Abstract: 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 light pattern on the substrate of the semiconductor device, developing the resist exposed by the light pattern to form a wafer pattern with the resist, and etching the substrate on which the wafer pattern with the resist is formed. In the step of exposing the light pattern is formed by illuminating a mask with excimer laser light having an annular shape.

Abstract: 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 light pattern on the substrate of the semiconductor device through an object lens, developing the resist exposed by the light pattern to form a wafer pattern with the resist, and etching the substrate on which the wafer pattern with the resist is formed.
