  • Patent number: 11121134
    Abstract: A semiconductor device includes a device isolation layer defining first and second active regions, a buried contact connected to the second active region, and first and second bit line structures disposed on the first and second active regions. Each of the first and second bit line structures comprises a bit line contact part and a bit line pass part. The bit line contact part is electrically connected to the first active region. The bit line pass part is disposed on the device isolation layer. A height of a lowest part of the buried contact is smaller than a height of a lowest part of the bit line pass part. The height of the lowest part of the buried contact is greater than a height of a lowest part of the bit line contact part. A lower end of the bit line pass part is buried in the second active region.

  • Publication number: 20210123567
    Abstract: A system and a method for sensing hydrogen charge state of a fuel cell electric vehicle are provided. The system includes an infrared transmission unit that transmits a fuel door sensing infrared signal for sensing a fuel door opened while charging hydrogen and a nozzle sensing infrared signal for sensing a charging station-side hydrogen charging nozzle connected to a hydrogen charging inlet of a vehicle. An infrared reception unit receives the fuel door sensing infrared signal and thereafter, reflected on a fuel door and the nozzle sensing infrared signal transmitted from the infrared transmission unit and thereafter, reflected on the hydrogen charging nozzle. A controller determines that the vehicle is being charged with hydrogen when sensing an open state of the fuel door and a hydrogen charging inlet connection state of the hydrogen charging nozzle.

  • Patent number: 9902288
    Abstract: An apparatus is provided for safely discharging hydrogen permeated and leaking from a fuel tank of a fuel cell vehicle. The hydrogen exhaust apparatus for a fuel cell vehicle collects and safely processes hydrogen permeating a tank, and quantitatively detects the hydrogen transmissive amount. Thus the apparatus has improved a shape and attachment manner of a dome protector mounted in a hydrogen fuel tank. The safety aspect of hydrogen discharged to the air is improved, and an active response to various controls by quantitatively detecting the hydrogen transmissive amount is implemented.

  • Patent number: 9845014
    Abstract: A system control method is provided for measuring a distance between a smart key and a vehicle. When the distance between the smart key and the vehicle is changed based on a predetermined distance whether a hydrogen leak occurs is detected by a hydrogen sensor detection controller. A driver is then informed of a hydrogen leak via a display on a cluster, a turn-on of an emergency light, and a warning sound of the vehicle. Alternatively, a starting-impossible state of the vehicle or shutting-down starting of the vehicle is maintained to ensure safety measures based on the concentration of the leaking hydrogen.
