Abstract

A substrate processing apparatus including a frame, a first SCARA arm connected to the frame, including an end effector, configured to extend and retract along a first radial axis; a second SCARA arm connected to the frame, including an end effector, configured to extend and retract along a second radial axis, the SCARA arms having a common shoulder axis of rotation; and a drive section coupled to the SCARA arms is configured to independently extend each SCARA arm along a respective radial axis and rotate each SCARA arm 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 on a common transfer plane.
