Claim 0:
1. A method for providing a photoresist relief image comprising:
a) applying a coating layer of a photoresist composition on a substrate; and
b) exposing the photoresist composition layer to activating radiation and developing the exposed photoresist composition layer,
wherein: the photoresist composition comprises:
i) one or more polymers that comprise 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 comprises a tellurophene heterocycle and one or more ethylenically polymerizable groups, or
the tellurium-containing monomer is of Formula (IIIC); and

ii) one or more acid generator compounds, wherein,
R is hydrogen or an optionally substituted C1-16 alkyl;
S is a chemical bond or a chain having from 1 to 20 carbon and oxygen atoms that are optionally substituted;
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 of Formula (IIIC) further comprises one or more acid-cleavable groups.
