摘要:
Halogen-containing polyacrylate derivatives having the formula: ##STR1## wherein A is a structural unit derived from a copolymeriazable monomer having a double bond; R is ##STR2## wherein each of R.sub.1 and R.sub.2 is a hydrogen atom or a fluorinated methyl group, provided R.sub.1 and R.sub.2 are not hydrogen atoms at the same time, and R.sub.3 is a hydrogen atom or a lower alkyl group; X is a halogen atom or a methyl group; and m is a positive integer, n is 0 or a positive integer, and n/m from 0 to 2, preferably from 0 to 1 are disclosed.Also disclosed are methods for forming a resist pattern by using the halogen-containing polyacrylate derivatives as a resist material.
