Abstract

A pellicle is proposed in which the agglutinant layer which enables the pellicle to adhere to a photomask is doped with a de-foaming agent which depends on a reactive fluorine-modified silicone oil for its anti-foaming performance, and typically such reactive fluorine-modified silicone oil has a vinyl group at both ends of its molecular chain.
