Abstract:
1. A dual zone plasma processing chamber, comprising: a first substrate support having a first support surface adapted to support a first substrate within the processing chamber; a second substrate support having a second support surface adapted to support a second substrate within the processing chamber; one or more gas sources in fluid communication with one or more gas distribution members supplying process gas to a first zone adjacent to the first substrate support and a second zone adjacent to the second substrate support; and a radio-frequency (RF) antenna adapted to inductively couple RF energy into the interior of the processing chamber and energize the process gas into a plasma state in the first and second zones, wherein the antenna is located between the first substrate support and the second substrate support wherein the first support surface is parallel to the second support surface and the antenna is a planar antenna oriented parallel to the first and second support surfaces.
