Latest Patents

Yoshida's latest patents include a semiconductor device and a method of manufacturing the same. In his first patent, a gate electrode is formed inside a trench via a gate insulating film. The process involves removing the gate insulating film formed on a semiconductor substrate, followed by the formation of an insulating film on the substrate. A p-type base region is created in the semiconductor substrate, along with an n-type emitter region in the base region. A hydrogen annealing process is then performed on the substrate, ensuring that the boundary between the base and emitter regions is positioned deeper than the insulating film. His second patent details a method of manufacturing a semiconductor device, where a first MISFET is formed on a semiconductor layer of an SOI substrate in a circuit region, and a second MISFET is created for TEG inspection. This process includes forming an interlayer insulating film, creating contact holes, and forming plugs in those holes, with specific connections to the semiconductor substrate.
