    Abstract: A semiconductor device and a method of making a semiconductor device. The device includes a semiconductor substrate having a first conductivity type, a layer of doped silicon located on the substrate, a trench extending into the layer of silicon, and a gate electrode and gate dielectric located in the trench. The device also includes a drain region, a body region having a second conductivity type located adjacent the trench and above the drain region, and a source region having the first conductivity type located adjacent the trench and above the body region. The layer of doped silicon in a region located beneath the body region includes donor ions and acceptor ions forming a net doping concentration within said region by compensation. The net doping concentration of the layer of doped silicon as a function of depth has a minimum in a region located immediately beneath the body region.

    Abstract: A method to manufacture a vertical capacitor region that comprises a plurality of trenches, wherein the portions of the semiconductor region in between the trenches comprise an impurity. This allows for the trenches to be placed in closer vicinity to each other, thus improving the capacitance per unit area ratio. The total capacitance of the device is defined by two series components, that is, the capacitance across the dielectric liner, and the depletion capacitance of the silicon next to the trench. An increase of the voltage on the capacitor increases the depletion in the silicon and the depletion capacitance as a result, such that the overall capacitance is reduced. This effect may be countered by minimizing the depletion region which may be achieved by ensuring that the silicon adjacent to the capacitor is as highly doped as possible.

    Abstract: Embodiments relate to a diode circuit which uses a Schottky diode. A parallel bypass branch has a switch and bypass diode in series. The operation of the switch is dependent on the voltage across the Schottky diode so that the bypass function is only effective when a desired voltage is reached. The diode circuit can be used as a replacement for a single diode, and provides bypass current protection preferably without requiring any external control input.
