摘要:A production method of a semiconductor device which includes the steps ofexposing 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 beingformed by passing light through a first mask, and exposing the resist by projecting asecond light pattern on the substrate, the second light pattern being formed by passinglight through a second mask. In the step of exposing the resist by projecting the secondlight pattern, the second light pattern is formed by excimer laser light having an annularshape and passed through the second mask.
