A production method of a semiconductor device which includes the steps of exposing a resist coated on a substrate of a semiconductor device by projecting a first light pattern on the substrate of the semiconductor device the first light pattern being formed by passing light through a first mask, and exposing the resist by projecting a second light pattern on the substrate, the second light pattern being formed by passing light through a second mask. In the step of exposing the resist by projecting the second light pattern, the second light pattern is formed by excimer laser light having an annular shape and passed through the second mask.
