  • Publication number: 20140060251
    Abstract: A method for the direct reduction of metal oxides with carbon. According to the method, pellets are formed containing a mixture of metal oxides having sequential reduction potentials when heated in the presence of carbon and an amount of carbon sufficient to reduce more easily reduced of the metal oxides yet insufficient to reduce all of the metal oxides. The pellets are heated to a temperature at least sufficient to reduce the more easily reduced metal oxides to produce direct reduction metal while removing sufficient of the carbon in the form of oxides of carbon during the reduction to avoid a subsequent decarburization step in further processing of the direct reduction metal.

  • Publication number: 20120026080
    Abstract: An electronic device and a method enables an unlock operation of the electronic device. When the electronic device in a lock state is moved for the unlock operation, the electronic device receives a three-axis acceleration vector of the electronic device from an accelerometer. The electronic device analyzes three movement directions of the electronic device along three coordinate axes. The electronic device determines whether the analyzed three movement directions are the same as three predetermined movement directions along the three coordinate axes. If the analyzed three movement directions are the same as the three predetermined movement directions along the three coordinate axes, the electronic device is changed from the lock state to an unlock state.

  • Publication number: 20120018786
    Abstract: A semiconductor device is formed by a multi-step etching process that produces trench openings in a silicon substrate immediately adjacent transistor gate structures formed over the substrate surface. The multi-step etching process is a Br-based etching operation with one step including nitrogen and a further step deficient of nitrogen. The etching process does not attack the transistor structure and forms the openings. The openings are bounded by upper surfaces that extend downwardly from the substrate surface and are substantially vertical, and lower surfaces that bulge outwardly from the upper vertical sections and undercut the transistor structure. The openings may be filled with a suitable source/drain material to produce SSD transistors with desirable Idsat characteristics.

  • Patent number: 8071481
    Abstract: A multi-step etching process produces trench openings in a silicon substrate that are immediately adjacent transistor structures formed over the substrate surface. The multi-step etching process is a Br-based etching operation with one step including nitrogen and a further step deficient of nitrogen. The etching process does not attack the transistor structure and forms an opening bounded by upper surfaces that extend downwardly from the substrate surface and are substantially vertical, and lower surfaces that bulge outwardly from the upper vertical sections and undercut the transistor structure. The aggressive undercut produces a desirable stress in the etched silicon surface. The openings are then filled with a suitable source/drain material and SSD transistors with desirable Idsat characteristics may then be formed.
