  • Patent number: 8288283
    Abstract: A process of forming an integrated circuit using a palladium CMP operation in which 25 to 125 ppm aluminum is added to the CMP slurry, allowing a palladium removal rate of at least 80 nanometers per minute at a polish pad pressure less than 9 psi and a surface speed between 1.9 and 2.2 meters per second. The palladium CMP operation may be applied to form a palladium bond pad cap after which an external bond element is formed on the palladium bond pad cap. Alternatively, the palladium CMP operation may be applied to form a palladium interconnect conductor in a first dielectric layer.
    Type: Grant

  • Publication number: 20080242089
    Abstract: A method of manufacturing a semiconductor device. A first thickness of a copper layer located over a semiconductor substrate is removed by chemical-mechanical polishing (CMP) on a first platen using a first polishing slurry. The copper layer is located over a barrier layer. A remaining thickness of the copper layer is removed on a second platen using a second polishing slurry. A portion of the barrier layer on the second platen is removed using a third polishing slurry. The third polishing slurry has a substantially different composition from the second polishing slurry.

  • Patent number: 6896588
    Abstract: Light is incident on a semiconductor wafer polish surface and an adjacent reference surface (80). The reflected light from each surface is detected by a detector (35) positioned beneath the surfaces. The signals derived from each source of reflected light is analyzed in a electronic system (37) and an endpoint for a chemical mechanical polish process is determined as a function of both signals.

  • Publication number: 20030045208
    Abstract: A chemical mechanical polishing includes a first spindle operable to rotate with respect to a central axis of the first spindle. A first polishing pad is coupled with the first spindle, and the first polishing pad has a first surface extending along a plane generally perpendicular to the central axis of the first spindle. A wafer carrier is included that is adapted to receive a wafer with a second surface generally parallel to the first surface of the first polishing pad. The wafer carrier is operable to rotate with respect to a central axis of the wafer carrier. The first surface of the first polishing pad is moveable along the central axis of the first spindle from a first position, wherein the first surface is spaced from the second surface, and a second position, wherein the first surface generally contacts the second surface.
