PROBLEM TO BE SOLVED: To provide a radiation sensitive resin composition having high transparency to radiation, excellent in basic physical properties as a resist, e.g. sensitivity, resolution and pattern shape, excellent also in shelf stability as a composition and retaining satisfactory adhesiveness to a substrate. SOLUTION: The radiation sensitive resin composition contains (A) a low molecular compound obtained by preparing a compound having one or more amino groups with at least one hydrogen atom bonding to a nitrogen atom and substituting a t-butoxycarbonyl group for one or more of such hydrogen atoms bonding to a nitrogen atom, (B) a radiation sensitive acid generating agent and (C) an alkali-insoluble or slightly alkali-soluble acid dissociable group- containing resin having an alicyclic structure in the principal chain and/or a side chain and a carboxylic acid anhydride structure in a side chain and convertible to an alkali-soluble resin when the acid dissociable group is dissociated. |
