Claim 13:
14. A photoresist composition, comprising:
one or more polymers comprising repeating units formed by the polymerization of a tellurium-containing monomer: wherein the tellurium containing monomer
repeating units formed by the polymerization of a tellurium-containing monomer: wherein the tellurium containing monomer that comprises a tellurophene heterocycle and one or more ethylenically polymerizable groups, or
the tellurium-containing monomer is of Formula (IIIC); and
one or more acid generator compounds,, wherein,
R is hydrogen or an optionally substituted C1-16 alkyl;
S is a linker;
each R1 is the same or different non-hydrogen substituent;
R2 is a non-hydrogen substituent; and
n is an integer of 0 to 4;
wherein the tellurium-containing monomer represented by the formula (IIIC) comprises one or more acid-cleavable groups.
