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.

摘要： An edge ring assembly surrounds a substrate support surface in a plasma etching chamber. The edge ring assembly comprises an edge ring and a dielectric spacer ring. The dielectric spacer ring, which surrounds the substrate support surface and which is surrounded by the edge ring in the radial direction, is configured to insulate the edge ring from the baseplate. Incorporation of the edge ring assembly around the substrate support surface can decrease the buildup of polymer at the underside and along the edge of a substrate and increase plasma etching uniformity of the substrate.

摘要： A yttria insulator ring for use in a plasma processing apparatus is provided to minimize arcing between the apparatus and a ground extension, while also increasing a mean time between cleanings (MTBC). The yttria insulator ring may be located between a ground extension and a plasma generation zone, or gap, of the chamber of the apparatus, as well as between an edge ring and the ground extension. Compared to a quartz ring, the yttria insulator ring can also provide improved semiconductor substrate uniformity because of improved RF coupling as a result of decreased reactivity and increased dielectric constant.

摘要： The present invention provides a plasma processing apparatus, system, and method for providing RF power to a plasma processing chamber. The plasma processing system includes an RF generator, a plasma chamber, a match network box, a first cable, a second cable, and means for electrically isolating the match network box. The RF generator is generates RF power for transmission to the plasma chamber. The plasma chamber receives the RF power for processing the wafer and is characterized by an internal impedance during the plasma processing. The plasma chamber has one or more walls for returning RF currents. The match network box is capable of receiving the RF currents and generates an impedance that matches the internal impedance of the plasma chamber to the impedance of the RF generator. The first cable is coupled between the RF generator and the match network box for transmitting RF power between the RF generator and the match network box. The second cable is coupled between the match network box and the plasma chamber for transmitting RF power between the match network and the plasma chamber. The second cable provides a return path for an RF return current from the plasma chamber to the match network box. The electrically isolating means electrically isolates the match network box from electrical contacts with the plasma chamber such that only the second cable provides the return path for the RF return current from the plasma chamber to the match network box.
