  • Publication number: 20180358220
    Abstract: Methods and apparatuses for etching metal-doped carbon-containing materials are provided herein. Etching methods include using a mixture of an etching gas suitable for etching the carbon component of the metal-doped carbon-containing material and an additive gas suitable for etching the metal component of the metal-doped carbon-containing material and igniting a plasma to selectively remove metal-doped carbon-containing materials relative to underlayers such as silicon oxide, silicon nitride, and silicon, at high temperatures. Apparatuses suitable for etching metal-doped carbon-containing materials are equipped with a high temperature movable pedestal, a plasma source, and a showerhead between a plasma generating region and the substrate.

    Abstract: Various embodiments of systems and methods for integrated services for form generation and maintenance on cloud are described herein. The method includes receiving a request for a form-related service from a client. The form-related service may comprise at least one of generating a form, printing the form, extracting one or more form templates, extracting one or more form schemas, and uploading one or more tenant-created form templates onto a cloud template store. The received request is authenticated. Upon a successful authentication, one or more actions may be performed to render an output based upon the request. The output may include one of a form, the one or more form templates, the one or more form schemas, and a notification for successful or unsuccessful uploading of the one or more tenant-created form templates onto the cloud template store. Upon unsuccessful authentication, an error message may be displayed.

  • Publication number: 20170305232
    Abstract: Disclosed is a method to form arbitrarily shaped, uniform, lightweight, thermally insulating and acoustically absorptive automotive components with controllable density, thickness, porosity, and surface integrity. The method is based on natural cellulosic fibers such as those found in cardboard and paper and uses a thermoplastic fiber and particle slurry to form fusible components. The method produces components having the benefit of commercially available thermoformed fiber mats or open-cell extruded foam components with excellent acoustical properties, enhanced thermal insulation, and are light weight, which limits engine inefficiency, and the high cost of such products so as to allow large scale implementation.

  • Patent number: 9780797
    Abstract: The present invention relates generally to integrated circuits. More particularly, the present invention provides a circuit and method for regulating a voltage for a high speed serializer/deserializer (SerDes) device. But it will be recognized that the technique can be used for regulating memory devices (e.g., DDR 4 SDRAM devices, DDR4 register devices, DDR4 controller devices), and other high speed data applications. In various embodiments, phase-interpolator is implemented in conjunction with a delay-lock loop (DLL) and an SR latch, where one or more outputs of the DLL is used by the SR latch. Additionally, such techniques can be used for a variety of applications such as network and/or computer storage systems, computer servers, hand held computing devices, portable computing devices, computer systems, network appliances and/or switches, routers, and gateways, and the like.

  • Publication number: 20170257237
    Abstract: The present invention is directed to communication systems. More specifically, embodiments of the present invention provide a technique and system thereof for performing eye modulation. Eye modulation is performed at the transmission side of a PAM communication system to compensate for distortion and non-linearity and generate an output waveform. Spacing among eye levels is adjusted by performing symmetric modulation using ? parameter and asymmetric modulation using ? parameter. A correction module measures the output waveform and sends feedback signals to a control module to adjust the ? parameter and the ? parameter. There are other embodiments as well.

  • Patent number: 9203605
    Abstract: A phase interpolator (PI) is provided to adjust the phase of a clock such that the phase is aligned to an incoming data pattern from a data stream. The data can be captured from a device such as a flip-flop or the like. The present technique uses a PI (digital to phase) and a digital state machine in a feedback loop to set the correct digital code to the PI inputs to achieve an appropriate clock phase. Of course, there can be variations.
