Abstract:
1. A method of improving on a patterned product wafer at least one of an etch resistance and a line-edge roughness of a photoresist layer having a surface, comprising: a) exposing the photoresist layer to a first process gas comprising either trimethyl aluminum (Al b) laser irradiating the photoresist layer and the first process gas to cause the first process gas to infuse into the photoresist layer, wherein the photoresist surface is raised to a temperature of between 300° C. and 500° C. with a temperature uniformity of +/−5° C.; c) removing remaining first process gas from a vicinity of the photoresist layer; d) exposing the photoresist layer to a second process gas comprising H e) laser irradiating the photoresist layer and second process gas to cause the H
