HOLLOW ANODE PLASMA REACTOR AND METHOD

摘要

The plasma processing apparatus includes a plasma chamber, a first electrode, a second electrode, and a plasma containment device. The plasma containment device has a plurality of slots and is electrically coupled to the first electrode. The containment device is configured to confine plasma within an inter-electrode volume while facilitating maximum process gas flow. When plasma is generated by applying electric fields to process gas within the inter-electrode volume, the containment device electrically confines the plasma to the inter-electrode volume without significantly restricting the flow of gas from the inter-electrode volume.
