    摘要: Apparatus and methods for conditioning a polishing pad in a CMP system are provided. In one embodiment, a method includes performing a pre-polish process including urging a conditioner disk against a polishing surface of a polishing pad disposed in a polishing station, moving the conditioner disk relative to the polishing pad in a sweep pattern across the polishing surface while monitoring a rotational force value required to move the conditioner disk relative to the polishing pad, determining a metric indicative of an interaction between the conditioner disk and the polishing surface from the rotational force value, adjusting a polishing recipe in response to the metric, and polishing one or more substrates using the adjusted polishing recipe.

    摘要: Polishing pads used in CMP machines are consumable components that are typically replaced after a specific number of wafers have been processed. The life of a polishing pad is optimized by controlling the rate of material removal from the polishing pad by the conditioning disk. The conditioning disk removes enough material so the polishing surface can properly process the wafers but does not remove any excess material. Preventing excess material removal extends the life of the polishing pad. During CMP processing, the controller receives data concerning the torque applied to the conditioning disk and the torque applied to the arm to sweep the conditioning disk across the polishing pad. Based upon the detected operating conditions, the system can predict the rate of material removal and adjust the forces applied to the conditioning disk so that the life of the polishing pad is optimized.

    摘要: Embodiments of the present invention generally relate to methods for chemical mechanical polishing a substrate. The methods generally include measuring the thickness of a polishing pad having grooves or other slurry transport features on a polishing surface. Once the depth of the grooves on the polishing surface is determined, a flow rate of a polishing slurry is adjusted in response to the determined groove depth. A predetermined number of substrates are polished on the polishing surface. The method can then optionally be repeated.

    摘要: A chemical mechanical polishing apparatus includes a metrology system that detects the thickness of the polishing pad as semiconductor wafers are processed and the thickness of the polishing pad is reduced. The chemical mechanical polishing apparatus includes a controller that adjusts the rate of material removal of a conditioning disk when areas of the polishing surface are detected that are higher or lower than the adjacent areas of the polishing pad.
