Ultra high speed uniform plasma processing system
First Claim
1. An apparatus for processing a substrate with a plasma, the apparatus comprising:
- a first electrode;
a second electrode;
a separating member directly contacting said first electrode and directly contacting said second electrode and forming a sidewall extending from said first electrode to said second electrode, said separating member composed of a dielectric material capable of electrically isolating said first electrode from said second electrode;
a processing region formed by said separating member, said first electrode, and said second electrode;
a process gas port for introducing a process gas to said processing region;
a vacuum port in said first electrode for evacuating said processing region to a sub-atmospheric pressure suitable for generating the plasma from the process gas in said processing region;
an electrically conductive shell surrounding said first electrode, said second electrode, and said separating member; and
an atmospheric pressure space between said shell and said first electrode, said second electrode, and said separating member.

Abstract
An apparatus for processing a substrate with a plasma. The apparatus includes first and second electrodes positioned with a spaced apart relationship. A separating ring has a vacuum-tight engagement with confronting surfaces of the first electrode and the second electrode to define an evacuatable processing region therebetween. Communicating with the processing region is a process gas port for introducing a process gas to the processing region. The processing region may be evacuated through a vacuum port defined in one of the first and second electrodes to a pressure suitable for exciting a plasma from the process gas in the processing region when the first and second electrodes are powered.
