Abstract:
1. A process rinse solution to reduce pattern collapse defects on the surface of a substrate having a photoresist that has been patterned and developed, the solution consisting of at least one carrier medium selected from the group consisting of an aqueous solvent or a non-aqueous solvent and 10 ppm to about 10,000 ppm of at least one surfactant selected from the group of surfactants having the formula, (IVa), or (VIII): wherein R 1 and R 4 are each independently a straight or a branched alkyl group having from 3 to 10 carbon atoms; R 2 and R 3 are each independently a hydrogen atom or an alkyl group having from 1 to 5 carbon atoms; R 5 is a straight or a branched alkyl group having from 1 to 10 carbon atoms; R 6 is a straight or a branched alkyl group having from 4 to 16 carbon atoms; R 7 , R 8 , and R 9 are each independently a straight or a branched alkyl group having from 1 to 6 carbon atoms; R 10 is a hydrogen atom or a group represented by the formula R 11 is a straight, a branched, or a cyclic alkyl group having from 4 to 22 carbon atoms; W is a hydrogen atom or an alkynyl group; X and Y are each independently a hydrogen atom or a hydroxyl group; Z is a halide atom, a hydroxyl group, an acetate group, or a carboxylate group; m and n are each independently a number that ranges from 0 to 20; r and s are each independently 2 or 3; t is a number that ranges from 0 to 2; j is a number that ranges from 1 to 5; and x is a number that ranges from 1 to 6.
