    Abstract: A pattern formation method, comprising: (a) providing a semiconductor substrate; (b) forming a photoresist pattern over the semiconductor substrate, wherein the photoresist pattern is formed from a photoresist composition comprising: a first polymer comprising acid labile groups; and a photoacid generator; (c) coating a pattern overcoat composition over the photoresist pattern, wherein the pattern overcoat composition comprises a second polymer and an organic solvent, wherein the organic solvent comprises one or more ester solvents, wherein the ester solvent is of the formula R1—C(O)O—R2, wherein R1 is a C3-C6 alkyl group and R2 is a C5-C10 alkyl group; (d) baking the coated photoresist pattern; and (e) rinsing the coated photoresist pattern with a rinsing agent to remove the second polymer. The methods find particular applicability in the manufacture of semiconductor devices.

    Abstract: Photoresist topcoat compositions, comprising: a first polymer comprising a first repeat unit of general formula (I) and a second repeat unit of general formula (II): wherein: R1 independently represents H, F or optionally fluorinated C1 to C4 alkyl; R2 represents optionally fluorinated linear, branched or cyclic C1 to C20 alkyl; L1 represents a single bond or a multivalent linking group; and n is an integer of from 1 to 5; a second polymer comprising a first repeat unit of general formula (III) and a second repeat unit of general formula (IV): wherein: R3 independently represents H, F or optionally fluorinated C1 to C4 alkyl; R4 represents linear, branched or cyclic C1 to C20 alkyl; R5 represents linear, branched or cyclic C1 to C20 fluoroalkyl; L2 represents a single bond or a multivalent linking group; and n is an integer of from 1 to 5; and a solvent. Coated substrates coated with the described topcoat compositions and methods of processing a photoresist composition are also provided. The invention finds particular applicability in the manufacture of semiconductor devices.
