In this paper we present the electrical performance of MOS capacitors with ZrO2 gate dielectric prepared by e-beam evaporation of zirconium and yttrium stabilized zirconia (YSZ) and subsequent thermal treatment. To this stage we have reached an equivalent oxide thickness (EOT) of 1.9 nm. The effect of post-oxidation annealing on Zr incorporation into the Si substrate is investigated. SIMS analysis showed no signs of Zr diffusion in the substrate at temperatures as high as 900°C and that significant diffusion occurs only at 1100°C
