A semiconductor device includes a Si substrate, an insulating film formed on one part of the Si substrate, a bulk Si region grown on other part of the Si substrate other than the insulating film, Si1-xGex(0<x≦̸1) thin film formed on the insulating film in direct contact with the insulating film, and substantially flush with top of the bulk Si region, a first field effect transistor fabricated in the bulk Si region, and a second field effect transistor fabricated in the Si1-xGex thin film.
