Abstract:
1. A substrate processing apparatus comprising: a frame; a first SCARA arm connected to the frame, the first SCARA arm includes an end effector and is configured to extend and retract along a first radial axis; a second SCARA arm connected to the frame, the second SCARA arm includes an end effector and is configured to extend and retract along a second radial axis, the first and second SCARA arms having a common shoulder axis of rotation; and a drive section coupled to the first and second arms, the drive section being configured to independently extend each of the first and second SCARA arms along a respective radial axis and rotate each of the first and second SCARA arms about the common shoulder axis of rotation where the first radial axis is angled relative to the second radial axis and the end effector of a respective arm is aligned with a respective radial axis; wherein each end effector is configured to hold at least one substrate and the end effectors are located coincident on a common transfer plane.
