PLASMA REACTOR WITH CHAMBER WALL TEMPERATURE CONTROL

摘要

Apparatus for processing substrates are provided herein. In some embodiments, an apparatus includes a first conductive body disposed about a substrate support in the inner volume of a process chamber; a first conductive ring having an inner edge coupled to a first end of the second conductive body and having an outer edge disposed radially outward of the inner edge; a second conductive body coupled to the outer edge of the first conductive ring and having at least a portion disposed above the first conductive ring, wherein the first conductive ring and the at least a portion of the second conductive body partially define a first region above the first conductive ring; and a heater configured to heat the first conductive body, the second conductive body, and the first conductive ring.
