ABSTRACT:
A cleaning system for n semiconductor manufacturing equipment includes a working area and a service area. A wafer process area in the service area performs a semiconductor manufacturing process. A wafer transfer area is spatially connected to the wafer process area, and transfers a wafer from the working area to the wafer process area. An air supply device supplies clean air to the wafer transfer area and the wafer process area. A particle measurer continuously checks for any malfunction or defect of the air supply device, and measures in real time an impurity particle count of the air in the wafer transfer area so as to detect any abnormally high pollution level in the wafer transfer area.
