Claim 11:
12. The method of claim 1, wherein the acid-labile group containing monomer of the second polymer has the structure of formula (7), wherein in formula (7), Rb is hydrogen, fluorine, a substituted or unsubstituted C1-5 alkyl, or a substituted or unsubstituted C1-5 fluoroalkyl; each A is independently a halogen, a hydroxy, a carboxylic acid or ester, a thiol, a straight chain or branched C1-20 alkyl, a monocyclic or polycyclic C3-20 cycloalkyl, a monocyclic or polycyclic C3-20 fluorocycloalkenyl, a monocyclic or polycyclic C3-20 heterocycloalkyl, a monocyclic or polycyclic C6-20 aryl, or a monocyclic or polycyclic C4-20 heteroaryl, each of which is substituted or unsubstituted; and m is independently an integer of 0 to 4;
wherein in formula (7), R11, R10, and R8 are each independently hydrogen, a straight chain or branched C1-20 alkyl, a straight chain or branched C1-20 heteroalkyl, a monocyclic or polycyclic C3-20 cycloalkyl, a monocyclic or polycyclic C3-20 heterocycloalkyl, a monocyclic or polycyclic C6-20 aryl, a C7-20 aryloxyalkyl, or a monocyclic or polycyclic C4-20 heteroaryl, each of which is substituted or unsubstituted and wherein any two of R11, R10, and R8 together optionally may form a ring;
wherein in formula (7), R7 is hydrogen, a substituted or unsubstituted straight chain or branched C1-20 alkyl, a substituted or unsubstituted monocyclic or polycyclic C3-20 cycloalkyl, a substituted or unsubstituted monocyclic or polycyclic C3-20 heterocycloalkyl, a substituted or unsubstituted C6-14 aryl, a substituted or unsubstituted C3-14 heteroaryl, a substituted or unsubstituted C7-18 arylalkyl, a substituted or unsubstituted C4-18 heteroarylalkyl, or a substituted or unsubstituted C1-12 heteroalkyl; and wherein in formula (7), R9 is hydrogen, a substituted or unsubstituted straight chain or branched C1-20 alkyl, a substituted or unsubstituted monocyclic or polycyclic C3-20 cycloalkyl, a substituted or unsubstituted monocyclic or polycyclic C3-20 heterocycloalkyl, a substituted or unsubstituted C6-14 aryl, a substituted or unsubstituted C3-14 heteroaryl, a substituted or unsubstituted C7-18 arylalkyl, a substituted or unsubstituted C4-18 heteroarylalkyl, or a substituted or unsubstituted C1-12 heteroalkyl; and
wherein R7 and R9 can join together to form a ring, and any one of R7, R9 can join together with any of R8, R10 or R11 to form a ring.
