Toshiba Completes New 300-Millimeter Wafer Fabrication Facility for Power Semiconductors

Toshiba Electronic Devices & Storage Corporation ("Toshiba") today held a ceremony to mark the completion of a new 300-millimeter wafer fabrication facility for power semiconductors and an office building at Kaga Toshiba Electronics Corporation in Ishikawa Prefecture, Japan, one of Toshiba's key group companies. The completion of construction is a major milestone for Phase 1 of Toshiba's multi-year investment program. Toshiba will now proceed with equipment installation, toward starting mass production in the second half of fiscal year 2024. Once Phase 1 reaches full-scale operation, Toshiba's production capacity for power semiconductors, mainly MOSFETs^[1] and IGBTs^[2], will be 2.5 times that of fiscal 2021, when the investment plan was made^[3]. Decisions on the construction and start of operation of Phase 2 will reflect market trends.

The new manufacturing building follows and will make a major contribution to Toshiba's Business Continuity Plan (BCP): it has a seismic isolation structure that absorbs earthquake shock and redundant power sources. Energy from renewable source and solar panels on the roof of the building (onsite PPA model) will allow the facility to meet 100% of its power requirement with renewable energy.

Product quality and production efficiency will be boosted by the use of artificial intelligence (AI). Toshiba expects to receive a grant from the Ministry of Economy, Trade and Industry of Japan to subsidize its investment in part of the manufacturing equipment.

Power semiconductors play a crucial role in electricity supply and control, and are essential devices for energy efficiency in all electrical equipment. With the continuing electrification of automobiles and the automation of industrial machinery, they are expected to see continued robust demand growth. Toshiba started power semiconductor production on a new 300-millimeter wafer line in the second half of fiscal 2022 at Kaga Toshiba Electronics' existing facility. Going forward, the company will expand production with the new fab and further contribute to carbon neutrality.
