Classification: CPC H | IPC H

Claim 0:
1. A plasma processing device comprising:
a dielectric window comprising a plasma exposed surface and an air exposed surface;
a vacuum chamber coupled with the dielectric window, wherein the vacuum chamber and the plasma exposed surface of the dielectric window cooperate to enclose a plasma processing gas, wherein the dielectric window seals an opening of the vacuum chamber;
an energy source positioned adjacent to the dielectric window, wherein the energy source transmits electromagnetic energy through the dielectric window and into the vacuum chamber such that the electromagnetic energy forms an elevated temperature region in the dielectric window and transforms at least a portion of the plasma processing gas into a plasma;
at least one air amplifier in fluid communication with the air exposed surface of the dielectric window; and
a plenum in fluid communication with the air exposed surface of the dielectric window and the at least one air amplifier to receive cooling air from the at least one air amplifier, wherein the plenum is formed as multiple segments united with one another, wherein each segment comprises at least one inlet and at least one outlet that outputs air directly into a pressure region partially surrounded by the plenum, wherein the at least one air amplifier is external to the plenum.
