  • Publication number: 20160087075
    Abstract: The present disclosure provides a transistor device and fabrication method thereof. A dummy gate is formed on a substrate. An interlayer dielectric layer is formed on the substrate and sidewall surfaces of the dummy gate. The interlayer dielectric layer has a top surface coplanar with a top surface of the dummy gate. A mask layer is formed on the top surface of the interlayer dielectric layer. The mask layer is used as an etch mask to remove the dummy gate to form a trench in the interlayer dielectric layer to provide a trench footing on sidewall surfaces of the trench and near a trench bottom. The trench footing is then removed by applying a dry etching process. A gate electrode is then formed in the trench to form a transistor with improved electrical performance.

  • Patent number: 9238724
    Abstract: A method of producing an elastomer composite. The method includes A) combining a first fluid comprising elastomer latex with a second fluid comprising particulate filler; B) causing the elastomer latex to coagulate, thereby forming masterbatch crumb; C) bringing the masterbatch crumb to a water content of about 1 weight percent to about 20 weight percent, thereby forming a de-watered coagulum; D) removing water from the de-watered coagulum by subjecting the dewatered coagulum to mechanical energy, thereby causing the dewatered coagulum to heat as a result of friction, while allowing the dewatered coagulum to achieve a temperature of about 130° C. to about 190° C., wherein water content is reduced to about 0.5% to about 3% and wherein substantially all of the decrease in water content is accomplished by evaporation, thereby producing a masticated masterbatch; and E) subjecting the masticated masterbatch to at least an additional 0.3 MJ/kg of mechanical energy while further reducing the water content.

  • Publication number: 20150341662
    Abstract: Prediction directions for cost calculation are reduced by preferentially selecting a direction in which a prediction pixel is generated by direct copy without filtering from among intra prediction directions to perform intra prediction. In addition to the roughly selected prediction direction, an amount of processing is reduced while deterioration of coding efficiency is prevented through comparison with preferentially selected prediction, such as DC prediction and planar prediction, and selection of second-stage prediction direction focused on a vicinity of roughly selected prediction direction.

  • Publication number: 20150280928
    Abstract: A novel method for performing replication of messages in a network that bridges one or more physical networks to an overlay logical network is provided. A physical gateway provides bridging between network nodes of a physical network and virtual machines in the overlay logical network by serving as an endpoint of the overlay logical network. The physical gateway does not replicate messages from the bridged physical network to destination endpoints in the overlay logical network directly, but instead tunnels the message-to-be-replicated to a designated tunnel endpoint in the overlay logical network. The designated tunnel endpoint in turn replicates the message that was tunneled to it to other endpoints in the overlay logical network.

  • Publication number: 20150103661
    Abstract: Some embodiments provide a novel method for distributing control-channel communication load between multiple controllers in a network control system. In some embodiments, the controllers manage physical forwarding elements that forward data between several computing devices (also called hosts or host computers), some or all of which execute one or more virtual machines (VMs). The method of some embodiments distributes a controller assignment list to the host computers. The host computers use this list to identify the controllers with which they need to interact to perform some of the forwarding operations of their associated logical forwarding elements. In some embodiments, agents executing on the host computers (1) review the controller assignment list to identify the appropriate controllers, and (2) establish control channel communications with these controllers to obtain the needed data for effectuating the forwarding operations of their associated physical forwarding elements.
