  • Patent number: 9707507
    Abstract: The present invention provides ammonia purification means to remove impurities such as oil with a negative effect on vapor deposition from inexpensive commercially available industrial crude ammonia and from crude ammonia recovered from the gallium nitride compound semiconductor process and to continuously supply the purified ammonia to the gallium nitride compound semiconductor process. The oil removing device removing oil from crude ammonia containing oil as impurities includes an oil filter cylinder accommodating a filtration element cylindrically formed from a filtration membrane processed into a shape of pleat, honeycomb, or space structure; and an oil adsorption cylinder filled with activated carbon. The ammonia purification apparatus is provided with the oil removing device; a catalyst cylinder filled with a catalyst containing nickel as an active component; and an adsorption cylinder filled with synthetic zeolite.

  • Publication number: 20170053947
    Abstract: A thin-film transistor includes an oxide semiconductor layer, a gate insulating film, a gate electrode, and a source-drain electrode. The oxide semiconductor layer includes a channel region and a low-resistance region that has an electric resistance lower than an electric resistance of the channel region. The gate insulating film is provided on the oxide semiconductor layer. The gate electrode is provided on the gate insulating film and opposed to the channel region of the oxide semiconductor layer. The gate electrode includes a first electrode layer and a second electrode layer in order from the gate insulating film. The first electrode layer has a first width that is along a channel length and greater than a second width of the second electrode layer along the channel length. The source-drain electrode is electrically coupled to the low-resistance region of the oxide semiconductor layer.
