Problems solved by technology

However, this material is a crystalline film, and the effect of an amorphous film as in the present invention described later cannot be obtained.
In addition, Patent Document 5 discloses an amorphous transparent conductive film with a small refractive index and low specific resistance, but it is different from the composition system of the present invention, and there is a problem that the refractive index and the resistance value cannot be adjusted at the same time.

Abstract

The invention provides a sintered compact and an amorphous film. The sintered compact is characterized by comprising zinc (Zn), trivalent metal elements, germanium (Ge) and / or silicon (Si), and oxygen (O), wherein, if the total content of the trivalent metal elements is A mol% in terms of oxides and the total content of Ge and or Si is B mol% in terms of GeO2 and / or SiO2, 15<=A+B<=70. According to the invention, the sintered compact has low bulk resistance and is capable of performing DC sputtering. The sintered compact can be used to form the amorphous film with a low refractive index.

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, as a transparent conductive film, an ITO (Indium-Tin-oxide) film obtained by adding tin to indium oxide 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, this ITO has a problem in terms of manufacturing cost. [0003] In view of the above circumstances, a film using, for example, zinc oxide (ZnO) has been proposed as a substitute for ITO. A film containing zinc oxide as a main component has the advantage of being inexpensive. It is known that this film has a phenomenon in which the conductivity is enhanced due to the oxygen deficiency ...
