Latest Patents
One of his latest patents is focused on a semiconductor device and method of manufacturing the same. This invention includes a trench emitter electrode located at a boundary between one end of an active cell region and an inactive cell region. Additionally, it features a trench gate electrode positioned at the boundary between the other end of the active cell region and the inactive cell region. The design incorporates an end trench gate electrode connected to one end of the trench gate electrode and an end trench emitter electrode connected to one end of the trench emitter electrode. A hole barrier region of a first conductivity type is provided under a body region of a second conductivity type, strategically placed between the end trench gate electrode and the end trench emitter electrode in a plan view. Furthermore, a body region in the active cell region and a body region in the inactive cell region are interconnected by a body region situated between the end trench gate electrode and the end trench emitter electrode.
Another notable patent by Kuroda involves a built-in resistor that electrically connects a trench gate electrode and a gate pad. This resistor is formed of a conductive film that is applied on a semiconductor substrate via an insulating film. The film thickness of the insulating film is designed to be larger than that of the insulating film in a trench, yet smaller than that of the insulating film which serves as a field oxide film.
