Abstract: An electronic device includes an n-channel transistor and a p-channel transistor. The p-channel transistor has a first gate electrode with a first work function and a first channel region including a semiconductor layer immediately adjacent to a semiconductor substrate. In one embodiment, the first work function is less than the valence band of the semiconductor layer. In another embodiment, the n-channel transistor has a second gate electrode with a second work function different from the first work function and closer to a conduction band than a valence band of a second channel region. A process of forming the electronic device includes forming first and second gate electrodes having first and second work functions, respectively. First and second channel regions having a same minority carrier type are associated with the first and second gate electrodes, respectively.

Abstract: A device structure and method for forming the device structure has a semiconductor substrate with an overlying first metal oxide layer, an overlying intermediate layer with a first metal and either nitrogen or carbon, and an overlying second metal oxide layer. Oxygen is then provided to the intermediate layer. The oxygen has the effect of changing the intermediate layer from a conducting layer to a dielectric layer. A final device may then be formed, for example, by forming a gate and two current electrodes.
