Abstract:
A method of manufacturing a semiconductor device, the method comprising the steps of:preparing a substrate composed of a supporting substrate, a dielectric film and a single crystal silicon (Si) layer; forming a first opening section in the single crystal Si layer at a position around a gate electrode forming region; embedding an interlayer dielectric film in the first opening section; forming a second opening section in the single crystal Si layer at a position around a gate electrode forming region; forming a gate electrode in the second opening section; forming a gate dielectric film on the gate electrode; forming an epitaxial silicon (Si) layer on the gate dielectric film; forming a body region in the epitaxial Si layer; forming a diffusion layer for source/drain regions in the epitaxial Si layer located on both sides of the body region; and forming a body terminal on the body region for applying a specified potential to the body region.
