Paper Abstract

We have developed novel acrylic copolymers for ArF photoresist which have more etching durability than usual. The excellent one of those copolymers in handling contains 8- or 9- methacryloyloxy-4-oxatricyclo[,6]decan-3-one (OTDMA) and (gamma) ,(gamma) -dimethyl-(alpha) -methylene-(gamma) -butyrolac tone (DMMB). OTDMA is a new methacrylic ester monomer having a lactone unit with bridged structure. DMMB introduces a lactone structure to the main chain of acrylic copolymers. It was suggested that the solubility of monomers depends on the hindrance of their polar group, and the role of the hydrophilic monomers has been discussed from the standpoint of the position of their hydrophilic parts.
