  • Patent number: 9758869
    Abstract: Embodiments disclosed herein generally relate to an apparatus having an anodized gas distribution showerhead. In large area, parallel plate RF processing chambers, mastering the RF return path can be challenging. Arcing is a frequent problem encountered in RF processing chambers. To reduce arcing in RF processing chambers, straps may be coupled to the susceptor to shorten the RF return path, a ceramic or insulating or anodized shadow frame may be coupled to the susceptor during processing, and an anodized coating may be deposited onto the edge of the showerhead that is nearest the chamber walls. The anodized coating may reduce arcing between the showerhead and the chamber walls and therefore enhance film properties and increase deposition rate.

  • Patent number: 9677177
    Abstract: The present invention generally relates to a substrate support for use in a processing chamber. The substrate support is divided into quadrants with each quadrant capable of heating independent of the other quadrants. The independent heating permits the substrate support to provide different heating to either different substrate simultaneously disposed on the substrate support or to different areas of a common substrate. Thus, the substrate heating may be tailored to ensure desired processing of the substrate or substrates occurs.

  • Publication number: 20160240312
    Abstract: The present disclosure generally relates to capacitors having a multilayer dielectric material between two electrodes. The multilayer dielectric material can have a small thickness with little to no breakdown strength reduction. By utilizing a multilayer dielectric structure in a capacitor, not only can the breakdown strength remain at an acceptable level, but the collective thickness of the capacitor may be reduced to accommodate the higher density pixels for display devices or any device that utilizes a capacitor.

  • Publication number: 20160208380
    Abstract: An apparatus for introducing gas into a processing chamber comprising one or more gas distribution tubes having gas-injection holes which may be larger in size, greater in number, and/or spaced closer together at sections of the gas introduction tubes where greater gas conductance through the gas-injection holes is desired. An outside tube having larger gas-injection holes may surround each gas distribution tube. The gas distribution tubes may be fluidically connected to a vacuum foreline to facilitate removal of gas from the gas distribution tube at the end of a process cycle.

  • Patent number: 9287137
    Abstract: Embodiments of the disclosure generally provide methods of forming a silicon containing layers in TFT devices. The silicon can be used to form the active channel in a LTPS TFT or be utilized as an element in a gate dielectric layer, a passivation layer or even an etch stop layer. The silicon containing layer is deposited by a vapor deposition process whereby an inert gas, such as argon, is introduced along with the silicon precursor. The inert gas functions to drive out weak, dangling silicon-hydrogen bonds or silicon-silicon bonds so that strong silicon-silicon or silicon-oxygen bonds remain to form a substantially hydrogen free silicon containing layer.

  • Publication number: 20160056019
    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: 9269923
    Abstract: A method and apparatus for depositing an inorganic layer onto a substrate is described. The inorganic layer may be part of an encapsulating film utilized in various display applications. The encapsulating film includes one or more inorganic layers as barrier layers to improve water-barrier performance. An oxygen containing gas, such as nitrous oxide, is introduced during the deposition of the inorganic layer. As a result, the inorganic layer is lower in stress and may obtain a water vapor transmission rate (WVTR) of less than 100 mg/m2-day.
