The present invention provides polishing pads for use in CMP processes. In one embodiment, a pad comprises a surface defining a plurality of grooves with landing surfaces separating the grooves, the landing surfaces together defining a substantially coplanar polishing surface, each groove having a depth of at least about 10 mil and a width, WG, with any two adjacent grooves being separated from each other a landing surface having a width, WL, wherein the quotient WL/WG is less than or equal to 3. In a preferred embodiment, the surface of the pad defines a series of concentric substantially circular grooves. In an alternative embodiment, the surface of the pad defines a spiral groove having a depth of at least about 10 mil and a width WG, and a spiral landing surface outlining spiral groove the having a width, WL, wherein the spiral landing surface defines a substantially coplanar polishing surface and the quotient WL/WG is less than or equal to 3.
摘要:
The present invention provides chemical-mechanical polishing (CMP) compositions and methods for polishing an ITO surface. The compositions of the invention comprise a particulate zirconium oxide or colloidal silica abrasive, which has a mean particle size of not more than about 150 nm, suspended in an aqueous carrier, which preferably has a pH of not more than about 5. Preferably, the abrasive has a surface area in the range of about 40 to about 220 m2/g. The CMP compositions of the invention provide an acceptably low surface roughness when used to polish an ITO surface, providing clean and uniform surfaces.
摘要:
The invention provides a method of polishing a substrate comprising (i) contacting a substrate with a polishing system comprising (a) an abrasive, a polishing pad, a means for oxidizing a substrate, or any combination thereof, (b) a conducting polymer having an electrical conductivity of about 10−10 S/cm to about 106 S/cm, and (c) a liquid carrier, and (ii) abrading or removing at least a portion of the substrate to polish the substrate.
