概要（Overview）

The Perkin-Elmer 4400 Series is a fast cycle, water-cooled load locked system that uses circular or delta style cathodes. It has the advantage of eliminating the need to vent the process chamber for loading and unloading substrates, reducing pump down time, contamination, and target burn-in. This increases material utilization. The system is a general-purpose sputtering system with up to four 8 inch diameter circular cathodes that can use DC Magnetron, RF Magnetron, or RF Diode configurations. These can be sputtered sequentially without breaking vacuum. Power sources are available up to 2 kW RF and 5 kW DC.
