    摘要: A trench type power MOSgated device has a plurality of spaced trenches lined with oxide and filled with conductive polysilicon. The tops of the polysilicon fillers are below the top silicon surface and are capped with a deposited oxide the top of which is flush with the top of the silicon. Source regions of short lateral extent extend into the trench walls to a depth below the top of the polysilicon. A trench termination is formed having an insulation oxide liner covered by a polysilicon layer, covered in turn by a deposited oxide.

    摘要: According to one exemplary embodiment, a rectifier circuit includes a diode. A first depletion-mode transistor is connected to a cathode of the diode. Also, at least one second depletion-mode transistor is in parallel with the first depletion-mode transistor and is configured to supply a pre-determined current range to a cathode of the diode. A pinch off voltage of the at least one second depletion-mode transistor can be more negative than a pinch off voltage of the first depletion-mode transistor and the at least one second depletion-mode transistor can be configured to supply the pre-determined current range while the first depletion-mode transistor is OFF. Also, the pre-determined current range can be greater than a leakage current of the first depletion-mode transistor.
