Formation of titanium oxide thin films by reactive magnetron sputtering

Abstract

The article presents the results of studies of the dielectric characteristics of titanium oxide films deposited by reactive magnetron sputtering of a Ti target in an Ar/O2 gas mixture. Dependencies of dielectric constant, dielectric loss tangent, band gap, leakage current density on oxygen content in Ar/O2 gas mixture during film deposition were established. Films with a dielectric constant of 20-30 units, a dielectric loss tangent of 0,02, a band gap of 3,82 eV, a leakage current density of less than 1,0 A/cm2 at an electric field strength of 2,0*106 V/cm, were obtained.
