Abstract:
1. A system for processing semiconductor substrates comprising: a chamber comprising at least one substrate transfer passage formed in the chamber and a slit valve adapted to selectively seal the transfer passage; a robot adapted for substrate transfer, the robot being disposed within the chamber and having an end effector; a gripper assembly coupled to the robot and configured to retain a circular semiconductor substrate on the end effector, the gripper assembly being mechanically actuatable by a structure remote from the robot and end effector during substrate transfer; wherein the gripper assembly comprises: wherein the system further comprises: a striker plate positioned adjacent the transfer passage to engage the gripper assembly as the end effector is moved through the passage, the striker plate being positionable along a direction defined by an axis of extension of the end effector through the passage; and a mounting block coupled to at least one of the chamber and slit valve, the block having a threaded hole for receiving a stud extending from the striker plate.
