Toshiba and Rohm to Jointly Produce Power Semiconductors

Update time : 2023-12-14 10:16:24

According to an application plan submitted to the Japanese Ministry of Economy, Trade and Industry (METI), Toshiba and Rohm will invest 380 billion yen (about 2.7 billion U.S. dollars) in the joint production of power chips, of which Japan's Ministry of Economy, Trade and Industry (METI) will provide up to one-third of the subsidies, that is, 120 billion yen (830 million U.S. dollars) of the funds.
At the same time, as part of the cooperative project, Toshiba will plan to invest in Rohm Semiconductor's new factory in Miyazaki Prefecture, Kyushu, Japan.
On November 7, Rohm completed the acquisition of assets of the company's former Kokufu plant. It is reported that the factory after renovation, will be the second factory in Miyazaki as a manufacturing subsidiary of Rohm's - Blue Boulder Semiconductor Corporation into operation. The plant is scheduled to begin production in 2024 as the main production base for Rohm's SiC power semiconductors.
In addition, Rohm invested in a new plant at its Malaysian manufacturing subsidiary, ROHM-Wako Electronics (Malaysia) Sdn. Bhd. (hereinafter referred to as "RWEM"), which was completed on October 17th, in order to strengthen its analog IC production capacity.
Isolated gate drivers are ICs used to appropriately drive power semiconductors such as IGBTs and SiCs, and play an important role in realizing energy saving and miniaturization of electric vehicles and industrial equipment. In order to increase the number of analog IC production bases, RWEM will start production of ICs for the first time and is scheduled to start production in October 2024. Upon commencement of production, RWEM's overall production capacity is expected to increase by approximately 1.5 times.
Toshiba Materials, a subsidiary of the Toshiba Group, is actively investing in increasing production of automotive-grade silicon nitride spheres as demand for automotive electrification continues to advance.
On July 25, Toshiba Materials announced a major investment in a new production facility to increase the capacity of silicon nitride spheres. The facility will be built at the company's Oita plant in northern Kyushu, Japan, and the 7 billion yen (approximately $50 million) project is expected to begin production in January 2026.
In July 2022, the company had also announced an expansion at its Yokohama headquarters, increasing production by 50 percent. And when the new Oita plant reaches full capacity, production capacity will be 2.5 times the 2022 level.
