Renesas to convert closed factory to 300mm wafer fab

Renesas plans to conduct a JPY 90 billion (EUR 664 million) investment in its Kofu factory, located in Kai City, Yamanashi Prefecture, Japan. The company closed the factory back in October 2014, but now intends to reopen the fab in 2024 as a 300mm wafer fab.

Demand for highly efficient power semiconductors keeps rising as the momentum for carbon neutrality grows. The Japanese company says it anticipates rapid growth in demand for EVs and therefore plans to enhance its production capacity for power semiconductors such as IGBTs. Once the Kofu Factory reaches its mass production, the total production capacity of Renesas’ power semiconductors will double, a press release reads.

At the Kofu factory, Renesas previously operated both 150mm and 200mm wafer fabrication lines. In order to boost its production capacity, the company has decided to utilise a remaining building of the factory and revive it as a 300mm wafer fab – dedicated to power semiconductors.

“This investment enables us to have our largest wafer fabrication line dedicated to power semiconductors, which are key to realizing decarbonization. We will continue to conduct necessary investments to enhance our in-house production capability while further strengthening ties with outsource partners. To address the mid to longer term demand growth, Renesas remains committed to ensuring security of supply in order to provide our customers with the best possible support,” says Hidetoshi Shibata, President and CEO of Renesas in the press release.

The Kofu fab will offer Renesas 18,000 square meters of clean room space. Once up and running the company will manufacture IGBT and Power MOSFET products.
