Abstract:
An aluminum gas distribution plate refurbishment system combines a multi-beam inductively coupled plasma (AP-ICP) torch and vacuum discharge chuck. Plasma beams are employed to clean and restore to service the many gas flow passages in aluminum type gas distribution plates. Several parallel supersonic plasma beams of uniform density are produced from a single upper and lower AP-ICP plasma reactor arranged in totem pole that are driven by two pairs of opposing spiral planar RF induction RF antennas. These plasma beams are focused inside the gas flow passages to etch, heat, and deposit nanoparticles within. The vacuum discharge chuck includes a capacitively coupled plasma (CCP) reactor to generate a positive species discharge immediately beneath the gas distribution plates. This overcomes and undoes a Debye Sheathing effect, a electron-fed negative space charge blocking occurring above, and unknots any congested plasma beams in the gas flow passages.

Claim (Index 5):
The plasma device of  claim 4 , wherein the plasma reactor further comprises:\n a sheathing gas input; a selectable discharge gas input that selects amongst argon, hydrogen, and hydrogen chloride to variously support an etch, clean, heat, deposit, and anneal sequence.
