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.
