    摘要: A high voltage P-N diode includes a P.sup.- substrate with a thin N.sup.- epitaxial layer thereon. An N.sup.+ cathode region extends into the N.sup.- epitaxial layer from the upper surface thereof. A P.sup.+ anode region extends into the N.sup.- epitaxial layer from its upper surface and surrounds the N.sup.+ cathode region. An N.sup.+ buried layer is situated between the P.sup.- substrate and the N.sup.- epitaxial layer, beneath the P.sup.+ anode region, and surrounds the N.sup.+ cathode region, as viewed from above. A further P.sup.+ region extends into the N.sup.- epitaxial layer from its upper surface and surrounds the N.sup.+ cathode region, and, in turn, is surrounded by the P.sup.+ anode region. In an exemplary embodiment, a MOSFET is included to alternately connect the further P.sup.+ region to the P.sup.- substrate and to open circuit the further P.sup.+ region. With the further P.sup. + region open circuited, the P-N diode has a low on-resistance when it operates in its current-conducting state. An embodiment structurally similar to the P-N diode comprises a bipolar transistor having an N.sup.+ emitter region extending into a P.sup.+ base region, which corresponds to the P.sup.+ anode region of the diode.

    摘要: An integrated circuit in which a large potential can be maintained between the source of the device and the substrate on which this device and other devices are fabricated is described. The circuit employs a minority carrier sink region to remove minority carriers from the gate region of a MOS depletion device. The sink region is shielded from the substrate by a buried layer which prevents punch-through between the sink region and the substrate.

    摘要: A semiconductor wafer having a substrate with an epitaxial layer thereon includes a semiconductor device electrically isolated from the substrate as well as from any other devices in the wafer by electrical isolation structure comprising semiconductor material.

The N+ high voltage tub comprises an N+ high voltage region situated in the epitaxial layer and surrounding a device region in which the semiconductor device is at least partially contained and, further, an N+ buried layer underlying the N+ high voltage region and the entirety of the device region.

    摘要: A power semiconductor device incorporates in its active, or current-carrying, region a main current section and an emulation current section. The active region is surrounded by a common device termination region. This is accomplished through provision of respective separate cathodes for the main and emulation current regions, while the device anode is common to both the main and emulation current sections. The current level in the emulation current section provides an accurate representation of the current level in the main current section since the main and emulation current sections are closely coupled both thermally and electrically and, further, are formed in the same fabrication process. The current level in the main current section can be economically determined with low power circuitry by way of sensing the current level in the emulation current section.
