Power semiconductor materials from Japan

NCT was established in 2015. The founding investors were Tamura Corporation, an electronics parts manufacturer, and domestic researchers who had been studying gallium oxide. The idea of using this material as a semiconductor was conceived by Japanese researchers, and Japan is leading the way in practical applications.

Gallium oxide was originally researched as a substrate for light-emitting diodes (LEDs). In 2008, Tamura Corporation acquired Mitsunami, an optoelectronics company that had been developing gallium oxide LED substrates, and began researching this material. He recalls, "As I was working with the material, I began to think that it might have promising applications as a power semiconductor.
