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 19):
The method of  claim 18  wherein the ratio of the diameter of the annulus in the constrictor plate to the interior diameter of the cylindrical plasma chamber is in the range of 1:8 to 1:3.
