Abstract:
A polymer for use in a chemically amplified photoresist and represented by the following formula: ##STR16## where R' is one selected from the group consisting of: ##STR17## in which R.sub.1 is one selected from the group consisting of --H and --CH.sub.3, and m and n are integers, m/(m+n)=0.1-0.6, and ##STR18## where R.sub.2 is one selected from the group consisting of --H and --CH.sub.3, R.sub.3 is one selected from the group consisting of --H and --CH.sub.3, R.sub.4 is one selected from the group consisting of --H, --CH.sub.3 and --CH.sub.2 CH.sub.2 OH, p, q and r are integers, p/(p+q+r)=0.1 to 0.7, q/(p+q+r)=0.1 to 0.7, and r/(p+q+r)=0.1 to 0.5.
