Abstract:
1. A resist patterning process comprising: coating a chemically amplified resist composition onto a photomask blank having a chromium compound film at an outermost surface, and heating the chemically amplified resist composition to eliminate an excessive solvent component remaining in the coated film, to obtain a resist film; conducting pattern exposure on the resist film by high energy radiation; and developing the resist film with a developer, wherein the chemically amplified resist composition comprises one or more kinds of amine compounds at least having: a carboxyl group; no hydrogen atoms covalently bonded to a nitrogen atom as a basic center; and no nitrogen atoms as part of an aromatic ring, and wherein the amine compound having a carboxyl group and no hydrogen atoms covalently bonded to a nitrogen atom as a basic center is an amine compound represented by the following general formula (1): wherein R R R R
