Chemical mechanical polishing slurry for metal layers and films

Abstract: A polishing slurry for chemically mechanically polishing metal layers and films during the various stages of multilevel interconnect fabrication associated with integrated circuit manufacturing. The slurry includes an aqueous medium, an abrasive, an oxidizing agent, and an organic acid. The polishing slurry has been found to significantly lower or inhibit the silicon dioxide polishing rate, thus yielding enhanced selectivity. In addition, the polishing slurry is useful in providing effective polishing to metal layers at desired polishing rates while minimizing surface imperfections and defects. Also disclosed is a method for producing coplanar metal/insulator films on a substrate utilizing the slurry of the present invention and chemical mechanical polishing technique relating thereto.

Organically modified aerogels, processes for their preparation by surface modification of the aqueous gel, without prior solvent exchange, and subsequent drying, and their use

Abstract: The present invention relates to novel, organically modified aerogels, uses thereof, and a process for producing them in which a) a hydrogel is introduced as an initial charge, b) the hydrogel obtained in step a) is subjected to surface modification, and c) the surface-modified gel obtained in step b) is dried. The present invention additionally relates to novel, organically modified wet gels, to a process for producing them, and to their use.

Printable electrical conductors

Abstract: An electrical conductor formed from one or more metallic inks. The electrical conductor comprises a network of interconnected metallic nodes. Each node comprises a metallic composition, e.g., one or more metals or alloys. The network defines a plurality of pores having an average pore volume of less than about 10,000,000 nm3. The electrical conductors advantageously have a high degree of conductivity, e.g., a resistivity of not greater than about 10x the resistivity of the (bulk) metallic composition, which forms the individual nodes.

Controlling ink migration during the formation of printable electronic features

Abstract: Processes for controlling ink migration during the formation of printable electronic features. In a preferred aspect, the invention is to a process for forming at least a portion of an electronic feature. The process includes the steps of: (a) providing a first substrate having a first surface; (b) modifying the first surface to form a modified surface; and (c) applying an ink to at least a portion of the modified surface, wherein the modified surface interacts with the ink to inhibit lateral and/or longitudinal migration of the applied ink, and wherein the applied ink forms at least a portion of the electronic feature. In another aspect, the invention is to a process for encouraging electronic ink spreading with a surfactant.

Production of metal nanoparticles

Abstract: Processes for the production of metal nanoparticles. In one aspect, the invention is to a process comprising the steps of mixing a heated first solution comprising a base and/or a reducing agent (e.g., a non-polyol reducing agent), a polyol, and a polymer of vinyl pyrrolidone with a second solution comprising a metal precursor that is capable of being reduced to a metal by the polyol. In another aspect, the invention is to a process that includes the steps of heating a powder of a polymer of vinyl pyrrolidone; forming a first solution comprising the powder and a polyol; and mixing the first solution with a second solution comprising a metal precursor capable of being reduced to a metal by the polyol.
