Abstract:
A process for forming an integrated circuit device comprising:(a) positioning a layer of a dielectric composition comprising a silsesquioxane and a photosensitive amine generator, said amine generator selected from the group consisting of carbamate derivatives derived from substituted o-nitrobenzyl alcohols and mono- or diisocyanates urethanes, benzyl carbamates, benzyl sulfonamides, benzyl quaternary ammonium salts, imines, iminium salts, cobalt-amine complexes, (.alpha.-methyl-2-nitrobenzyloxycarbonyl) carbamates of primary or secondary amines, diamines or polyamines and compounds having the formula RR'--N--COOR"", where R and R' are independently hydrido or C.sub.1 -C.sub.6 alkyl and R"" is nitrobenzyl or .alpha.-methylnitrobenzyl, on a substrate;(b) generating amine from said photosensitive amine generator;(c) heating said dielectric composition to react said silsesquioxane whereby a dielectric layer is formed on said substrate;(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.
