    Abstract: A process system for processing a semiconductor wafer or other similar flat workpiece has a head including a workpiece holder. A motor in the head spins the workpiece. A head lifter lowers the head to move the workpiece into a bath of liquid in a bowl. Sonic energy is introduced into the liquid and travels through the liquid to the workpiece, to assist in processing. The head is lifted to bring the workpiece to a rinse position. The bath liquid is drained. The workpiece is rinsed via radial spray nozzles in the base. The head is lifted to a dry position. A reciprocating swing arm sprays a drying fluid onto the bottom surface of the spinning wafer, to dry the wafer.
