Abstract

Automated reactor system and process for etching or otherwise processing semiconductor wafers in a plasma environment. The wafers are carried into and out of a reaction chamber by a conveyor and processed on an individual basis. Within the chamber, an electrode mounted on a swinging arm carries each wafer from the conveyor to a processing position adjacent to a stationary electrode. Gas is admitted to the chamber, and the electrodes are energized to ionize the gas and form a plasma for processing the wafer between the electrodes.
