SPIN CASTABLE RESIST COMPOSITION AND USE THEREOF

摘要

Spin castable polymethylmethacrylate photoresist compositions are provided utilizing certain cinnamic acid derivatives as dyes capable of absorbing light at about 436 nm and substantially transparent to light at about 220-250 nm. The spin castable polymethylmethacrylate resist compositions are used in making semiconductor devices by multilayer photoresist methods.
