More Information
Summary:An apparatus performs at least one of cleaning and drying a semiconductor wafer while rotating the semiconductor wafer. The apparatus has a rotating mechanism for rotating the semiconductor wafer, and a sensor for detecting a reference position such as a notch or an orientation flat of the semiconductor wafer. The semiconductor wafer may be stopped from rotating to align the reference position with a predetermined position based on an output signal from the sensor.
