  • Patent number: 10453718
    Abstract: Embodiments disclosed herein generally relate to a slit valve door assembly for sealing an opening in a chamber. A slit valve door that is pressed against the chamber to seal the slit valve opening moves with the chamber as the slit valve opening shrinks so that an o-ring pressed between the slit valve door and the chamber may move with the slit valve door and the chamber. Thus, less rubbing of the o-ring against the chamber may occur. With less rubbing, fewer particles may be generated and the o-ring lifetime may be extended. With a longer lifetime for the o-ring, substrate throughput may be increased.

  • Patent number: 10262837
    Abstract: Embodiments of a gas diffuser plate for distributing gas in a processing chamber are provided. The gas distribution plate includes a diffuser plate having an upstream side and a downstream side, and a plurality of gas passages passing between the upstream and downstream sides of the diffuser plate. The gas passages include hollow cathode cavities at the downstream side to enhance plasma ionization. The depths, the diameters, the surface area and density of hollow cathode cavities of the gas passages that extend to the downstream end can be gradually increased from the center to the edge of the diffuser plate to improve the film thickness and property uniformity across the substrate. The increasing diameters, depths and surface areas from the center to the edge of the diffuser plate can be created by bending the diffuser plate toward downstream side, followed by machining out the convex downstream side. Bending the diffuser plate can be accomplished by a thermal process or a vacuum process.

  • Patent number: 9922854
    Abstract: The present invention generally relates to a vertical CVD system having a processing chamber that is capable of processing multiple substrates. The multiple substrates are disposed on opposite sides of the processing source within the processing chamber, yet the processing environments are not isolated from each other. The processing source is a horizontally centered vertical plasma generator that permits multiple substrates to be processed simultaneously on either side of the plasma generator, yet independent of each other. The system is arranged as a twin system whereby two identical processing lines, each with their own processing chamber, are arranged adjacent to each other. Multiple robots are used to load and unload the substrates from the processing system. Each robot can access both processing lines within the system.
