    摘要: A dressing apparatus 200 includes a bus member 203 which is equipped with a ceiling plate 201 and a circular or polygonal cylindrical skirt portion 202 provided at a bottom surface of the ceiling plate 201 and which is configured to accommodate a polishing pad 131 from thereabove. The bus member 203 includes a dual fluid nozzle 204 configured to jet a cleaning liquid and a gas onto a polishing surface of the polishing pad 131; a dress board 205 configured to come into contact with the polishing surface of the polishing pad 131; and a rinse nozzle 206 configured to supply a rinse liquid onto a contact surface between the polishing surface of the polishing pad 131 and the dress board 205. A cleaning liquid, a fragment of a grindstone or a sludge is suppressed from being scattered around by the skirt portion 202.

    摘要: 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.

    摘要: A polishing apparatus polishes a surface of a substrate by pressing the substrate against a polishing pad on a polishing table. The polishing apparatus is configured to control a temperature of the polishing surface of the polishing pad by blowing a gas on the polishing pad during polishing. The polishing apparatus includes a pad temperature control mechanism having at least one gas ejection nozzle for ejecting a gas toward the polishing pad and configured to blow the gas onto the polishing pad to control a temperature of the polishing pad, and an atomizer having at least one nozzle for ejecting a liquid or a mixed fluid of a gas and a liquid and configured to blow the liquid or the mixed fluid onto the polishing pad to remove foreign matters on the polishing pad. The pad temperature control mechanism and the atomizer are formed into an integral unit.

    摘要: The present invention provides methods for cleaning the surface of CMP polishing pads comprising blowing a stream or curtain of forced air or gas from a source onto the surface of a CMP polishing pad substrate at a pressure of from 170 kPa (24.66 psig) to 600 kPa (87 psig), towards a vacuum source, the forced air or gas blowing at an angle of from 6 to 15° from a vertical plane which lies normal to the surface of the substrate, traverses the entire width of the surface of the substrate, and passes through the source of the forced air or gas, while, at the same time conveying along a horizontal plane the CMP polishing pad so that the entire surface of the CMP polishing pad surface is exposed to the forced air or gas at least one time; and, vacuuming the surface of the CMP polishing pad at a point on the surface which is downstream from a point at which the stream curtain of forced air or gas contacts the surface of the CMP polishing pad.
