WebOur photo acid generator product line has proven quality and performance for excimer resist applications with industry leading resist manufactures. Besides the products listed below, We are developing diazodisulfones and triphenylsulfonium salts. Also, we sell diphenyliodonium compounds which are used as optical cationic initiators (WPI series). Photoacids are molecules which become more acidic upon absorption of light. Either the light causes a photodissociation to produce a strong acid or the light causes photoassociation (such as a ring forming reaction) that leads to an increased acidity and dissociation of a proton. There are two main types of molecules that release protons upon illumination: photoacid generators (PAGs) and photoacids (PAHs). PAGs undergo proton photodissociation irreversibly, …
