Latest Patents

Hara's latest patents focus on methods of manufacturing semiconductor devices that enhance the yield of IGBTs. These techniques are designed to reduce steady loss, turn-off time, and turn-off loss. The process involves the formation of openings in an interlayer insulating film on a substrate's main surface. The etching of a laminated insulating film, which includes a PSG film, an SOG film, and a silicon oxide film, is temporarily halted at a silicon nitride film. Subsequently, both the silicon nitride film and the silicon oxide film are etched sequentially to create the openings. This innovative approach prevents the openings from penetrating through an n-type source layer and a p-type emitter layer, which have a thickness of 20 to 100 nm, thus safeguarding the substrate.
