  • Resist materials and related processes
    Patent number: 5741629
    Abstract: Polymers suitable for chemically amplified resists based on styrene chemistry are advantageously formed with a meta substituent on the phenyl ring of the styrene moiety. Additionally, polymers for such applications including, but not limited to, meta substituted polymers are advantageously formed by reacting a first monomer having a first protective group with a second monomer having a second protective group. After polymerization, the second protective group is removed without substantially affecting the first protective group. For example, if the first protective group is an alkoxy carbonyl group, and the second protective group is a silyl ether group, treatment with a lower alcohol with trace amounts of acid transforms the silyl group into an OH-moiety without affecting the alkoxy carbonyl group.
