Transport Sequence



Pallet transport is completely automatic. Once the START button is depressed, the pallets are lowered on to the transport mechanism and moved through the process chambers. As soon as all pallets have cleared the load lock into the main chamber and the load lock valve closes, the end loading chamber can be opened and the next 28 pallets loaded into the system. Transport speed is preset. The transport drive is reversible. Pallets can be transported back and forth for sequential or multi-pass deposition.  Pallets transport can be stopped at any time. This permits the load lock valve to be closed when a pallet has cleared the load lock valve at the unload end chamber. The processed wafers can be then evaluated before the deposition process is allowed to continue on the remaining substrates.


Equipment Safety

The 9900 is completely interlocked for maximum personnel and equipment safety. All access panels, sputtering doors, chamber pressure switches, and water flow switches are interlocked to provide protection for personnel, the system and the wafer load in process.

Typical 9900 (5) Target  Sputtering System.
Load Lock

Up to 28 pallets can be loaded from either end of the system. Once the pallets are loaded into an end chamber and the load lock chamber has been evacuated to the preset pressure, the load lock valves open to the process chambers and the system is pumped down to a preset pressure before deposition.

CPA builds the most reliable systems in the industry! In actual on-line production use over the last seven years in some of the most active and successful fabrication facilities in the world, CPA's 9900 Series operated at better than 90% up-time, including normal shutdown for target replacement, chamber cleaning and pump service.
