Abstract:
A method for processing a microelectronic workpiece in a processing apparatus having a set of processing stations in a row, the method comprising:holding a first microelectronic workpiece with a first end-effector connected directly to a pivot point along a fixed-length section of an arm that projects directly from a member which moves along and rotates about a lift path; holding a second microelectronic workpiece with a second end-effector connected directly to the pivot point along the fixed-length section of the arm; positioning the first microelectronic workpiece in a first plane a first distance from the arm and positioning the second microelectronic workpiece in a second plane a second distance from the arm, the second distance being different than the first distance; and rotating the first end-effector and/or the second end-effector to position the first and second microelectronic workpieces over the arm such that at least a portion of the first microelectronic workpiece is under at least a portion of the second microelectronic workpiece.
