TOKYO, August 29, 2023 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that the company has completed installation of its first 12-inch silicon wafer processing line at its Power Device Work's Fukuyama Factory, which manufactures power semiconductors. In addition, through sample production and testing, it has been verified that the power semiconductor chips processed on this production line achieve the required performance levels.

As previously announced, Mitsubishi Electric is planning to start mass production on the new 12-inch silicon wafer line in fiscal 2025. The company aims to approximately double its silicon power semiconductor wafer processing capacity by fiscal 2026 compared to fiscal 2021 levels.

In recent years, the demand for power semiconductors offering efficient control of electrical power is growing as countries look to achieve carbon-free status. Power semiconductors are utilized in wide range of relevant products, including electric vehicles, consumer devices (e.g. air-conditioning systems), industrial equipment, renewable energy and traction devices, and a stable supply is required in order to meet this growing demand.

Mitsubishi Electric will contribute to the realization of a carbon-free society through enhancement of its production capacity and by ensuring a stable supply of power semiconductors through the introduction of highly efficient 12-inch wafer production lines.
