Known Application

This product is primarily used as a photoacid generator (PAG) in chemically amplified photoresist systems for advanced semiconductor lithography. Upon UV or deep ultraviolet (DUV) exposure, it generates strong acids that catalyze deprotection reactions in photoresists, enabling high-resolution pattern formation and improved lithographic performance.

Typical applications include:
Semiconductor photoresist formulations
Integrated circuit (IC) manufacturing
DUV lithography processes
Microelectronic and nanofabrication technologies
Chemically amplified resist (CAR) systems
Advanced packaging and electronic materials

As a sulfonium salt-based PAG, it offers high acid generation efficiency, good thermal stability, and suitability for high-resolution lithographic patterning.
