    摘要: Polishing compositions and methods for removing conductive materials and barrier materials from a substrate surface are provided. Polishing compositions are provided for removing at least a barrier material from a substrate surface by a chemical mechanical polishing process or by an electrochemical mechanical polishing process. The polishing compositions used in barrier removal may further be used after a process for electrochemical mechanical planarization process of a conductive material. The polishing compositions and methods described herein improve the effective removal rate of materials from the substrate surface with a reduction in planarization type defects.

    摘要: Methods and apparatus for processing substrates to improve polishing uniformity, improve planarization, remove residual material and minimize defect formation are provided. In one aspect, a method is provided for processing a substrate having a conductive material and a low dielectric constant material disposed thereon including polishing a substrate at a polishing pressures of about 2 psi or less and at platen rotational speeds of about 200 cps or greater. The polishing process may use an abrasive-containing polishing composition having up to about 1 wt. % of abrasives. The polishing process may be integrated into a multi-step polishing process.
