ABSTRACT:
A substrate processing system has a first substrate cleaner and a second substrate cleaner. The first substrate cleaner comprises a forward portion and a rear portion. The forward portion includes a rotatable substrate support. The rear portion is vertically thicker than the forward portion. The rear portion includes a device for rotating the support. The second substrate cleaner includes the elements included in the first substrate cleaner. The second substrate cleaner is stacked above the first substrate cleaner with the forward portions being vertically aligned and the rear portions being vertically aligned. A space is formed between the forward portions to permit access to the forward portion of the first substrate cleaner and to permit ample gas flow into the area between the forward portions of the first and the second substrate cleaners.
