Renesas begins operations of Kofu Factory as dedicated 300-mm wafer fab for power semiconductors

Renesas Electronics Corporation, a premier supplier of advanced semiconductor solutions, has started operations at its Kofu Factory, located in Kai City, Yamanashi Prefecture, Japan. Renesas aims to boost its production capacity of power semiconductors in anticipation of the growing demand in electric vehicles (EVs).

The Kofu Factory previously operated both 150mm and 200mm wafer fabrication lines under Renesas Semiconductor Manufacturing a wholly owned subsidiary of Renesas, but ceased operations in October 2014. Renesas made the decision to re-open the factory in May 2022 as a 300-mm wafer fab to support the growing demand for power semiconductors, which is propelled by the industry-wide goal to realize a decarbonized society.

Renesas conducted a 90-billion-yen (US$588 million) worth investment in 2022 and has now started operations. The factory will start mass production of IGBTs and other products in 2025, doubling Renesas’ current production capacity for power semiconductors.
