  • Publication number: 20190267492
    Abstract: A semiconductor device includes an oxide semiconductor layer, disposed over a substrate. A source electrode of a metal nitride is disposed on the oxide semiconductor layer. A drain electrode of the metal nitride is disposed on the oxide semiconductor layer. A metal-nitride oxidation layer is formed on a surface of the source electrode and the drain electrode. A ratio of a thickness of the metal-nitride oxidation layer to a thickness of the drain electrode or the source electrode is equal to or less than 0.2.

  • Patent number: 5302083
    Abstract: A ceiling fan comprising upper and lower transparent dome-shaped light housings connected together by an annular ring. A neon light is positioned about the fan motor between the light housings such that illumination from the neon tube shines therethrough. Power supply electrical wires extend from the ceiling through the down rod of the fan, then through the hollow shaft of the motor into a switch housing. A light circuit is positioned within the switch housing and connected to the power supply electrical wires. High voltage electrical wires extend from the light circuit through the hollow shaft and to the neon light for powering the neon tube to cause illumination thereof.
