Abstract:
A vacuum processing system, comprising:a first chamber; at least one second chamber cooperatively engaged with the first chamber; a wafer handler disposed within the first chamber; and an end effector having: a fixed end attached to the wafer handler and a free end; a first wafer support proximate to the fixed end and having opposing edges; two wafer end supports spaced apart and proximate to the free end, the wafer end supports having opposing edges wider than the opposing edges of the first wafer support, the first wafer support and the two wafer end supports having at least one end shoe adapted to capture the wafer laterally between the two wafer end supports and the first wafer support and each wafer end support adapted to support a bottom side of a wafer; a wafer sense cutout; an end recess between the two wafer end supports; and a first side recess and a second side recess disposed between at least the first wafer support and the two wafer end supports on opposing sides of the end effector.
