Abstract:
A device and method of spreading plasma which allows for plasma etching over a larger range of process chamber pressures. A plasma source, such as a linear inductive plasma source, may be choked to alter back pressure within the plasma source. The plasma may then be spread around a deflecting disc which spreads the plasma under a dome which then allows for very even plasma etch rates across the surface of a substrate. The apparatus may include a linear inductive plasma source above a plasma spreading portion which spreads plasma across a horizontally configured wafer or other substrate. The substrate support may include heating elements adapted to enhance the etching.

Claim (Index 11):
The plasma etching process chamber of  claim 10  wherein said spreading disc comprises a curved surface facing said constrictor plate.
