ROHM and Toshiba agree to collaborate in manufacturing power devices

A plan by ROHM (“ROHM”) and Toshiba Electronic Devices & Storage
(“Toshiba Electronic Devices & Storage”) to collaborate in the
manufacture and increased volume production of power devices has been
recognized and will be supported by the Ministry of Economy, Trade and Industry as
a measure supporting the Japanese Government’s target of secure and stable
semiconductor supply. ROHM and Toshiba Electronic Devices & Storage will
respectively make intensive investments in silicon carbide (SiC) and silicon (Si)
power devices, effectively enhance their supply capabilities, and complementally
utilize other party’s production capacity

Power devices are essential components for supplying and managing power supply in
all kinds of electronic equipment, and for achieving a carbon-free, carbon-neutral
society. Current demand is expected to see continued growth. In automotive
applications, development of more efficient, smaller and lighter electric powertrains has
advanced alongside the rapid expansion in vehicle electrification. In industrial
applications, stable supply of power devices and improved characteristics are widely
required to support increasing automation and higher efficiency requirements.

Against this backdrop, ROHM has formulated a management vision, “We focus on
power and analog solutions and solve social problems by contributing to our customers’
needs for energy savings and miniaturization of their products.,”
and accelerates its
efforts for a carbon-free. SiC power devices are the keys to energy savings. Since the
world’s first mass production of SiC MOSFETs, ROHM has been constantly developing technologies. Among these are ROHM’s latest 4th Generation SiC
MOSFETs that will be adopted for numerous electric vehicles and industrial equipment.
As one of its priority projects, ROHM is working on SiC business, which contains
aggressive and continuous investment to increase the production capacity of SiC and
meet strong demand growth.

Toshiba, with its long-standing Basic Commitment, “Committed to People,
Committed to the Future.,”
aims to advance the achievement of carbon neutrality and
a circular economy. Toshiba Electronic Devices & Storage has for decades supplied Si
power devices, mainly for automotive and industrial markets, that have helped to
secure energy saving solutions and equipment miniaturization. The company started
production on a 300mm wafer line last year, and is accelerating investment to enhance
production capacity and meet strong demand growth. It is also advancing development
of a wider lineup of SiC power devices, especially for automotive and power
transmission and distribution applications, taking full advantage of the expertise it has
cultivated in railway vehicle applications

ROHM has already announced its participation in the privatization of Toshiba, but this
investment did not serve as the starting point for manufacturing collaboration between
the two companies. Under intensifying international competition in the semiconductor
industry, ROHM and Toshiba Electronic Devices & Storage have been considering
collaboration in the power device business for some time, and that resulted in the joint

ROHM and Toshiba Electronic Devices & Storage will collaborate in manufacturing
power devices, through intensive investments in SiC and Si power devices,
respectively, toward enhancing both companies’ international competitiveness. The
companies will also seek to contribute to strengthening the resilience of semiconductor
supply chains in Japan.
