Patent ID: 7026052

Claim:
A dielectric thin film prepared on a substrate, the dielectric thin film comprising: a polymer material formed by homo-transport polymerization (“HTP”) of radical intermediates, the radical intermediates being formed from a first precursor, and the radical intermediates having a general structure (II): wherein: X 1 and X 2 are similar or different, and individually a hydrogen, a fluorine, an alkyl group, a fluorinated alkyl group, a phenyl group, or a fluorinated phenyl; Ar is an aromatic or a fluorinated-aromatic group moiety; n o comprises an integer of at least 2, but is less than total sp 2 carbons on the aromatic moiety; and e comprises a free radical having an unpaired electron; and a second precursor incorporated into the polymer material, wherein the second precursor is removable from the dielectric film to create a porous dielectric film, wherein the second precursor comprises a general structure of (I): wherein each Y is a leaving group selected from —COOR, NR 2 , and halides, wherein R is an alkyl group.
