Patent ID: 7694688

Claim:
A cluster tool for cleaning a substrate, comprising: two or more process chambers that are configured to process a substrate in a vertical orientation, wherein the two or more process chambers are positioned a distance apart along a first direction; a robot assembly that comprises: a first robot having a robot blade assembly that has a substrate supporting surface, and the first robot is adapted to position a substrate at one or more points contained within a first plane, wherein the first plane is parallel to the first direction; an actuator that is coupled to the robot blade assembly and is adapted to position the substrate supporting surface in an angular orientation relative to a horizontal plane; a first motion assembly that is adapted to position the first robot in a third direction that is perpendicular to the first plane; and a second motion assembly that is adapted to position the first robot in a direction parallel to the first direction; a chamber actuator assembly that has two or more end-effector assemblies, wherein the chamber actuator assembly is adapted to position one of the two or more end-effector assemblies in each of the two or more process chambers simultaneously; two or more chamber pass-through supports that are each adapted to receive one or more substrates from the robot assembly; and a support actuator that is adapted to position the two or more chamber pass-through supports so that each of the two or more end-effector assemblies can receive a substrate from at least one of the two or more chamber pass-through supports.
