摘要： Embodiments of the invention contemplate a shadow ring that provides increased or decreased and more uniform deposition on the edge of a wafer. By removing material from the top and/or bottom surfaces of the shadow ring, increased edge deposition and bevel coverage can be realized. In one embodiment, the material on the bottom surface is reduced by providing a recessed slot on the bottom surface. By increasing the amount of material of the shadow ring, the edge deposition and bevel coverage is reduced. Another approach to adjusting the deposition at the edge of the wafer includes increasing or decreasing the inner diameter of the shadow ring. The material forming the shadow ring may also be varied to change the amount of deposition at the edge of the wafer.

摘要： An apparatus for plasma processing a substrate is provided. The apparatus comprises a processing chamber, a substrate support disposed in the processing chamber, a shield member disposed in the processing chamber below the substrate support, and a lid assembly coupled to the processing chamber. The lid assembly comprises a conductive gas distributor coupled to a power source, and an electrode separated from the conductive gas distributor and the chamber body by electrical insulators. The electrode is also coupled to a source of electric power. The substrate support is formed with a stiffness that permits very little departure from parallelism. The shield member thermally shields a substrate transfer opening in the lower portion of the chamber body. A pumping plenum is located below the substrate support processing position, and is spaced apart therefrom.

摘要： A system and method for the detection of plasma excursions, such as arcs, micro-arcs, or other plasma instability, during plasma processing by directly monitoring RF current just prior to reaching an RF power electrode of a plasma processing chamber is provided. The monitored RF current may be converted to an RF voltage and then passed through a succession of analog filters and amplifiers to provide a plasma excursion signal. The plasma excursion signal is compared to a preset value, and at points where the plasma excursion signal exceeds the preset value, an alarm signal is generated. The alarm signal is then fed back into a system controller so that an operator can be alerted and/or the processing system can be shut down. In one embodiment, the RF current amplified and converted to a digital signal for digital filtering and processing. In certain embodiments, multiple processing regions can be monitored by a single detection control unit.
