Abstract:
A method of fabricating a semiconductor device, comprising:forming a first layer on a substrate; forming a second layer on said first layer; forming a recess from which said first layer is exposed by removing a part of said second layer; forming an insulating film covering a surface of said second layer, and an inner wall face and a bottom face of said recess; forming a mask by depositing a material different than said insulating film onto said insulating film from a direction which forms a predetermined angle with a direction of a normal line of a surface of said insulating film; performing anisotropic etching on said insulating film exposed from said mask from the direction of a normal line of a surface of said mask, to expose a part of the first layer; removing said mask; and forming a gate electrode on the first layer exposed in the recess.
