摘要： A semiconductor device structure includes a region of semiconductor material with a first major surface and an opposing second major surface. A contact structure is disposed in a first portion of the region of semiconductor material and includes a tub structure extending from adjacent a first portion of the first major surface. A plurality of structures comprising portions of the region of semiconductor material extend outward from a lower surface of the tub structure. In some embodiments, the plurality of structures comprises a plurality of free-standing structures. A conductive material is disposed within the tub structure and laterally surrounding the plurality of structures. In one embodiment, the contact structure facilitates the fabrication of a monolithic series switching diode structure having a low-resistance substrate contact.

摘要： In one embodiment, a semiconductor device may include a first transistor having a first current carrying electrode, a second current carrying electrode, and a control electrode; a first bipolar transistor having a collector coupled to the first current carrying electrode of the first transistor, a base coupled to the second current carrying electrode of the first transistor, and an emitter of the first bipolar transistor coupled to a first node of the semiconductor device. In an embodiment, the first node is connected to a terminal of a semiconductor package. An embodiment may include a semiconductor component coupled between the base of the first bipolar transistor and the emitter of the second bipolar transistor.
