发明名称 Photosensitive coating for enhancing a contrast of a photolithographic exposure
摘要 A photosensitive coating material for enhancing a contrast of a photolithographic exposure of a resist film formed on a substrate, including a base polymer, a solvent for facilitating deposition of the photosensitive coating material upon a surface adjacent to said resist film to form a film thereupon, an alkaline additive suited to diffuse into the adjacent resist for reducing or neutralizing an acid concentration formed locally therein, a photoactive component arranged to reduce or neutralize a concentration of the alkaline additives in portions of the photosensitive coating, which are exposed with optical light, UV- or X-ray radiation, electrons, charged particles, ion projection lithography.
