Abstract:
1. A semiconductor device fabrication method comprising the step of forming a conducting film by CVD, so as to cover a first surface and a second surface of a silicon substrate, the second surface of the silicon substrate being a surface opposite to the first surface of the silicon substrate; the step of removing the conducting film at least in a first region of the first surface of the silicon substrate; and the step of forming a gate insulation film in the first region of the first surface of the silicon substrate, the semiconductor device fabrication method further comprising, after the step of forming the conducting film and before the step of forming the gate insulation film, the step of removing the conducting film over the second surface of the silicon substrate, in the step of forming the gate insulation film, the gate insulation film being formed with the second surface of the silicon substrate being exposed.
