Latest Patents

Inoue's latest patents include a power semiconductor device that features a unique design with a first terminal (source terminal) and a second terminal (drain terminal). The substrate main surface of the semiconductor chip is oriented in a specific direction, while the main contact face of an n-type region and a p-type region is perpendicular to this face. The device incorporates elongated n-type and p-type regions arranged alternately to form a voltage holding area. The first terminal connects to the p-type regions through wiring, and the second terminal connects to the n-type regions. Additionally, the p-type region is designed to cover the bottom corners of a gate polycrystalline silicon layer.

Another notable patent involves the vapor phase growth on semiconductor wafers. This process is executed using an apparatus that holds multiple semiconductor wafers vertically, allowing them to rotate together. The wafers are placed in a heater within a reaction vessel, equipped with both raw material gas supply and exhaust nozzles. As the temperature of the heater rises, raw material gas flows horizontally across each wafer, resulting in a uniform layer growth from the gas.
