Paper Abstract

A novel approach to developer-soluble bottom anti-reflective coatings (BARCs) for 248-nm lithography was demonstrated. The BARC formulations are photosensitive, dye-filled systems incorporated with a polymer binder. The films are generated by thermally crosslinking the polymer matrix, and are then photochemically decrosslinked in order to render them soluble in developer solutions. The BARCs are compatible with solvents commonly used in the industry. Easy modification of the films with regard to optical properties for potential use with various substrates was also demonstrated. The BARCs exhibit anisotropic development in aqueous tetramethylammonium hydroxide (TMAH) solutions subsequent to simulated photoresist application, exposure, and post-exposure bake.
