Abstract:
1. A method of manufacturing a MOSFET-type semiconductor device, the method comprising: forming a monocrystalline semiconductor layer in a shape of a wall on an insulating film; forming a gate electrode to be straddling over the semiconductor layer via an insulating film; forming source and drain regions on the semiconductor layer using the gate electrode as a mask; implanting carbon (C) at an oblique angle to one of the side walls of each of the source and drain regions; thermally oxidizing the side wall surfaces and then immersing them into an HF solution, to form a protective insulating film on the side wall surfaces to which C is applied; forming a first metal-semiconductor compound layer on the side wall surface of each of the source and drain regions, to which C is not applied, while maintaining the insulating film on the side wall surfaces to which C is applied; and forming a second metal-semiconductor compound layer having a different composition and Schottky barrier height with respect to the semiconductor layer from those of the first metal-semiconductor compound layer on the side wall of each source and drain regions to which C is applied after removing the side wall protective insulating film.
