[0002] TAIC is the abbreviation of crosslinking agent, the crosslinking agent is also called bridging agent, and is an important component of polyhydrocarbon photoresist. Photochemical curing of the photoresist depends on participation of the crosslinking agent with double photosensitive functional groups in the reaction. After exposure, the crosslinking agent generates double free radicals, which interact with the polyhydrocarbon resin to form a bridge between the polymer molecular chains, and become insoluble three-dimensional structure.
