Abstract :
Films of yttrium oxide (Y2O3) were deposited on Si substrates from a Y2O3 target by RF magnetron sputtering. MIS capacitors in the form of Al and Y2O3 (400 Å)-Si were then fabricated. The leakage current density was about 10-6 A/cm2 at 1.3×106 V/cm, and the breakdown field of the films was about 2.75×106 V/cm. The dielectric constant of the sputtered Y2O3 was found to be about 12-12.7
