Latest Patents

Kazuhisa Shibao holds a patent for a "Method of manufacturing semiconductor device." This invention aims to eliminate unwanted crystal defects generated by ion implantation. The process involves heat-treating a semiconductor substrate or an epitaxial layer in an inert gas atmosphere at temperatures ranging from 850°C to 1050°C to recrystallize the implanted region. Following this, the semiconductor substrate undergoes further heat treatment at 900°C to 1250°C in an oxygen-containing atmosphere. Additionally, to prevent abnormal growth of grain boundaries in a polycrystalline semiconductor layer deposited on an insulating film, the semiconductor layer is heat-treated at 900°C to 1100°C in an oxygen atmosphere. By integrating these processes into standard fabrication methods, semiconductor devices with high reliability, such as power MOSFETs, can be produced.
