Abstract

A method of manufacturing a semiconductor device, comprises the steps of forming a first transfer pattern corresponding to a mask pattern on a major surface side of a semiconductor substrate through a first mask plate on which the first mask pattern having a straight portion and a bent portion is formed, and forming a second transfer pattern corresponding to a second mask pattern on a major surface side of the semiconductor substrate through a second mask plate on which the second mask pattern having a pattern arranged at a position corresponding to the straight portion is formed.
