In a method of manufacturing a semiconductor device including a wiring pattern in the form of a linear line having an intermediate portion with a locally different line width, the wiring pattern being formed by using a resist pattern, the resist pattern is formed through an exposure step using a mask pattern prepared by dividing the wiring pattern in a mask into a simple line portion and a rectangular pattern portion having a different line width, and interposing between the line portion and the rectangular pattern portion a slit having a predetermined separation width of not larger than 0.22xlambda/NA (lambda represents a wavelength of exposure light, and NA represents a numerical aperture of a projection lens). |
