Patent ID: 7074246

Claim:
A semiconductor workpiece processing tool, comprising: an input/output station configured to carry a plurality of semiconductor workpieces; a workpiece conveyor having a workpiece transport unit, the workpiece transport unit having a carriage and an arm pivotably coupled to the carriage, the arm having a support member configured to carry a workpiece; a plurality of workpiece processing stations positioned adjacent to the workpiece conveyor, the workpiece processing stations being configured to process only one workpiece at a time, at least one of the workpiece processing stations including: a processing chamber coupled to a supply of processing fluid; and a workpiece support cantilevered over the processing chamber, the workpiece support being movable relative to the processing chamber between a first position for receiving a single workpiece and a second position for processing the single workpiece, the workpiece support having a moveable workpiece holder, the workpiece holder having multiple support elements positioned to contact a single workpiece and carry the single workpiece face-down for processing when the workpiece support is in the second position; and a controller operatively coupled to the workpiece conveyor, the controller being programmed with instructions directing the workpiece transport unit to move along the conveyor and access (a) the input/output station, and (b) one or more of the plurality of processing stations with the arm-mounted support member.
