Abstract
A simple mathematical model has been employed to analyze quantitativel y the crosslinking process in chemically amplified negative resists ba sed on the combination of an epoxidized novolac resin and a photoacid generator. Experimental evaluation of a number of resists employing di fferent resins has shown that sensitivity and contrast increase concom itantly. A resist formulation based on an experimental Dow resin desig nated DQ9 has demonstrated exceptional contrast and a sensitivity well matched to many e-beam systems.
