Paper Abstract

Alkaline soluble maleimide based tetrapolymers which were prepared by free radical copolymerization are found to be suitable for use as non-imaginable resists in multilevel photolithographic processing. These materials offer widely variable undercut rates because of the ability to vary the composition during free radical polymerization and show little or no scumming when used in lift-off resist. This new polymer system may also be used as the base soluble resin in a photoresist formulation or a base soluble antiflective coating composition as well as used in making lift-off resists.
