Abstract
PURPOSE:To improve lift-off performance and to facilitate other processes, by using a conventional method once to perform exposure/development of a sample substrate and next by using the same photomask to perform exposure/ development of the sample substrate again. CONSTITUTION:A light-interrupting part 13 is formed on a rear side of a photo mask 12 disposed a prescribed length above a sample substrate 10. When ultraviolet light 14 is radiated from above, a diffraction phenomenon occurs at an edge part of the light-interrupting part 13 so as to emit diffracted light 15. A resist layer on the substrate 10 is exposed by this diffracted light 15 and the ultraviolet light 14. Subsequently an unexposed part 11a remains by developing the substrate 10. When the substrate 10 is exposed similarly by the abovementioned exposure process, a tapered part 16 produced by a first exposure/ development process is exposed directly by the diffracted light 15. When the substrate is developed afterwards, the tapered part 16 is removed and a resist layer 11b remains with its edge formed perpendicularly.
