20080314872 | Chemical-Mechanical Polishing Compositions Containing Aspartame And Methods Of Making And Using The Same - The present invention provides an aqueous CMP slurry composition that comprises abrasive particles and Aspartame. The CMP slurry composition according to the invention is selective for polishing silicon dioxide in preference to silicon nitride from a surface of an article by chemical mechanical planarization. Furthermore, as more Aspartame is added to the slurry, the silicon dioxide rate is either not greatly affected or increases and the silicon nitride rate stays extremely low. In addition to offering selectivity of silicon dioxide to silicon nitride polishing, the present invention provides a method of using Aspartame as a polish accelerant in silicon dioxide polishing. | 12-25-2008 |
20080286365 | Method For Producing Solid-Lipid Composite Drug Particles - A method of producing solid composite lipid/drug nanoparticles that includes the steps of: (1) dissolving a lipid and a drug in a suitable organic solvent to form a solution; (2) emulsifying the solution in a liquid to form an emulsion having a discontinuous phase of micelles comprising the organic solvent, the drug and the lipid, and a continuous phase comprising the liquid; and (3) contacting the emulsion with a supercritical fluid under conditions suitable to keep the supercritical fluid in a supercritical state, whereby the supercritical fluid extracts the organic solvent from the micelles, causing them to precipitate as organic-solvent free solid composite lipid/drug nanoparticles suspended or dispersed in the liquid. | 11-20-2008 |
20080274618 | POLISHING COMPOSITION AND METHOD FOR HIGH SELECTIVITY POLYSILICON CMP - The present invention provides a polishing composition and a method for removing polysilicon in preference to silicon dioxide, silicate glasses and/or silicon nitride via chemical-mechanical polishing during semiconductor device fabrication. In a preferred embodiment, the polishing composition includes an aqueous dispersion of ceria abrasive particles, from about 0.005% to about 0.15% by weight of a polyethyleneimine and a sufficient amount of an acid to adjust the pH of the polishing composition within the range of from about 4.7 to about 5.1. The polishing composition can be used to remove polysilicon via CMP at removal rates that are acceptable in semiconductor device fabrication applications while simultaneously suppressing the rate at which silicon dioxide, silicate glasses and silicon nitride are removed. | 11-06-2008 |
20080218935 | Ultra Low Temperature Fixed X7R And BX Dielectric Ceramic Composition And Method Of Making - Multilayer ceramic chip capacitors which satisfy X7R and BX requirements and which are compatible with silver-palladium internal electrodes are made in accordance with the invention. The capacitors exhibit desirable dielectric properties (high capacitance, low dissipation factor, high insulation resistance), excellent performance on highly accelerated life testing, and very good resistance to dielectric breakdown. The dielectric layers comprise a lead-free and cadmium-free barium titanate base material doped with other metal oxides such oxides of zinc, boron, bismuth, cerium, tungsten, copper, manganese, neodymium, niobium, silver, barium, silicon and nickel in various combinations. The dielectric ceramic materials herein can be sintered together (fired) at less than 1000° C. with an inner electrode having more than 80 wt % Ag and less than 20 wt % Pd to form a multilayer ceramic capacitor (MLCC). | 09-11-2008 |
20080202037 | AUTO-STOPPING SLURRIES FOR CHEMICAL-MECHANICAL POLISHING OF TOPOGRAPHIC DIELECTRIC SILICON DIOXIDE - The present invention provides auto-stopping CMP slurry compositions that minimize post-CMP non-uniformity and also extend the time that polishing can be continued beyond the end point without the risk of over-polishing the dielectric silicon dioxide film. Auto-stopping CMP slurry compositions according to the invention include ceria abrasive particles and an effective amount of a polyalkylamine such as polyethyleneimine dispersed in water. The methods of the invention include polishing a topographic dielectric silicon dioxide film layer using the auto-stopping CMP slurry compositions to obtain a dielectric silicon dioxide surface having a desired predetermined minimum step height. | 08-28-2008 |
