Perkin-Elmer's­ Model 4410 delta cathode production sputtering system is designed for high yield in production environments­ demanding maximum throughput for metal deposition. It also provide a high level of flexibility in process control for other materials.

The 4410 uses a delta-shaped­ cathode that eliminate the need for a large-area uniformity-shapi­ng aperture. This dramatically­ increases throughput while maintaining high wafer-to-wafer­ uniformity.

Contrasted with circular cathodes, target utilization is substantially­ higher. Up to 35% of the target can be sputtered before target change, and some 60% of the sputtered material actually reaches the substrate pallet. This results in a lower cost per wafer and less frequent target changes. Up to three delta or 8-inch round targets may be installed for sequential deposition of three different materials without breaking vacuum.

The 4410 employs a fast cycle load lock, two-stage cryopump and full flood Meissner trap to maintain the process chamber at high vacuum and in a clean condition at all times. The process chamber is fabricated of stainless steel for contamination-fr­ee performance.­ A base pressure better than 5 X 10-7 Torr is achieved within 3.5 minutes from loading substrates into the load lock. Typical cycle time, with optional load lock heating and pumping, is 12 to 15 minutes for the deposition of 1 micron of aluminum.
