  • Centrifugal wafer processor
    Patent number: 4571850
    Abstract: In a rinser/dryer for carriers of semiconductor wafers, a rotatable frame containing the carrier is directly mounted to, and cantilevered from the drive motor. A container encloses the rotatable frame and carrier. A gas pressurized labyrinth seal separates the inside of the container from the drive motor to prevent contamination. A raised portion in the labyrinth seal, with gas inlets on each side of the raised portion, forms a pressure barrier inhibiting the passage of moisture and contaminates across the barrier.
