  • Publication number: 20170175623
    Abstract: One of the objects of the invention is to provide a water-saving type advanced humid air gas turbine system (AHAT) that can decrease the amount of makeup water to be supplied from the outside, by reducing the amount of water consumed when the gas turbine system is starting up, shut down, or subjected to load rejection. The gas turbine system includes a compressor, the compressed air header for generating humidified combustion air, a combustor for generating combustion gas, and the turbine. When the gas turbine system is starting up, shut down or subjected to load rejection, steam coming from the heat recovery steam generator is recovered by blocking the first steam system and making the second steam system communicate with the heat recovery steam generator.

  • Patent number: 9412755
    Abstract: In a manufacturing method for a semiconductor device provided with a MONOS-type FET for a non-volatile memory and high-voltage and low-voltage MOSFETs, a groove having a predetermined depth is formed in a region in which the high-voltage MOSFET on a semiconductor substrate is formed, and an oxide film serving as a gate insulating film of the high-voltage MOSFET is formed within the formed groove by thermal oxidation. Thereafter, a gate electrode film of the low-voltage MOSFET is formed on the entire surface of the semiconductor substrate. Thereafter, a region for the MONOS-type FET is opened, the semiconductor surface of the semiconductor substrate is exposed, and a first potential barrier film, a charge storage film, and a second potential barrier film are sequentially deposited, to thereby form a charge storage three-layer film. Agate electrode film of the MONOS-type FET is formed on the formed charge storage three-layer film.

  • Patent number: 9412599
    Abstract: A gate oxide film is formed in a region having a MOSFET on a semiconductor substrate formed therein, and a first polysilicon film serving as a gate electrode of the MOSFET is further formed. Thereafter, a charge storage three-layer film is formed by opening a region having a MONOS type FET formed therein, exposing a semiconductor surface of the semiconductor substrate, and sequentially depositing a first potential barrier film, a charge storage film, and a second potential barrier film. In this case, before the charge storage three-layer film is formed, an anti-oxidation film is formed on the first polysilicon film.

  • Patent number: 9390765
    Abstract: The SRAM memory cell includes a metal wiring line having a titanium or tantalum film in a bottom layer, and a via having a tungsten plug. The via is arranged on the metal line following a layout rule which permits the misalignment. In arranging the upper-layer via with a tungsten plug on the metal line, one side of the via is disposed to be adjacent to one end of the metal line with a margin smaller than an alignment accuracy, and the lower-layer via is laid out far away from the end of the metal line as possible. The reduction in the yield, caused by the problem of the contact with the lower-layer via being broken or increased in resistance at occurrence of misalignment, can be suppressed.
