Abstract

Glass photomasks having a high resolution stain pattern for use in photofabrication processes are made by migrating stain-producing ions into the surface of a glass substrate, and reducing and agglomerating the stain- producing ions in the presence of pure hydrogen under pressure at relatively low temperatures to produce a high resolution stain pattern. <IMAGE>
