ABSTRACT:
This disclosure provides an approach for cleaning an ion implanter. In this disclosure, there is a vacuum device having an in-take port adapted to receive a contaminant removing hose. The vacuum device and hose are configured to provide constant suction to the ion implanter. A dry ice blaster having a dry ice dispensing hose is configured to supply dry ice. A sealing plate is adapted to attach to an access section of a processing region of the ion implanter. The sealing plate has a first opening configured to receive the contaminant removing hose and the dry ice dispensing hose.
