| Use Pattern |
| Core Function: Photoacid Generator (PAG) |
| It absorbs light and undergoes photolytic cleavage |
| Produces a strong acid (difluoromethanesulfonic acid) The generated acid can catalyze chemically amplified reactions or initiate subsequent cationic polymerization. It is a key functional additive in photoresist and cationic photopolymer curing systems. II. Main Application Areas 1.Semiconductor Photoresists (Chemically Amplified Photoresists, CARs) Applicable to: i-line, KrF, and ArF lithography systems High-resolution chemically amplified photoresists Main functions: Acid generation upon exposure Catalyzes deprotection reactions Amplifies exposure effects → improves resolution, sensitivity, and critical dimension / line edge roughness (CD/LER) control Advantages of the adamantyl structure: Provides high thermal stability Reduces acid diffusion → improves resolution and line edge roughness Enhances optical performance and formulation stability of photoresists Cationic Photocuring Systems Used in UV-induced cationic curing of epoxy resins and vinyl ether materials UV irradiation → acid generation → initiates cationic ring-opening polymerization or crosslinking Applications include: UV-curable coatings and inks Electronic encapsulation materials Photo-patternable insulating layers (e.g., PSPI, PI) |
