摘要:
Inspection equipment for detecting defects in a wafer is provided in a coating and developing system including a plurality of kinds of processing units for performing processing necessary for coating a wafer with a resist and processing necessary for developing the resist on the wafer. The transfer of the wafer between the processing units and the inspection equipment is performed by means of a main transfer device. The inspection equipment sends an inspection result as a detection signal to a controller, and the controller which receives the detection signal controls exposure conditions for an aligner according to the presence or absence of defects and adjusts a frequency regulating mechanism to control inspection frequency. The wafer is transferred between the processing units and the inspection equipment by the main transfer device, whereby the wafer is not artificially contaminated.
