摘要:
A field effect transistor device and method which includes a semiconductor substrate, a dielectric gate layer, preferably a high dielectric constant gate layer, overlaying the semiconductor substrate and an electrically conductive oxygen barrier layer overlaying the gate dielectric layer. Sn one embodiment, there is a conductive layer between the gate dielectric layer and the oxygen barrier layer, In another embodiment, there is a low resistivity metal layer on the oxygen barrier layer.
