With a total of two patents to his name, Higuchi's work has had a lasting impact on the industry.
Latest Patents
Higuchi's latest patents include an insulated gate static induction thyristor with a split gate type shorted structure. In this innovative design, the first gate of the split gate structure serves as a cathode short-circuit gate, while the cathode region is formed in the second gate. A MOS structure is created on the second gate, functioning as a control gate electrode that is isolated from the first gate. This design enhances channel integration density, leading to increased area efficiency. The MOS gate structure effectively suppresses the minority carrier (hole) storage effect, allowing for high-speed switching of the thyristor. Additionally, the shorted cathode structure improves the maximum controllable current and voltage durability. The split gate structure can be integrated with various configurations, including planar, buried, recessed, and double gate structures.
