  • Patent number: 9443951
    Abstract: Fin-defining mask structures are formed over a semiconductor material layer having a first semiconductor material and a disposable gate structure is formed thereupon. A gate spacer is formed around the disposable gate structure and physically exposed portions of the fin-defining mask structures are subsequently removed. The semiconductor material layer is recessed employing the disposable gate structure and the gate spacer as an etch mask to form recessed semiconductor material portions. Embedded planar source/drain stressors are formed on the recessed semiconductor material portions by selective deposition of a second semiconductor material having a different lattice constant than the first semiconductor material. After formation of a planarization dielectric layer, the disposable gate structure is removed. A plurality of semiconductor fins are formed employing the fin-defining mask structures as an etch mask. A replacement gate structure is formed on the plurality of semiconductor fins.

    Abstract: A chemical vapor deposition reactor and a method of wafer processing are provided. The reactor can include a reaction chamber having an interior and an entry port for insertion and removal of substrates, a gas inlet manifold communicating with the interior of the chamber for admitting process gasses to form a deposit on substrates held within the interior, a shutter mounted to the chamber, and one or more cleaning elements mounted within the chamber. The shutter can be movable between (i) a run position in which the cleaning elements are remote from the exhaust channel and (ii) a cleaning position in which the one or more cleaning elements engage with the shutter so that the cleaning elements remove deposited particles from the shutter upon movement of the shutter to the cleaning position.

  • Patent number: 9287399
    Abstract: A faceted intrinsic buffer semiconductor material is deposited on sidewalls of a source trench and a drain trench by selective epitaxy. A facet adjoins each edge at which an outer sidewall of a gate spacer adjoins a sidewall of the source trench or the drain trench. A doped semiconductor material is subsequently deposited to fill the source trench and the drain trench. The doped semiconductor material can be deposited such that the facets of the intrinsic buffer semiconductor material are extended and inner sidewalls of the deposited doped semiconductor material merges in each of the source trench and the drain trench. The doped semiconductor material can subsequently grow upward. Faceted intrinsic buffer semiconductor material portions allow greater outdiffusion of dopants near faceted corners while suppressing diffusion of dopants in regions of uniform width, thereby suppressing short channel effects.

  • Patent number: 9257858
    Abstract: A charging circuit and method for charging a power storage device in a power over Ethernet environment are necessary to prevent unnecessary power consumption. Power sourcing equipment continuously supplies power to a connected device after determining that the device is compatible. In order to prevent supply of power after a power storage device attains full charge, a charging circuit may include an interface for supplying electric power; a sensing circuit including a switch in series with a resistor; and a voltage detection circuit. The voltage detection circuit may communicate with the sensing circuit and may output a first signal that turns the switch OFF when the voltage of the power storage device is greater than or equal to a first voltage and may output a second signal that turns the switch ON when the voltage of the power storage device is less than or equal to a second voltage.

  • Publication number: 20150334391
    Abstract: A method for decoding a compressed video data sequence containing one or more coded pixel blocks. The compressed video sequence is buffered. Prediction information for each of the coded pixel blocks is reviewed. One or more groups of coded pixel blocks are formed based on the reviewed prediction information such that the coded pixel blocks within a given group have similar prediction dependencies and/or at least do not depend on a reconstructed pixel within a group of received pixel blocks to enable parallel decoding. The formed groups are scheduled for processing and subsequently decoded to produce a decoded video data sequence.
