Abstract

PURPOSE: To stabilize a schottky junction with a wiring pattern having a high density by controlling the exposure amount to a photo resist film provided on the stepped portion mounted on a semiconductor substrate.
CONSTITUTION: An insulation film 9 and 9' are mounted on a semiconductor substrate 8 and the film 9' is etched off to be changed into a thin gate insulation film 10 and 10'. Successively the film 10' on a source, drain region forming therein the substrate 8 and schottky junction is etched off to mount thereon a metallic film 11 of Al and others. Thereafter, the full surface is covered with a photoresist film 12, in this case a film 14 to 14' on a stepped portion 13 to 13' is made thin than that a film 16 on a planer portion 15. Successively, when the resist film 12 is exposured, the thin film 11 is caused to associate with the stepped portion 13 to be separated the exposure amount is given changeably to the remaining stepped portion 13' and 13" and the planer portion 15 to make the film a pattern configuration 17. Thereafter, the film is etched as used for a mask, a thin film 14 is made a deter mined wiring pattern 18 to generate a schottky junction 19.
