Mitsubishi Electric invests in Novel Crystal Technology to boost energy-saving power semiconductor development

Mitsubishi Electric Corporation has taken an equity position in Novel Crystal Technology, Inc., a pioneering developer and seller of gallium-oxide wafers. The partnership aims to expedite the development of high-efficiency, energy-saving power semiconductors, reinforcing Mitsubishi Electric’s commitment to supporting global decarbonization.

Novel Crystal Technology stands as one of the first companies worldwide to develop, manufacture, and sell gallium-oxide wafers for power semiconductors. The firm’s manufacturing prowess is a key attribute that Mitsubishi Electric seeks to integrate into its own production of gallium-oxide power semiconductors.

Historically, Mitsubishi Electric has made significant strides in reducing energy consumption in power-electronic products through the production of silicon and silicon carbide (SiC) semiconductors. However, recent advancements in SiC and gallium-nitride wafers have paled in comparison to the potential of gallium-oxide wafers, which are expected to yield even higher breakdown voltages and lower power dissipation.

Through its equity position in Novel Crystal Technology, Mitsubishi Electric plans to leverage the company’s gallium-oxide wafer production expertise, thereby accelerating the development of its superior energy-saving gallium-oxide power semiconductors. This strategic partnership merges Mitsubishi Electric’s proficiency in designing and manufacturing low-energy-loss, high-reliability power semiconductors with Novel Crystal Technology’s gallium-oxide wafer production capabilities, signifying a significant step towards a more sustainable future.
