Paper Abstract

A new silyl ether of resorcinol novolak resin (SERN) and a new photoactive compound (S-55NQ) have been developed for a bilayer resist system. The SERN resin is an addition-condensation type terpolymer from resorcinol, hexamethylenetetramine, and phenyl silyl ether (PSE), which is a reaction product of resorcinol and chlorosilane, under acid catalyzed condition. The S-55NQ sensitizer is a sulfonate ester of spiroglycol and naphthoquinone diazide. This alkaline soluble Si-containing resist, useful in the mid-UV region, shows high dry etching resistance to O2 plasma and O2 RIE. An etching rate ratio of 4.5 or higher based on HPR-204 as the bottom layer is obtained.
