Indium Oxide Transparent Conductive Film

摘要

An indium oxide sintered compact containing zirconium as an additive, wherein the ratio of atomic concentration of zirconium to the sum of the atomic concentration of indium and the atomic concentration of zirconium is in the range of 0.5 to 4%, the relative density is 99.3% or higher, and the bulk resistance is 0.5 mΩ·cm or less. An indium oxide transparent conductive film of high transmittance in the visible light region and the infrared region, with low film resistivity, and in which the crystallization temperature can be controlled, as well as the manufacturing method thereof, and an oxide sintered compact for use in producing such transparent conductive film are provided.
