Abstract:
1. A wafer cassette support device for use in aligning a wafer cassette in semiconductor manufacturing equipment, the device comprising: a wafer cassette support including a base plate; a control section including a position sensor situated relative to the base plate so as to sense whether a wafer cassette is at a stably supported position on the base plate, and a controller operatively connected to the position sensor so as to generate and output a motor drive signal when the position sensor senses the presence of a wafer cassette at a stably supported position on the base plate; and a cassette moving section including a motor operatively connected to said controller so as to receive the motor drive signal therefrom and output a driving force when said signal is received, and a movable first wafer cassette guide connected to said motor so as to be driven by the driving force output by the motor.
