WATER REPELLENT ADDITIVE FOR IMMERSION RESIST |
摘要 |
<p>Disclosed is a water repellent additive for an immersion resist, which is composed of a fluorine-containing polymer that has a repeating unit represented by general formula (1). By adding the water repellent additive to a resist composition, the resist composition can be controlled to have high water repellency during exposure and to exhibit improved solubility in a developing solution during development. [In the formula, R1 represents a hydrogen atom, a fluorine atom, a methyl group or a trifluoromethyl group; R2 represents a heat-labile protecting group; R3 represents a fluorine atom or a fluorine-containing alkyl group; and W represents a divalent linking group.]</p> |
