摘要:
Photoacid generators generate sulfonic acids of formula (1a) or (1c) upon exposure to high-energy radiation. R1—COOCH(CF3)CF2SO3−H+ (1a) R1—O—COOCH(CF3)CF2SO3−H+ (1c) R1 is a C20-C50 hydrocarbon group having a steroid structure. The photoacid generators are compatible with resins and can control acid diffusion and are thus suited for use in chemically amplified resist compositions.
摘要:
Sulfonate salts have the formula:CF3—CH(OCOR)—CF2SO3−M+ wherein R is C1-C20 alkyl or C6-C14 aryl, and M+ is a lithium, sodium, potassium, ammonium or tetramethylammonium ion. Onium salts, oximesulfonates and sulfonyloxyimides and other compounds derived from these sulfonate salts are effective photoacid generators in chemically amplified resist compositions.

Sulfonate salts have the formula: R1SO3—CH(Rf)—CF2SO3−M+ wherein R1 is alkyl or aryl, Rf is H or trifluoromethyl, and M+ is a Li, Na, K, ammonium or tetramethylammonium ion. Onium salts, oximesulfonates and sulfonyloxyimides and other compounds derived from these sulfonate salts are effective photoacid generators in chemically amplified resist compositions.
