Patent application numberDescriptionPublished
20090156007Polishing slurry and polishing method - The present invention relates to polishing slurry and polishing method used for polishing in a process for forming wirings of a semiconductor device, and the like. There are provided polishing slurry giving a polished surface having high flatness even if the polished surface is made of two or more substances, and further, capable of suppressing metal residue and scratches after polishing, and a method of chemical mechanical polishing using this. The polishing slurry of the present invention is polishing slurry containing at least one of a surfactant and an organic solvent, and a metal oxide dissolving agent and water, or polishing slurry containing water and abrasive of which surface has been modified with an alkyl group, and preferably, it further contains a metal oxidizer, water-soluble polymer, and metal inhibitor.06-18-2009
20100216309CMP POLISHING LIQUID AND METHOD FOR POLISHING SUBSTRATE USING THE SAME - Disclosed is a CMP polishing liquid for polishing a substrate having a layer containing ruthenium, comprising: an oxidizing agent; polishing particles; water; and a compound having a structure represented by the following Formula (1), or a salt thereof. This CMP liquid is improved in at least the polishing rate to a ruthenium layer when compared with conventional polishing liquid. Also disclosed is a method for polishing a substrate using such a CMP polishing liquid.08-26-2010
20110027997POLISHING LIQUID FOR CMP AND POLISHING METHOD - The present invention can provide a polishing liquid for CMP having good dispersion stability and a high polishing rate in polishing of interlayer insulating films and a polishing method. Disclosed a polishing liquid for CMP comprising: a medium; and colloidal silica particles dispersed in the medium, a blending amount of the colloidal silica particles being 2.0 to 8.0% by mass relative to 100% by mass of the polishing liquid, 02-03-2011
