Mitsubishi Electric Corporation has announced that its Power Device Works’ Fukuyama Factory has begun large-scale supply of power semiconductor chips. Specifically, these chips are products of its 12-inch silicon (Si) wafers for the assembly of semiconductor modules.

The advanced Si power-semiconductor modules will be of use in consumer products. Going forward, Mitsubishi Electric expects to contribute to green transformation (GX). Particularly, it will provide a stable and timely supply of semiconductor chips to meet the growing demand for energy-saving power-electronics devices in various applications.

The Fukuyama Factory processes wafers for the production of Si power-semiconductors. The factory is playing a key role in Mitsubishi Electric’s medium-term plan. Accordingly, it will double its wafer processing capacity for Si power- semiconductors by fiscal 2026 compared to five years earlier.

By supplying large quantities of 12-inch Si wafers for power semiconductor chips, the company will ensure stable production of advanced Si power-semiconductor modules. Thus, benefitting energy-saving power-electronics equipment applications.

Achieves Required Performance Levels

In August last year, Mitsubishi Electric Corporation announced the completion of the installation of its first 12-inch silicon wafer processing line at its Power Device Work’s Fukuyama Factory. Specifically, the plant manufactures power semiconductors. Also, the power semiconductor chips processed on this production line achieved the required performance levels.

As previously announced, Mitsubishi Electric is planning to start mass production on the new 12-inch silicon wafer line in FY2025. The company aims to approximately double its silicon power semiconductor wafer processing capacity by FY2026 compared to FY2021 levels.

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

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