Abstract:
A process for forming an integrated circuit comprising:(a) positioning a layer of a dielectric composition, said dielectric composition comprising a decomposable polymer and an organic polysilica, said decomposable polymer having a three-dimensional star architecture, said decomposable polymer prepared by reacting a polyfunctional compound having at least three hydroxyfunctional groups with a cyclic ester wherein a star polymer having at least three arms is formed, on a substrate;(b) heating said composition to condense said polysilica;(c) decomposing said decomposable polymer;(d) lithographically patterning said dielectric layer;(e) depositing a metallic film onto said patterned dielectric layer; and(f) planarizing said metallic film to form an integrated circuit.
