Latest Patents

Hisayoshi Yanai holds a patent for a voltage-controlled type semiconductor switching device. This device includes a pair of controlled electrodes that receive a control voltage signal. A semiconductive layer is formed between the electrodes, which is electrically insulative from them through insulative layers. The semiconductive layer features a channel region and a carrier-storage region that is substantially nonconductive. The channel region is designed to allow majority carriers, such as electrons, to flow laterally along the electrodes. In the current cut-off mode, the carrier-storage region temporarily stores carriers that move due to the electric field created by the voltage. Conversely, in the current conduction mode, the carrier-storage region releases the stored carriers toward the channel region.
