Compound, high-K, gate and capacitor insulator layer

摘要

A gate or capacitor insulator structure using a first grown oxide layer, a high-k dielectric material on the grown oxide layer, and a deposited oxide layer on the high-k dielectric material. The deposited oxide layer is preferably a densified deposited oxide layer. A conducting layer, such as a gate or capacitor plate, may overlay the densified oxide layer.
