Abstract:
A versatile high throughput deposition apparatus includes a process chamber and a workpiece platform in the process chamber. The workpiece platform can hold a plurality of workpieces around a center region and to rotate the plurality of workpieces around the center region. Each of the plurality of workpieces includes a deposition surface facing the center region. A gas distribution system can distribute a vapor gas in the center region of the process chamber to deposit a material on the deposition surfaces on the plurality of workpieces. A magnetron apparatus can form a closed-loop magnetic field near the plurality of workpieces. The plurality of workpieces can be electrically biased to produce a plasma near the deposition surfaces on the plurality of workpieces.
