System and method of wafer processing and ion implantation |
摘要 |
The invention provides for a wafer system and related method in which two load lock chambers having load lock pedestals are provided adjacent to a vacuum process chamber through a vacuum intermediate chamber, a passage opening is provided between the vacuum process chamber and the vacuum intermediate chamber and two wafer retaining arms are installed between a platen device in the vacuum process chamber and the vacuum intermediate chamber, the two wafer retaining arms being reciprocably movable between the corresponding load lock pedestals and the platen device while passing through the passage opening and crossing with an overpass each other at different levels. By retaining an unprocessed wafer by one of the wafer retaining arms and retaining a processed wafer by the other wafer retaining arm, transfer of the unprocessed wafer from one of the load lock pedestals to the platen device and transfer of the processed wafer from the platen device to the other load lock pedestal are performed simultaneously.
