Antireflective coating compositions
摘要:
Antireflective compositions are provided that contain an ionic thermal acid generator material. Use of such a thermal acid generator material can significantly increase the shelf life of solutions of antireflective compositions in protic media. Antireflective compositions of the invention can be effectively used at a variety of wavelengths used to expose an overcoated photoresist layer, including 248 nm and 193 nm.
