    Abstract: A polishing apparatus comprises a dresser that can adjust swing speed in the scanning areas set on a polishing member along a swing direction, a height detection section that measures a surface height of the polishing member in a plurality of monitoring areas set on the polishing member along the swing direction of the dresser, a dress model matrix creation section that creates a dress model matrix defined from a plurality of monitoring areas, scanning areas and a dress model, an evaluation index creation section that calculates a height profile predicted value using the dress model, the swing speed in each scanning area or a staying time and sets evaluation index based on a difference from a target value of height profile of the polishing member and a moving speed calculation section that calculates the swing speed in each scanning area of the dresser based on the evaluation index.

    Abstract: Implementations of the present disclosure generally relate to planarization of surfaces on substrates and on layers formed on substrates, including an apparatus for in-situ temperature control during polishing, and methods of using the same. More specifically, implementations of the present disclosure relate to in-situ temperature control with a condensed gas during a chemical-mechanical polishing (CMP) process. In one implementation, the method comprises polishing one or more substrates against a polishing surface in the presence of a polishing fluid during a polishing process to remove a portion of a material formed on the one or more substrates. A temperature of the polishing surface is monitored during the polishing process. Carbon dioxide snow is delivered to the polishing surface in response to the monitored temperature to maintain the temperature of the polishing surface at a target value during the polishing process.

    Abstract: The invention suppresses generation of noises attributable to rotation of a rotary joint. A rotary joint includes a rotating body that rotates on a rotating axis A, a housing disposed so as to surround the rotating body, and at least one bearing disposed between the rotating body and the housing and adapted to support rotation of the rotating body. The rotary joint supplies fluids through fluid connection ports formed in the housing and fluid passages formed inside the rotating body to a polishing table having attached thereto a polishing pad for polishing a substrate or a holding portion that is adapted to hold the substrate while pressing the substrate against the polishing pad. At least one elastic member is interposed at least either between the rotating body and the at least one bearing or between the housing and the at least one bearing.

    Abstract: A polishing apparatus includes a table rotating motor configured to rotate a polishing table about its own axis, a top ring rotating motor configured to rotate a top ring about its own axis, a dresser configured to dress a polishing pad, and a pad-height measuring device configured to measure a height of the polishing pad. The polishing apparatus also includes a diagnostic device configured to calculate an amount of wear of the polishing pad from the height of the polishing pad and to determine the end of a life of the polishing pad based on the amount of the wear of the polishing pad, the torque or current of the table rotating motor, and the torque or current of the top ring rotating motor.
