| titleOfInvention | Polymers blends and their use in photoresist compositions for microlithography |
| abstract | A photoresist composition having (A) at least two polymers selected from the group consisting of: (a) a fluorine-containing copolymer comprising a repeat unit derived from at least one ethylenically unsaturated compound characterized in that at least one ethylenically unsaturated compound is polycyclic; (b) a branched polymer containing protected acid groups, said polymer comprising one or more branch segment(s) chemically linked along a linear backbone segment; (c) fluoropolymers having at least one fluoroalcohol group having the structure:-C(Rf)(Rf')OH wherein Rf and Rf' are the same or different fluoroalkyl groups of from 1 to about 10 carbon atoms or taken together are (CF2)n wherein n is 2 to 10;(d) amorphous vinyl homopolymers of perfluoro(2,2-dimethyl-1,3-dioxole) or CX2=CY2 where X = F or CF3 and Y = H or amorphous vinyl copolymers of perfluoro(2,2-dimethyl-1,3-dioxole) and CX2 = CY2; and (e) nitrile/fluoroalcohol-containing polymers prepared from substituted or unsubstituted vinyl ethers; and (B) at least one photoactive component. |
