ABSTRACT:
Structured resists are consolidated, that is post-exposure amplified. The amplifying agent used is a compound which contains at least one bicyclic or polycyclic group. The amplifying agent is attached via a reactive group to a reactive anchor group of a polymer that is used for the resist. The process is particularly suitable for amplifying copolymers of cycloolefins and maleic anhydride.
