Abstract:
A method of manufacturing an electron device, comprising steps of:preparing a substrate on which a photoresist film is formed; preparing a mask, the mask providing a first and second phase shift pattern area on a mask plate, wherein the first phase shift pattern area contains a plurality of apertures formed in a resist light shielding area, and the second phase shift pattern area contains the same pattern as the first phase shift pattern, wherein a phase of the second phase shift pattern area is mutually inverse to that of the first phase shift area; transferring a pattern formed in the first phase shift pattern area onto a photoresist film formed on the substrate; and transferring a pattern formed in the second phase shift pattern area onto the photoresist film formed on the substrate in such a way that a pattern formed in the first phase shift pattern area is overlapped with a pattern formed in the first phase shift pattern area which is transferred onto a photoresist film formed on the substrate.
