The effect of a thin Si layer insertion at W/La 2 O 3 interface on the electrical characteristics of MOS capacitors and transistors is investigated. A suppression in the EOT increase can be obtained with Si insertion, indicating the inhibition of diffusion of oxygen atoms into La 2 O 3 layer by form
