    摘要: An apparatus, as well as a method, determines an endpoint of chemical mechanical polishing a metal layer on a substrate. The method of the apparatus includes bringing a surface of a substrate into contact with a polishing pad that has a window; causing relative motion between the substrate and the polishing pad; directing a light beam through the window, the motion of the polishing pad relative to the substrate causing the light beam to move in a path across the substrate; detecting light beam reflections from the substrate and a retaining ring; generating reflection data associated with the light beam reflections; dividing the reflection data into a plurality of radial ranges; and identifying the predetermined pattern from the reflection data in the plurality of radial ranges to establish the endpoint.

    摘要: A process for removing unwanted deposition build-up from one or more interior surfaces of a substrate processing chamber after depositing a layer of material over a substrate disposed in the chamber. In one embodiment the process comprises transferring the substrate out of the chamber; flowing a first gas into the substrate processing chamber and forming a plasma within the chamber from the first gas in order to heat the chamber; and thereafter, extinguishing the plasma, flowing an etchant gas into a remote plasma source, forming reactive species from the etchant gas and transporting the reactive species into the substrate processing chamber to etch the unwanted deposition build-up.

    摘要: A compressible film that is detachably securable to a surface of a rigid structure in the carrier head. The compressible film has a plurality of apertures positioned to create a non-uniform pressure distribution on a substrate during polishing so as to improve polishing uniformity. The apertures may be spaced and positioned to provide a pressure distribution on the substrate that is locally uniform but globally non-uniform.

    摘要: A carrier head with a flexible member connected to a base to define a first chamber, a second chamber and a third chamber. A lower surface of the flexible member provides a substrate receiving surface with an inner portion associated with the first chamber, a substantially annular middle portion surrounding the inner portion and associated with the second chamber, and a substantially annular outer portion surrounding the middle portion and associated with the third chamber. The width of the cuter portion may be significantly less than the width of the middle portion. The carrier head may also includea flange connected to a drive shaft and a gimbal pivotally connecting the flange to the base.

    摘要: A gas distribution showerhead is designed to allow deposition of uniformly thick films over a wide range of showerhead-to-wafer spacings. In accordance with one embodiment of the present invention, the number, width, and/or depth of orifices inlet to the faceplate are reduced in order to increase flow resistance and thereby elevate pressure upstream of the faceplate. This elevated upstream gas flow pressure in turn reduces variation in the velocity of gas flowed through center portions of the showerhead relative to edge portions, thereby ensuring uniformity in thickness of film deposited on the edge or center portions of the wafer.
