Abstract:
An insulating film between stacked electrically conducting layers through which interconnections of integrated circuits are realized, is composed of an aerogel of an inorganic oxide on which organic monomers have been grafted under inert ion bombardment and successively further incorporated in the aerogel to fill at least partially the porosities of the inorganic aerogel. The composite dielectric material is thermally stable and has a satisfactory thermal budget. The method of forming an aerogel film includes the spinning of a precursor compound solution onto the wafer followed by supercritical solvent extraction carried out in the spinning chamber.
Abstract:
A process of final passivation of an integrated circuit device comprising at least one integrated circuit chip, comprising a step of formation of a layer of protective material (5) over a top surface of the at least one integrated circuit (3, 3', 3"), characterized in that said layer of protective material (5) comprises a High-Density Plasma Chemical Vapor Deposition (HDPCVD) and by providing for a subsequent step of planarization of said layer of protective material (5) to obtain a protection layer having a substantially flat top surface. (Figures 1 and 2).
