Abstract

This sintered body, which contains zinc (Zn), tin (Sn) and / or indium (In), magnesium (Mg), and oxygen (O), is an oxide sintered body characterized by having a total content of Sn and / or In in terms of SnO2 and / or In2O3 of 10-90 mol%, having an Mg content in terms of MgF2 of 15-50 mol% when the ratio of the number of Sn and / or In atoms to the number of Zn atoms is no greater than 1, and having an Mg content in terms of MgF2 of 1-40 mol% when the ratio of the number of Sn and / or In atoms to the number of Zn atoms is at least 1. The sintered body can form an amorphous film by means of a sputtering method or an ion plating method, and so has a superior effect in being able to suppress the occurrence of cracking or peeling of the film resulting from membrane stress. The thin film of the present invention is particularly useful as an optical thin film forming a protective layer for an optical information recording medium, an organic EL television thin film, and a transparent electrode thin film.

Description

technical field

[0001] The present invention relates to a sintered body capable of obtaining a transparent conductive film with good visible light transmittance and conductivity, and an amorphous film with a low refractive index produced using the sintered body. Background technique

[0002] Conventionally, an ITO (indium tin oxide) film, which is a transparent conductive film in which tin is added, is transparent and has excellent conductivity, and has been used in a wide range of applications such as various displays. However, since indium which is a main component is expensive in this ITO, there exists a problem that it is inferior in terms of manufacturing cost.

[0003] Based on this, films using, for example, zinc oxide (ZnO) as a substitute for ITO have been proposed. Since the film is mainly composed of zinc oxide, it has an advantage of being inexpensive. Such a film is known to have increased conductivity due to oxygen deficiency of ZnO as the main component. If ...
