摘要： The present disclosure relates to a bipolar junction transistor (BJT) structure that significantly reduces current crowding while improving the current gain relative to conventional BJTs. The BJT includes a collector, a base region, and an emitter. The base region is formed over the collector and includes at least one extrinsic base region and an intrinsic base region that extends above the at least one extrinsic base region to provide a mesa. The emitter is formed over the mesa. The BJT may be formed from various material systems, such as the silicon carbide (SiC) material system. In one embodiment, the emitter is formed over the mesa such that essentially none of the emitter is formed over the extrinsic base regions. Typically, but not necessarily, the intrinsic base region is directly laterally adjacent the at least one extrinsic base region.

摘要： A negative bevel edge termination for a Silicon Carbide (SiC) semiconductor device is disclosed. In one embodiment, the negative bevel edge termination includes multiple steps that approximate a smooth negative bevel edge termination at a desired slope. More specifically, in one embodiment, the negative bevel edge termination includes at least five steps, at least ten steps, or at least 15 steps. The desired slope is, in one embodiment, less than or equal to fifteen degrees. In one embodiment, the negative bevel edge termination results in a blocking voltage for the semiconductor device of at least 10 kilovolts (kV) or at least 12 kV. The semiconductor device is preferably, but not necessarily, a thyristor such as a power thyristor, a Bipolar Junction Transistor (BJT), an Insulated Gate Bipolar Transistor (IGBT), a U-channel Metal-Oxide-Semiconductor Field Effect Transistor (UMOSFET), or a PIN diode.

摘要： A metal-insulator-semiconductor field-effect transistor (MISFET) includes a SiC layer with source and drain regions of a first conductivity type spaced apart therein. A first gate insulation layer is on the SiC layer and has a net charge along an interface with the SiC layer that is the same polarity as majority carriers of the source region. A gate contact is on the first gate insulation layer over a channel region of the SiC layer between the source and drain regions. The net charge along the interface between the first gate insulation layer and the SiC layer may deplete majority carriers from an adjacent portion of the channel region between the source and drain regions in the SiC layer, which may increase the threshold voltage of the MISFET and/or increase the electron mobility therein.

摘要： Methods and constructs are provided for controlling processes in live animals, plants or microbes via genetically engineered near-infrared light-activated or light-inactivated proteins including chimeras including the photosensory modules of bacteriophytochromes and output modules that possess enzymatic activity and/or ability to bind to DMA, RNA, protein, or small molecules. DNA encoding these proteins are introduced as genes into live animals, plants or microbes, where their activities can be turned on by near-infrared light, controlled by the intensity of light, and turned off by near-infrared light of a different wavelength than the activating light. These proteins can regulate diverse cellular processes with high spatial and temporal precision, in a nontoxic manner, often using external light sources. For example, near-infrared light-activated proteins possessing nucleotidyl cyclase, protein kinase, protease, DNA-binding and RNA-binding activities are useful to control signal transduction, cell apoptosis, proliferation, adhesion, differentiation and other cell processes.
