Mitsubishi Electric buys stake in Novel Crystal Technology
Tokyo-based Mitsubishi Electric Corp has taken an equity position in Novel Crystal Technology Inc of Saitama, Japan, which develops and sells gallium oxide wafers. Gallium oxide (β-Ga2O3) is a promising candidate for use in superior energy-saving power semiconductors that Mitsubishi Electric intends to develop at an accelerated pace in support of global decarbonization.
As one of the first companies to develop, manufacture and sell gallium oxide wafers for power semiconductors, Novel Crystal Technology has manufacturing technology that Mitsubishi Electric will use in its production of gallium oxide power semiconductors.
Mitsubishi Electric say that it has been contributing to energy saving in power electronic products by producing semiconductors made of silicon and silicon carbide (SiC). Recent advances have been achieved with silicon carbide and gallium nitride wafers, but gallium oxide wafers are expected to help achieve even higher breakdown voltages and lower power dissipation.
Mitsubishi Electric now expects to accelerate its development of gallium oxide power semiconductors by combining its own expertise in the design and manufacture of low-energy-loss, high-reliability power semiconductors with Novel Crystal Technology's expertise in the production of gallium oxide wafers.
