Abstract:
A method for improving the wettability of a substrate, the method comprising:contacting the substrate with an aqueous solution comprising about 10 ppm to about 10,000 ppm of at least one surfactant having the formula (I) or (II): wherein R1 and R4 are a straight or a branched alkyl chain having from 3 to 10 carbon atoms; R2 and R3 are either H or an alkyl chain having from 1 to 5 carbon atoms; and m, n, p, and q are numbers that range from 0 to 20;coating the substrate with a resist coating to provide a resist-coated substrate; exposing at least a portion of the resist-coated substrate to a radiation source for a time sufficient to provide a pattern on the resist coating; and applying an aqueous developer solution to the substrate to dissolve at least a portion of the resist coating wherein the contacting step is conducted prior to the applying step.
