    Abstract: An apparatus and method for sequential application of cleaning fluids for improved maintenance of chemical mechanical polishing (CMP) systems is disclosed. A method includes transferring a first substrate to a first polishing station of a plurality of polishing stations, polishing the first substrate at the first polishing station, transferring the first substrate to a second polishing station, and transferring a second substrate to the first polishing station. The method includes cleaning a first surface of a plurality of surfaces of the polishing system by dispensing a first cleaning fluid from a first one or more nozzles of a plurality of nozzles to direct the first cleaning fluid onto the first surface and dispensing a second cleaning fluid from the first one or more nozzles to direct the second cleaning fluid onto the first surface, where the second cleaning fluid is different from the first cleaning fluid.

    Abstract: Embodiments of the present disclosure generally provide methods, polishing systems with computer readable medium having the methods stored thereon, to facilitate consistent tensioning of a polishing article disposed on a web-based polishing system. In one embodiment, a substrate processing method includes winding a used portion of a polishing article onto a take-up roll of a polishing system by rotating a first spindle having the take-up roll disposed thereon; measuring, using an encoder wheel, a polishing article advancement length of the used portion of the polishing article wound onto the take-up roll; determining a tensioning torque to apply to a supply roll using the measured polishing article advancement length; and tensioning the polishing article by applying the tensioning torque to the supply roll.

    Abstract: A bushing assembly for supporting a substrate within a processing chamber is generally provided. In one aspect, the bushing assembly comprises a tubular body having an outer perimeter and an aperture extending therethrough, a first ring having a first inner edge, the first ring disposed in the aperture in an upper portion of the tubular body, and a second ring having a second inner edge, the second ring disposed in the aperture in a lower portion of the tubular body. In another aspect, the first inner edge has a first radius of curvature, and the second inner edge has a second radius of curvature. In another aspect, a first inner edge diameter, a second inner edge diameter, the first radius of curvature, and the second radius of curvature are selected such that a support pin extending through the aperture contacts the bushing assembly on at most two points.

    Abstract: A method and apparatus for determining a polishing pad thickness profile are described herein. A set of displacement sensors, including an arm displacement sensor and one or more conditioning disk displacement sensors are utilized to determine the orientation of a conditioning disk and the thickness of the polishing pad. The displacement sensors are non-contact sensors, such as a laser sensor, a capacitive sensor, or an inductive sensor. Once the thickness profile of the polishing pad is determined, one or more process conditions is altered to improve substrate polishing.
