Abstract:
A multi-path transistor includes an active region including a channel region and an impurity region. A gate is dielectrically separated from the channel region. A signal line is dielectrically separated from the impurity region. A conductive shield is disposed between, and dielectrically separated from, the signal line and the channel region. In some multi-path transistors, the channel region includes an extension-channel region under the conductive shield and the multi-path transistor includes different conduction paths, at least one of the different conduction paths being in the extension-channel region to conduct substantially independent of a voltage on the signal line. In other multi-path transistors, the conductive shield is operably coupled to the impurity region and the multi-path transistor includes different conduction paths, at least one of the different conduction paths being under the conductive shield to conduct substantially independent of a voltage on the signal line.
