Atmospheric plasma processing systems and methods for manufacture of microelectronic workpieces

Systems and related methods are disclosed for atmospheric plasma processing of microelectronic workpieces, such as semiconductor wafers. For disclosed embodiments, a radio frequency (RF) generator generates an RF signal that is distributed to one or more plasma sources within a process chamber. The process chamber has an atmospheric pressure between 350 to 4000 Torr. The plasma sources are then scanned across a microelectronic workpiece to apply plasma gasses generated by the plasma generators to the microelectronic workpiece. The plasma sources can be individually scanned and/or combined in arrays for scanning across the microelectronic workpiece. Linear and/or angular movement can be applied to the plasma sources and/or the microelectronic workpiece to provide the scanning operation. Various implementations are disclosed.
