There are contained the steps of forming an undoped or low impurity concentration amorphous silicon film to project from an upper surface of a first insulating film, introducing selectively impurity into an uppermost surface of the amorphous silicon film to form the uppermost surface of
A method for fabricating a semiconductor device includes the steps of depositing an amorphous silicon layer on a substrate, and forming an oxidation film on a surface of the amorphous silicon layer by treating the surface of the amorphous silicon layer with an oxidation gas. The forming
