Abstract: A method for manufacturing a semiconductor device is provided. In the method, an amorphous silicon film is deposited in a recess provided in a surface of a substrate by supplying a silicon-containing gas to the substrate. The amorphous silicon film is etched by supplying an etching gas to the substrate so as to leave the amorphous silicon film on a bottom of the recess. A silicon film is deposited on the amorphous silicon film by supplying dichlorosilane to the substrate.

The depression penetrating the insulating film is configured so as to extend to the semiconductor substrate. The method includes: forming a thin film of a semiconductor material along a wall surface that defines the depression; annealing the workpiece to cause the semiconductor material of the thin film to move toward a bottom of the depression and to form an epitaxial region corresponding to crystals of the semiconductor substrate; and etching the thin film.
