Photopatterned product of silicone polyamic acid on a transparent substrate

摘要

Photopatternable silicone polyamic acid can be spun onto a substrate and thereafter used in combination with a photoresist as an antireflective coating or as a patterned silicone polyimide. The silicone polyamic acid can be used with an absorbing dye, or it can be tinted with an organic dye to provide color filters when applied on a transparent substrate.
