Abstract:
1. An end effector for transferring a substrate in a processing system, the end effector comprising: a first base member; a second base member rotationally coupled to the first base member by an effector arm; at least one arm member rotationally coupled to the second base member by at least one lateral effector arm, wherein: at least one blade assembly rotationally coupled to the at least one arm member, the blade assembly comprising at least two substrate supporting surfaces disposed on opposite sides of the blade assembly and positioned to retain at least two substrates simultaneously on the blade assembly, wherein the at least two substrate supporting surfaces each include a sensor for detecting a position of its at least two substrates relative to the respective substrate supporting surface and wherein the at least one blade assembly comprises a first blade assembly rotationally coupled to the first arm member and a second blade assembly rotationally coupled to the second arm member.
