ABSTRACT:
A polysilicon layer is formed on a surface of a silicon substrate after oxygen ions are implanted into the silicon substrate and an SiO.sub.2 film is formed in the silicon substrate at a position in a prescribed depth from the surface of silicon substrate. A heat treatment is performed to a silicon layer between the polysilicon layer and the SiO.sub.2 film, thereby providing an SOI layer with improved crystal quality.
