摘要:
A novel ester compound having an alkylcycloalkyl or alkylcycloalkenyl group as the protective group is provided as well as a polymer comprising units of the ester compound. The polymer is used as a base resin to formulate a resist composition having a higher sensitivity, resolution and etching resistance than conventional resist compositions.
