Known Application
This product is primarily used as a photoacid generator (PAG) in chemically amplified photoresist systems for advanced semiconductor lithography. Upon exposure to UV or deep ultraviolet (DUV) light, it generates strong acids that initiate catalytic deprotection reactions in photoresist materials, enabling high-resolution pattern formation.
Typical applications include :
Semiconductor photoresist formulations
Integrated circuit (IC) manufacturing
Advanced lithography processes (DUV / ArF)
Microelectronic and nanofabrication technologies
Chemically amplified resist (CAR) systems
Advanced packaging applications
Electronic and optoelectronic materials
This type of sulfonium salt PAG is widely used due to its high acid generation efficiency, good thermal stability, and suitability for advanced-node lithography processes requiring high resolution and low line-edge roughness.
