Abstract: A reticle for use in exposing a semiconductor capable of increasing the contrast of a resist pattern to be formed on a wafer through exposure without involvement of a change in the geometry of a diaphragm plate even when a circuit pattern formed on a reticle becomes more minute; a method of producing the reticle; and a semiconductor device. The irregularities 11 are formed in the glass surface 12 of the halftone reticle 10, thus enabling uniform diffusion of the illumination light 15 over the glass surface 12. Consequently, the oblique incident light 20 effective for improving the contrast of an image to be formed on the wafer 112 can be readily and inexpensively increased without involvement of complicated processes. Even when the hole pattern 14 becomes minute, the contrast of a resist pattern to be radiated on the wafer 112 can be improved.

Abstract: Disclosed herein is how to obtain the magnitude of focus deviation and the direction of the deviation directly from a focus measuring mark. The magnitude of focus deviation is measured from the length of the focus measuring mark (3) in the elongate direction. The length of a tapered part (20) of the focus measuring mark (3) in which the resist gradually becomes thinner is measured from the secondary electron signal waveform of a scanning electron microscope. The direction of the focus deviation is obtained from the measured length of the tapered part (20).
