  • Publication number: 20110274983
    Abstract: The present invention is directed to an electrolyte comprising a first phase including a porous organic microparticle; and a second phase including an ethylene oxide-containing polymer (i.e., an EOP); wherein the second phase is a continuous phase. The polymeric electrolyte compositions preferably also includes a lithium salt and optionally a solvent. The polymeric electrolyte composition may have a shear modulus, G?, measured at 1 rad/sec and about 30° C. and a conductivity, ?, measured at about 30° C., such that i) G?-? is greater than about 200 (S/cm)(dynes/cm2); and ii) G? is from about 104 to about 1010 dynes/cm2.

  • Patent number: 7316990
    Abstract: This invention relates to a high-strength herbicidal formulation containing high concentrations of glyphosate monomethylamine or dimethylamine salt and one or more surfactants selected to enhance the herbicidal activity of the glyphosate salts. The formulations exhibit significantly lower viscosity at high concentrations.

  • Patent number: 7066801
    Abstract: Provided is a method for manufacturing a fixed abrasive material suitable for use in CMP planarization pads from an aqueous polymer dispersion that also includes abrasive particles that involves frothing the polymer dispersion, applying the froth to a substrate, mold or carrier and curing the froth to form a fixed abrasive material having an open cell structure containing between about 5 and 85 wt % abrasive particles and a dry density of about 350 kg/m3 to 1200 kg/m3.

  • Patent number: 6918821
    Abstract: Provided are materials and methods for the chemical mechanical planarization of material layers using a down force of less than about 2.5 psi while maintaining a material removal rate generally similar to that obtained using higher down forces while simultaneously improving the selectivity of the process with respect to a primary material formed over a barrier material. The materials and methods disclosed herein are suitable for use in meatallization operations during semiconductor device fabrication, in particular in processes in which the primary material is a softer metal such as copper and the barrier material is a harder material such as a metal nitride.

  • Patent number: 6910951
    Abstract: Provided are materials and methods for the chemical mechanical planarization of material layers such as oxide or metal formed on semiconductor substrates during the manufacture of semiconductor devices using a fixed abrasive planarization pad having an open cell foam structure from which free abrasive particles are produced by conditioning and combined with a carrier liquid to form an in situ slurry on the polishing surface of the planarization pad that, in combination with relative motion between the semiconductor substrate and the planarization pad, tends to remove the material layer from the surface of the semiconductor substrate. Depending on the composition of the material layer, the rate of material removal from the semiconductor substrate may be controlled by manipulating the pH or the oxidizer content of the carrier liquid.

  • Patent number: 6849666
    Abstract: A process is disclosed for producing resilient polyurethane foams by foaming an organic polyisocyanate, an iso-cyanate-reactive compound and a fusible polymer. The improvement in the hardness of the foams is achieved without adversely affecting the other properties of the foams, such as tensile strength and elongation.
