Abstract: A robotic single axis system includes an effector moveable around a single rotating axis. The system is substantially concentrically arranged and mounted adjacent a wafer chuck of a precision stage. The robotic effector has a tangential distal end with a carrying face for positioning the wafer between concentric pinlifters raising from the wafer chuck. The pinlifters load and unload the wafer from the effector. The effector reaches with addition of the stage's travel into a cassette and alternating into a prealigner positioned on top of each other on an adjacent elevator. The elevator provides Z-axis movement so that the effector may load and unload wafers from the cassette, and alternating inserts a carried wafer into the prealigner.

Abstract: A compact pinlifter assembly is fitted in a substantially enclosed cavity within a wafer chuck such that an overall outside shape of the wafer chuck remains highly unaffected. The pinlifter assembly includes wedge guides providing a movement path in a wedge angle relative to the wafer holding face. A pin actuator is driven along the wedge guides transforming its movement along the wedge guides into a vertical movement of the lifting pins perpendicularly sliding between the cavity and the wafer holding face. The combination of wedge guides and pin actuator takes advantage of the relatively large lateral dimensions of the wafer chuck to move the pin actuator between end positions that are in a distance multiple of the pin lifters movement. Due to the wedge angle, the actuators comparatively large scale movement is transformed in a highly precise, smooth and balanced movement of the pin lifters.

Abstract: A method and apparatus for DC-DC conversion. The apparatus includes a voltage detector (152) for detecting a voltage level in the circuit; a capacitive voltage doubler configuration of the DC to DC conversion circuits (130); a capacitive voltage tripler configuration of the DC to DC conversion circuits (130); selector circuitry (134) responsive to the voltage detector (152) for enabling the doubler or tripler configurations; and a voltage regulator (132) for regulating the converted DC voltages. The selector circuitry (134) initially enables the doubler, and then disables the doubler and enables the tripler when the voltage level drops below a reference voltage. In an alternate embodiment, high load signal HLVBB is provided when a high power load is to be enabled, such that the selector circuitry (134) temporarily disables the doubler and temporarily enables the tripler until the high load signal is inactive.

Abstract: A flipper for rotating and positioning a photomask in two flip orientations includes a flip unit rotatably held in a base. The flip unit includes a flip frame in which clamps are preferably spring loaded guided such that the clamps are oppositely and laterally displaceable between engaged positions and parking positions. A stepper motor rotates the flip unit between two flip orientations and positions the flip unit such that opposite inspection sides of the work piece are alternately oriented with respect to a single inspection direction. The flipper may be placed on or adjacent to a stage system of an inspection device. A robotically actuated effector may access the flipper for loading and unloading the work piece. In combination with an effector operating without lift motion, the clamps may feature wedge lift faces to lift the work piece off the effector during their actuation into engaged position.
