    摘要: Method and apparatus are provided for polishing substrates comprising conductive and low k dielectric materials with reduced or minimum substrate surface damage and delamination. In one aspect, a method is provided for processing a substrate including positioning a substrate having a conductive material form thereon in a polishing apparatus having a rotational carrier head and a rotatable platen, wherein the substrate is disposed in the rotational carrier head and the platen has a polishing article disposed thereon, rotating the first carrier head at a first carrier head rotational rate and rotating a platen at a first platen rotational rate, contacting the substrate and the polishing article, accelerating the first carrier head rotational rate to a second carrier head rotational rate and accelerating the first platen rotational rate to a second platen rotational rate, and polishing the substrate at the second carrier head rotational rate and at the second platen rotational rate.

    摘要: A CMP method for polishing a phase change alloy on a substrate surface including positioning the substrate comprising a phase change alloy material on a platen containing a polishing pad and delivering a polishing slurry to the polishing pad. The polishing slurry includes colloidal particles with a particle size less than 60 nm, in an amount between 0.2% to about 10% by weight of slurry, a pH adjustor, a chelating agent, an oxidizing agent in an amount less than 1% by weight of slurry, and polyacrylic acid. The substrate on the platen is polished to remove a portion of the phase change alloy. A rinsing solution for rinsing the substrate on the platen includes deionized water and at least one component in the deionized water where the component selected from the group consisting of polyethylene imine, polyethylene glycol, polyacrylic amide, alcohol ethoxylates, polyacrylic acid, an azole containing compound, benzo-triazole, and combinations thereof.

    摘要: Methods and apparatuses are provided that remove a scrubber brush from contact with a wafer surface prior to slowing down the scrubber brush's rotational rate. The scrubbing method may include rotating a scrubber brush at a non-reduced rate, while the scrubber brush is in contact with the wafer and removing the scrubber brush from contact with the wafer while rotating the scrubber brush at the non-reduced rate. The scrubbing apparatus has a controller programmed to perform the scrubbing method.
