Abstract:
1. A method for manufacturing a semiconductor device, the method comprising: applying a photoresist to a substrate, the photoresist comprising a resin and a cross-linking agent, the resin comprising a plurality of polymers, each one of the plurality of polymers comprising a backbone; exposing the photoresist to a patterned energy, the patterned energy inducing a reaction to form a bond between a backbone of a first one of the plurality of polymers and a backbone of a second one of the plurality of polymers; and developing the photoresist after the exposing the photoresist, the developing being performed with a negative tone developer, wherein the cross-linking agent has a structure of wherein n can be from between 1 to 15, A and B comprise H, OH, halide, an aromatic carbon ring, or a straight or cyclic alkyl, alkoxyl/fluoro, alkyl/fluoroalkoxyl chain having a carbon number of between 1 and 12, and X and Y comprise —NH 2 , —SH, —OH, isopropyl alcohol, isopropyl amine, or a thiol.
