Patent ID: 8297225

Claim:
A capacitively coupled switchable reactor operable in plasma chemical vapor deposition (CVD) mode and etch mode to process a substrate, comprising: a chamber body; an anode situated at the ceiling of the chamber body, the anode being coupled to ground; a gas injection apparatus coupled to a deposition gas source for selectively injecting deposition gas, etching gas, or a mixture of deposition gas and etching gas into the chamber; a susceptor situated within the chamber body; a heater situated within the susceptor; an electrode situated within the susceptor; a high frequency RF generator coupled to the electrode; a low frequency RF generator coupled to the electrode; and, a controller operable to switch the operational parameters of the gas injection apparatus, the high frequency RF generator and the low frequency RF generator so as to selectively operate the chamber in one of CVD mode, etch mode, and a combined CVD and etch mode.
