Abstract:
A method of manufacturing a semiconductor device, including providing a semiconductor wafer, forming a photoresist film on a main surface of the semiconductor wafer, forming a first mask pattern and a second mask pattern on the photoresist film, selectively removing portions of the photoresist film according to the first and second mask patterns, to respectively form a first opening and a second opening in the photoresist film, a position of the second opening differing from that of the first opening, and performing ion implantation of an impurity into the semiconductor wafer, using the photoresist film having the first and second openings formed therein as a mask.

Claim (Index 15):
The method according to  claim 14 , wherein\n the semiconductor wafer is of a first conductivity type, the first semiconductor element is an insulated gate bipolar transistor, the second semiconductor element is a diode, forming the first semiconductor element and the second semiconductor element includes forming, in a surface layer at the main surface of the semiconductor wafer, a semiconductor region of a second conductivity type, which constitutes an anode region of the diode and a base region of the insulated gate bipolar transistor, and performing the ion implantation includes implanting the impurity from the main surface of the semiconductor wafer near an interface between the semiconductor wafer and the semiconductor region of the second conductivity type.
