Patent ID: 7341816

Claim:
A method for forming a photoresist composition having a desired dissolution rate comprising: determining a first exo mole percent of a polycyclic olefin monomer having a fluorinated carbinol pendent group as represented by Formula A: where m is an integer from 0 to 5; and Z represents -(CH 2 ) p -, where p is equal to 1 or 2; and where at least one of R 1 to R 4 is, independently, a fluorinated carbinol pendent group having from 1 to 20 carbon atoms, each carbon atom, independently, being substituted with 1, 2, or 3 fluorine atoms and where the oxygen atom is protected by a blocking or protective group that is acid cleavable; forming a first polymer comprising repeating units derived from said polycyclic olefin monomer; determining a first dissolution rate of said polymer; modifying the first exo mole percent of said polycyclic olefin monomer to a second exo mole percent greater than or less than the first exo mole percent; forming a second polymer comprising repeating units derived from the polycyclic olefin monomer having the second exo mole percent; and formulating the photoresist composition, such composition comprising the second polymer.
