    Abstract: Disclosed is a method for manufacturing a power semiconductor device. The method includes forming a lower active layer on a substrate, forming an upper active layer on both sides of the lower active layer, forming a source electrode, a drain electrode, and a gate electrode on the upper active layer and the lower active layer, and forming a heat dissipating and electrical ground electrode penetrating the substrate and the lower active layer and connected to a lower surface of the lower active layer. The upper active layer may be epitaxially grown at a high doping concentration by a selective deposition method using a mask layer that exposes a portion of the lower active layer as a blocking layer.

    Abstract: A field effect transistor includes an active layer and a capping layer sequentially stacked on a substrate, and a gate electrode penetrating the capping layer and being adjacent to the active layer. The gate electrode includes a foot portion adjacent to the active layer and a head portion having a width greater than a width of the foot portion. The foot portion of an end part of the gate electrode has a width less than a width of the head portion of another part of the gate electrode and greater than a width of the foot portion of the another part of the gate electrode. The foot portion of the end part of the gate electrode further penetrates the active layer so as to be adjacent to the substrate.

    Abstract: A cascode switch circuit includes a first transistor, a second transistor, and a protector. A first transistor receives a signal from a first terminal through a first end and transfers the signal to a second end in response to a first control signal. A second transistor delivers the signal that the first transistor transfers to a second terminal in response to a second control signal. A protector is connected between a gate of the first transistor and the second terminal. The first control signal is provided to allow the first transistor to operate in a normally-on state. The second control signal is provided to allow the second transistor to operate in a normally-off state.
