  • Thin-film transistor and zinc oxide-based sputtering target for the same
    Patent number: 9035297
    Abstract: A thin-film transistor includes a metal electrode and a zinc oxide-based barrier film that blocks a material from diffusing out of the metal electrode. The zinc oxide-based barrier film is made of zinc oxide doped with indium oxide, the content of the indium oxide ranging, by weight, 1 to 50 percent of the zinc oxide-based barrier film. A zinc oxide-based sputtering target for deposition of a barrier film of a thin-film transistor is made of zinc oxide doped with indium oxide, the content of the indium oxide ranging, by weight, 1 to 50 percent of the zinc oxide-based sputtering target.

  • ZINC OXIDE-BASED SPUTTERING TARGET, METHOD OF MANUFACTURING THE SAME, AND THIN-FILM TRANSISTOR HAVING BARRIER LAYER DEPOSITED USING THE SAME
    Publication number: 20130341181
    Abstract: A zinc oxide (ZnO)-based sputtering target, a method of manufacturing the same, and a thin-film transistor (TFT) having a barrier layer deposited using the same. The zinc oxide-based sputtering target includes a sinter containing zinc oxide doped with gallium oxide, the content of the gallium oxide ranging, by weight, from 10 to 50 percent of the sinter, and a backing plate bonded to the rear surface of the sinter to support the sinter. The zinc oxide-based sputtering target can be subjected to direct current (DC) sputtering, and improve the contact and etching characteristics of a barrier layer that is deposited using the same.
