Patent ID: 7790644

Claim:
A zinc-oxide-based sputtering target or a zinc-oxide-based ion-plating target, comprising zinc oxide as a predominant component, and both titanium (Ti) and gallium (Ga), wherein a titanium content x (at. %) and a gallium content y (at. %) satisfy the following conditions: the titanium content (x) is 1.1 at. % or more, or the gallium content (y) is 4.5 at. % or more; the gallium content (y) (at. %) is equal to or less than (−2.5x+9.8); the gallium content (y) (at. %) is equal to or greater than (−0.5x+1.1), excepting the case where the titanium content (x) or the gallium content (y) is 0 (at. %); and the gallium content y (at. %) is equal to or less than (−x+3.4); or the gallium content (y) (at. %) is equal to or less than (x−0.9).
