Cadmium-tin oxide films deposited by rf sputtering from a CdO-SnO2 target

Abstract
Cadmium‐tin oxide (CTO) films with high conductivity and high transparency were prepared by rf sputtering from a CdO‐SnO2 target in an Ar or Ar‐O2 atmosphere. The resistivity of CTO films was 6.5×10−4 Ω in the film thickness range of 2500–15000 Å, and the average transmission was 90% over the visible region.
