Title:

CURABLE COMPOSITION AND METHOD FOR PRODUCING CURABLE FILM

Document Type and Number:

WIPO Patent Application WO/2014/034671

Kind Code:

A1

Abstract:

　Provided is a curable composition with which it is possible to obtain a low dielectric constant curable film which, while maintaining water repellency, exhibits lipophilic properties which enable the application of an organic solvent-based coating solution, and which has adequate insulating properties. Also provided is a method for producing a curable film using said curable composition, and a semiconductor element using a cured film obtained by curing said curable composition.　This curable composition contains: (A) a fluorine-containing polyarylene prepolymer having a crosslinkable functional group; (B) a compound having a number average molecular weight of 140 to 3,000 and which does not contain fluorine atoms, but has two or more crosslinkable functional groups; (C) a compound having a number average molecular weight exceeding 3,000 but not exceeding 50,000, not containing fluorine atoms, having a C6-24 alkyl group and a crosslinkable functional group, and in which ether-type oxygen atoms may be present between carbon atoms; and (D) a radical polymerization initiator.
