Patent ID: 7192645

Claim:
A co-polymer dielectric thin film prepared on a substrate by transport co-polymerization (“TCP”) of a first reactive intermediate with a second reactive intermediate, wherein the first reactive intermediate is formed from a first co-precursor, and wherein the second reactive intermediate is formed from a second co-precursor, the co-polymer dielectric thin film comprising: a co-Poly(Para-Xylylene) (“Co-PPX”) having repeating-units selected from the group consisting of ((—CH 2 —C 6 H 4 —H 2 C—) a (—CF 2 —C 6 H 4 —F 2 C—) b ) n oo , ((—CF 2 —C 6 F 4 —F 2 C—) a (—CH 2 C 6 F 4 —H 2 C—) b ) n oo , and ((—CF 2 —C 6 H 2 F 2 F 2 —C—) a (—CF 2 —C 6 F 4 —H 2 C—) b ) n oo , wherein, “a” is an integer that ranges from 3 to 10; “b” is an integer that ranges from 20 to 100; and n oo is an integer of at least 10; wherein the TCP is performed under a vacuum with a low system-leakage-rate, an inert atmosphere, or both; and wherein the film is at least semicrystalline.
