Toshiba, ROHM and Mitsubishi Electric Explore Semiconductor Integration
Japanese chipmakers enter early-stage talks to combine operations and strengthen global competitiveness in power semiconductors.
Japan’s Toshiba, ROHM, and Mitsubishi Electric have signed a memorandum of understanding (MoU) to begin discussions on potentially combining parts of their semiconductor operations.
The proposed collaboration would involve integrating the semiconductor activities of Toshiba’s subsidiary, Toshiba Electronic Devices & Storage Corporation, alongside ROHM’s chip business and Mitsubishi Electric’s power device division.
This move reflects a wider push by Japanese manufacturers to strengthen their competitiveness in the global semiconductor market. Toshiba and ROHM have already been exploring cooperation in power devices, and the addition of Mitsubishi Electric is expected to expand both technological capabilities and operational scale.
All parties involved, including investment partners backing Toshiba, have agreed to proceed with exploratory talks. The objective is to create a more competitive business structure with greater technological depth, capable of serving a diverse range of industries and customers worldwide.
If the integration goes ahead, it could enhance efficiency and reinforce Japan’s position in the power semiconductor sector—an area that plays a vital role in electric vehicles, industrial systems and energy management.
At present, discussions remain at an early stage, with details around structure, investment and timelines yet to be determined.
