Latest Patents
One of his notable inventions includes a trench gate type semiconductor device and the method of producing the same. This invention presents a method for creating a trench gate type MOSFET where each intersection trench is designed as a two-stage trench structure. In this process, the gate trench is backfilled with a mask material, which is then patterned to create a mask for forming each intersection trench. Importantly, the intersection trench intersects the gate trench at a deeper level, and a Schottky electrode is positioned at the base of each intersection trench. This method offers several advantages, such as a reduced cell pitch even when utilizing a wide bandgap semiconductor as the main substrate, facilitating the achievement of good ohmic contacts, and preventing excessive electric fields from impacting the insulating films at the bottom of each trench.
