    摘要: Fluorine-free photoacid generators and photoresist compositions containing fluorine-free photoacid generators are enabled as alternatives to PFOS/PFAS photoacid generator-containing photoresists. The photoacid generators are characterized by the presence of a fluorine-free heteroaromatic sulfonate anionic component. The photoacid generators preferably contain an onium cationic component, more preferably a sulfonium cationic component. The photoresist compositions preferably contain an acid sensitive imaging polymer. The compositions are especially useful for forming material patterns using 193 nm (ArF) imaging radiation.
