    摘要: The present invention generally relates to a substrate transferring system having an alignment mechanism of a surface and to two points. One embodiment of the present invention provides a load cup for transferring a substrate. The load cup comprises a cup having a substrate supporting surface configured to support the substrate thereon, and two alignment pins protruding from the cup outside the substrate supporting surface, wherein the two alignment pins are both positioned at a first distance away from a center of the substrate supporting surface, and the cup is pivotable about a pivoting point positioned at a second distance away from the center.

    摘要: A system for chemical mechanical polishing having a carrier head with pressurizeable chambers that can be configured into pressure zones is described. The system includes a carrier head with a membrane for contacting a substrate during polishing. Pressurizeable chambers behind the membrane are in communication with pressure inputs. The pressure inputs can each supply a different pressure to the pressurizeable chambers. Some of the pressurizeable chambers can be in communication with more than one pressure input. Zones of pressure can be arranged, where each zone includes one or more pressurizeable chambers. The zones can be configurable by altering the pressurizeable chambers that make up each zone.
