Cyclic compound, process for production of the cyclic compound, radiation-sensitive composition, and method for formation of resist pattern
摘要:
A cyclic compound represented by formula (1): wherein L, R1, R′, and m are as defined in the specification. The cyclic compound of formula (1) is highly soluble to a safety solvent, highly sensitive, and capable of forming resist patterns with good profile. Therefore, the cyclic compound is useful as a component of a radiation-sensitive composition.
