A method of manufacturing a semiconductor device includes forming an insulating layer over a semiconductor region; forming a multilayer resist composite including a plurality of resist layers over the insulating layer; forming an opening in the resist layers of the multilayer resist composite except in the lowermost resist layer adjacent to the insulating layer; forming a reflow opening in the lowermost resist layer; reflowing part of the lowermost resist layer exposed in the reflow opening by heating to form a slope at the surface of the lowermost resist layer; forming a first gate opening in the lowermost resist layer so as to extend from the slope; and forming a gate electrode having a shape depending on the shapes of the opening in the multilayer resist composite, the slope and the first gate opening. |
