Abstract

PURPOSE:To enhance adhesion between a metallic thin film and a resist film and to prevent defects on a metal mask, by subjecting the metallic thin film deposited to a glass bustrate to heat treatment, and then, forming a photoresist film on this film. CONSTITUTION:Chromium is deposited on a glass substrate 3 by sputtering, vapor deposition, or the like method to form a chromium film 1. This film is heat-treated at 80-150 deg.C. Then, a photoresist film 4 is selectively formed in a specified pattern on the film 1 by the ordinary method, and the exposed parts of the film 1 are removed by etching using the film 4 as a mask, thus permitting a desired chromium thin film mask to be obtained after removing the remaining film 4.
