摘要： A semiconductor structure includes multiple semiconductor devices on a substrate and a metal layer disposed over the semiconductor devices, the metal layer comprising at least a first trace and a second trace. A conductive pillar is disposed directly on and in electrical contact with the first trace of the metal layer, and a dielectric layer is selectively disposed between the metal layer and the conductive pillar, where the dielectric layer electrically isolates the second trace from the pillar. A moisture barrier surrounds the semiconductor devices around a periphery of the semiconductor structure, and extends from the substrate through the dielectric layer to the conductive pillar.

摘要： A switching device has an input node, an output node, and a control node. The device includes: a substrate having a first side and a second side with a ground plane on the first side of the substrate and a mesa on the second side of the substrate. The mesa is made of a normally-conductive semiconductor material, and an isolation region substantially surrounds the mesa. A field effect transistor (FET) is on the mesa. The FET has an input terminal connected to the input node, an output terminal connected to the output node, and a gate. A capacitor is connected in series between the output terminal of the FET and the gate, and a resistor is connected in series between the control node and the gate. A gate electrode is directly connected to the gate. The gate electrode is disposed substantially entirely on the mesa.
