Latest Patents
One of Wohlmuth's latest patents is titled "Monolithic integrated enhancement mode and depletion mode field effect transistors and method of making the same." This invention involves a depletion mode (D-mode) field effect transistor (FET) that is monolithically integrated with an enhancement mode (E-mode) FET in a multi-layer structure. The multi-layer structure consists of a channel layer overlaid by a barrier layer, which is further overlaid by an ohmic contact layer. The source and drain contacts of both the D-mode and E-mode FETs are coupled to the ohmic contact layer, while the gate contacts are connected to the barrier layer. An amorphized region is created beneath the E-mode gate contact within the barrier layer, forming a buried E-mode Schottky contact. An alternative embodiment of this invention couples the gate contact of the D-mode transistor to a first layer that overlies the barrier layer, providing a similar D-mode amorphized region within that layer.
