Abstract
A dry-developing negative resist composition consisting of (a) a polymer of a monomer of the following formula I or II or a copolymer of a monomer of the following formula I with a monomer of the following formula II, ##STR1## in which R represents alkyl of 1 to 6 carbon atoms, benzyl, phenyl, or cyclohexyl and (b) 1% to 70% by weight, based on the weight of the composition, of a silicone compound. A negative resist pattern can be formed on a substrate by a process comprising coating the substrate with the resist composition, exposing the resist layer to an ionizing radiation, subjecting the resist layer to a relief treatment, and developing a resist pattern on the substrate by treatment with gas plasma.
