Abstract
An enhancement-depletion-mode inverter includes a load transistor and a drive transistor. The load transistor has a top gate architecture with a first source, a first drain, a load channel region, a first semiconductor layer, and a first gate electrode. A load gate dielectric is in the load channel region, and has a load dielectric thickness. The load transistor is configured to operate in a depletion mode. The drive transistor has a bottom gate architecture with a second source, a second drain, a drive channel region, a second semiconductor layer, and a second gate electrode. A drive gate dielectric is in the drive channel region, and has a drive dielectric thickness that is different from the load dielectric thickness. The drive transistor is configured to operate in a normal mode or an enhancement mode. The first source is electrically connected to the second drain and the first gate.
