Abstract:
A chemically amplified photoresist composition comprising: a photosensitive polymer represented by formula (1) ##STR9## and a photoacid generator in a range from about 1% to about 15% by weight based on the weight of the photosensitive polymer, whereinR.sub.1 is hydrogen, --OH, --COOH, or aliphatic hydrocarbon having a C.sub.1 -C.sub.20 polar functional group,R.sub.2 is a t-butyl group, a tetrahydropyranyl group or a 1-alkoxyethyl group,l, m and n are integers, l/(l+m+n) equals 0.0 to 0.4, m/(l+m+n) equals 0.5, n/(l+m+n) equals 0.1 to 0.5, andthe weight average molecular weight of the polymer is in the range of 3,000 to 100,000.
