Patent ID: 8921031

Claim:
A photoresist overcoat composition, comprising: a polymer comprising as polymerized units a monomer of the following general formula (I): wherein: R 1 is chosen from hydrogen and substituted or unsubstituted C1 to C3 alkyl; R 2 is chosen from substituted and unsubstituted C1 to C15 alkyl; X is oxygen, sulfur or is represented by the formula NR 3 , wherein R 3 is chosen from hydrogen and substituted and unsubstituted C1 to C10 alkyl; and Z is a single bond or a spacer unit chosen from optionally substituted aliphatic and aromatic hydrocarbons, and combinations thereof, optionally with one or more linking moiety chosen from —O—, —S—, —COO— and —CONR 4 — wherein R 4 is chosen from hydrogen and substituted and unsubstituted C1 to C10 alkyl; wherein the polymer is free of silicon and fluorine; an organic solvent; and a basic quencher; wherein the photoresist overcoat composition is free of acid generator compounds and wherein the basic quencher has a higher surface free energy than that of the polymer.
