Cadmium–tin-oxide films deposited by dc reactive sputtering from a Cd-Sn alloy target

Abstract
Cadmium–tin‐oxide films with high conductivity and high visible transmission were prepared by dc reactive sputtering from a Cd‐Sn alloy target in an Ar‐O2 atmosphere. The electrical and optical properties of these films were found to depend strongly uponthe oxygen concentration in an Ar‐O2 atmosphere during deposition. Films with a lowest resistivity of 2.0×10−4 Ω cm and a highest transmission of 90% over the visible region have been obtained for a 6% oxygen concentration in an Ar‐O2 atmosphere.
