Abstract:
A polymer film prepared from a method comprising:co-polymerizing an intermediate (A) and an intermediate (B); wherein, intermediate (A) and intermediate (B) are co-polymerized at a feed rate onto a substrate having a substrate temperature under vacuum or inert atmosphere with a slow system leakage rate, the substrate temperature being below a melting temperature of the intermediate (A); the intermediate (A) is an aromatic compound consisting of nâ€² reactive sites with nâ€² unpaired electrons and nâ€² is an integer of at least 2 but is smaller than, or equal to, the maximum number of sites for the sp2C substitution in the intermediate (A) the intermediate (B) is a bridging compound consisting of nâ€³ reactive sites with nâ€³ unpaired electrons; and nâ€³ is an integer of at least 2 but is smaller than, or equal to, the maximum number of sites for the sp3C substitution in the intermediate (B); and the polymer film has a thermal stable crystalline form suitable for use as a dielectric thin film in fabrication of an integrated circuit.
