ABSTRACT:
A pattern forming material includes a binary copolymer represented by the following general formula or a ternary or higher copolymer obtained by further polymerizing the binary copolymer with another group: ##STR1## wherein R.sub.1 indicates a hydrogen atom or an alkyl group; R.sub.2 and R.sub.3 independently indicate a hydrogen atom, an alkyl group, a phenyl group or an alkenyl group or together indicate a cyclic alkyl group, a cyclic alkenyl group, a cyclic alkyl group having a phenyl group or a cyclic alkenyl group having a phenyl group; R.sub.4 indicates a hydrogen atom or an alkyl group; x satisfies a relationship of 0<x<1; and y satisfies a relationship of 0<y<1.
