Abstract:
An insulating film layer is formed between a channel region of an MOS element formed in a monocrystal silicon layer of an SOS substrate in which the monocrystal silicon layer is laminated on a sapphire substrate, and the sapphire substrate, thereby to bring a stress state of the monocrystal silicon layer on the insulating film layer into a tensile stress state.
