Abstract

Amorphously crosslinked aromatic polymeric low .kappa. materials and methods for their fabrication are provided. The subject materials are prepared by a modified transport polymerization process, in which aromatic precursors are pyrolyzed to produce radical comprising aromatic monomeric precursors which are then allowed to polymerize by deposition onto a substrate surface, where during and/or after deposition the growing polymer chain is exposed to a high energy crosslinking agent, such as high energy photons or plasma. The subject crosslinked materials find use in a variety of applications, particularly as low .kappa. dielectrics in the manufacture of integrated circuits.
