This is also the largest scale of layoffs that Toshiba has taken since the exposure of the financial fraud incident in 2015. Such a decisive move also shows Toshiba's confidence and determination in power semiconductors.

Power semiconductors play a crucial role in the supply and control of electricity and are key equipment for improving the energy efficiency of all electrical equipment. Japanese semiconductor companies have always been at the forefront of the power semiconductor market. According to the research report "Latest Trends and Technical Trends in Power Device Wafer Market" published by Fuji Keizai, a Japanese market research company, the power semiconductor market is expected to grow by 23.4% year-on-year in 2024, reaching 281.3 billion yen. The global market size of the new generation of semiconductors made from silicon carbide and other materials will reach 34.579 trillion yen by 2035, an increase of 8.8 times compared to 2023.

In the field of power semiconductors, Japanese manufacturers including Mitsubishi Electric, Fuji Electric, Toshiba, Renesas, and Rohm have strong competitiveness globally and have been competing for layout in the power semiconductor field in recent years.

In 2023, Mitsubishi Electric announced a new investment in SiC power semiconductors. The company's new high-efficiency SiC power semiconductor samples for electric vehicles will extend the driving range of electric vehicles by 5-10%. Since the mass production of electric vehicle power semiconductor modules by Mitsubishi Electric in 1997, up to the fiscal year 2022 (from April 2022 to March 2023), Mitsubishi Electric modules have been applied to 26 million vehicles.

Fuji Electric will invest 200 billion yen in the semiconductor field over the three years from 2024 to 2026. The focus will be on power semiconductors used for electric power control of pure electric vehicles (EVs), and plans to build a new production line for silicon carbide (SiC) power semiconductors in domestic factories to increase production capacity. The aim is to seize the continuously expanding demand and drive the next growth.

In April 2024, the 300mm power semiconductor production line of Renesas' Kofu factory was put into operation. Renesas Electronics invested 9 billion yen in equipment for the factory in mid-2022 and has now officially started operation. Renesas will start mass production of power semiconductors mainly based on IGBT in 2025, which will also double Renesas' current power semiconductor production capacity.It is not difficult to find that Japanese semiconductor manufacturers are accelerating the layout of power semiconductors, and behind this is their tension.

Who is rising in the power semiconductor market?

Part of the reason for the tension of Japanese semiconductor manufacturers comes from the rising power manufacturers in China.

According to the data from the China Business Industry Research Institute, the scale of China's power semiconductor market was about 1368.86 billion yuan in 2022, a year-on-year increase of 4.4%. It is predicted that the scale of China's power semiconductor market will grow to 1519.36 billion yuan in 2023, and will reach 1752.55 billion yuan in 2024. The rapid development of China's new energy automobile industry is the foundation of the development of China's power semiconductor market.

The automotive business of STMicroelectronics and NXP Semiconductors is an important source of the company's revenue. China is a must-compete place for automobile giants in both supply and demand, and such a soil naturally also breeds a considerable part of the local power semiconductor companies. Since 2024, China's power semiconductor companies have not stopped the pace of expansion, and there have been new developments in the power semiconductor industry chain manufacturers in May alone.
