Abstract: A method for selective electroplating of a semiconductor input/output (I/O) pad includes forming a titanium-tungsten (TiW) layer over a passivation layer on a semiconductor substrate, the TiW layer further extending into an opening formed in the passivation layer for exposing the I/O pad, such that the TiW layer covers sidewalls of the opening and a top surface of the I/O pad. A seed layer is formed over the TiW layer, and portions of the seed layer are selectively removed such that remaining seed layer material corresponds to a desired location of interconnect metallurgy for the I/O pad. At least one metal layer is electroplated over the remaining seed layer material, using the TiW layer as a conductive electroplating medium.

Abstract: A fusible link for a semiconductor device comprises an insulating substrate and a conductive line pair on the surface of the insulating substrate, with the conductive line pair having spaced ends. A polymer is disposed over the insulating substrate and between the conductive line pair ends. The polymer is capable of being changed from a non-conductive to a conductive state upon exposure to an energy beam. Preferably, the polymer comprises a polyimide, more preferably, a polymer/onium salt mixture, most preferably, a polyaniline polymer doped with a triphenylsufonium salt. The link may further comprise a low &kgr; nanopore/nanofoam dielectric material adjacent the conductive line ends.

Abstract: The present invention provides a method of preventing the build-up of polishing material within low areas of a substrate during polishing. Following the blanket deposition of a first layer, a selectively removable material is deposited over the first layer, wherein the selectively removable material fills the low areas. A surface of the substrate is polished removing the excess first layer and selectively removable material from the surface, leaving the first layer and selectively removable material within the low area. Following polishing, the selectively removable material is removed from the low areas prior to the deposition of a second layer.

Abstract: A multi-chip module is constructed by aligning prewired chips on a support wafer and depositing a nonconductive thermally conductive and electrically nonconductive material having a coefficient of thermal expansion that approximate that of the chips (e.g. silicon, silicon carbide, silicon germanium, germanium or SiCGe) to surround chips. After removal of the support wafer, processing of multi-chip module is finished with wiring on a shared surface of multi-chip module and chip surface.

Abstract: A process for producing a plurality of metallized vias in a polyimide dielectric is disclosed. The process includes depositing a polyimide precursor, then a silane and finally a metal, after patterning the polyimide and silane. The sandwich is heated to completely imidize the polyimide, crosslink the silane and anneal the metal simultaneously. The excess metal overlying the polyimide between the vias is removed by chemical mechanical polishing using the crosslinked silane as a polish stop.

Abstract: A process is disclosed for forming multilayered polyimide structure from negative photosensitive polyimide precursors. An initial polyimide layer is deposited and imagewise exposed. The unexposed portions of the initial polyimide layer are inhibited and then a second polyimide layer is deposited and likewise imagewise exposed. The films are developed, thereby forming a multilayer polyimide structure. After formation of the multilayer polyimide structure, a conductive material is applied on a substrate and then the polyimide layers are lifted off thereby forming a desired pattern of metallization.

Abstract: A semiconductor fabrication process for forming borderless contacts (130, 170, 172) using a removable mandrel (110). The process involves depositing a mandrel on an underlying barrier layer (100) designed to protect underlying structures (40) formed on a substrate (24). The mandrel is made from a material that will etch at a faster rate than the barrier layer so as to permit the formation of openings in the mandrel to be stopped on the barrier layer without penetrating such layer. After depositing a contact (130) in a first opening (120) formed in the mandrel, a second opening (140) is formed and a second contact (170) is deposited therein. Thereafter, the mandrel is removed and replaced with a layer of solid dielectric material (180).

Abstract: Thermostable compounds are prepared by mixing perylene dianhydride with one or more aminosilanes in a molar ratio of 1:4 in an inert solvent, and the aminosilanes may comprise aminoalkylakoxysilanes. Upon heating the mixture a thermostable coating is formed. Prior to heating the mixture may be spin-applied to a substrate. The coating may be used in semiconductor device fabrication as the mixture has good spin-on characteristics with the cured compound being thermally stable over 600.degree. C. and having good etch characteristics.
