Abstract:
(EN) A sputtering target provided with an oxide sintered compact including a spinel structure compound containing indium element (In), tin element (Sn), zinc element (Zn), an element X, and oxygen, the atomic ratios of the elements satisfying formula (1), and the spinel structure compound furthermore being represented by the formula Zn2SnO4. (1): 0.001 ≤ X/(In + Sn + Zn + X) ≤ 0.05. (In formula (1), In, Zn, Sn, and X represent the amounts of indium element, zinc element, tin element, and element X, respectively, contained in the oxide sintered compact. Element X is at least one species selected from Ge, Si, Y, Zr, Al, Mg, Yb, and Ga.)
(FR) L'invention concerne une cible de pulvérisation pourvue d'un compact fritté d'oxyde comprenant un composé à structure de spinelle contenant un élément indium (In), un élément étain (Sn), un élément zinc (Zn), un élément X et de l'oxygène, les rapports atomiques des éléments satisfaisant la formule (1), et le composé de structure de spinelle étant en outre représenté par la formule Zn2SnO4. (1) : 0,001 ≤ X/ (In + Sn + Zn + X) ≤ 0,05. (Dans la formule (1), In, Zn, Sn et X représentent les quantités respectives d'élément indium, d'élément zinc, d'élément étain et d'élément X contenus dans le compact fritté d'oxyde. L'élément X est au moins une espèce choisie parmi Ge, Si, Y, Zr, Al, Mg, Yb et Ga).
(JA) インジウム元素(In)、スズ元素(Sn)、亜鉛元素(Zn)、X元素、および酸素を含有し、各元素の原子比が下記式(1)を満たし、さらにZn2SnO4で表されるスピネル構造化合物を含む、酸化物焼結体を備える、スパッタリングターゲット。 0.001≦X/(In+Sn+Zn+X)≦0.05 ・・・(1) (式(1)中、In、Zn、SnおよびXは、それぞれ酸化物焼結体中のインジウム元素、亜鉛元素、スズ元素およびX元素の含有量を表す。X元素は、Ge、Si、Y、Zr、Al、Mg、Yb、およびGaから少なくとも1種以上が選択される。)
