  • Patent number: 7049656
    Abstract: A semiconductor configuration includes a semiconductor body with a first connection zone of a first conductivity type, a second connection zone of the first conductivity type, a channel zone of the first conductivity type, and at least one control electrode surrounded by an insulation layer. The channel zone is formed between the first connection zone and the second connection zone. The at least one control electrode extends, adjacent to the channel zone, from the first connection zone to the second connection zone. The first connection zone, the second connection zone and the at least one control electrode extend in the vertical direction such that, when a voltage is applied between the first and second connection zones, a current path along the lateral direction is formed in the channel zone.

  • Patent number: 7038272
    Abstract: In a method for forming a channel zone in field-effect transistors, a polysilicon layer is patterned above the channel zone to be formed. The polysilicon layer serves as a mask substrate for the subsequent doping of the channel zone. The expedient patterning of the polysilicon layer with holes in a gate region and pillars in a source region enables the channel zone to be doped more lightly. In another embodiment, the novel method is used for a channel width shading of a PMOS transistor cell.

  • Patent number: 6912153
    Abstract: A memory cell stores data permanently in a memory material that can assume a first, high-resistance state and a second, low-resistance state, that is in a phase-changeable or ovonic material. A heating device is disposed to heat the memory material at different rates to a programming temperature. The memory material either has a high resistance or a low resistance after cooling, depending on the heating rate. The heating device has a switching device and a heating element in immediate vicinity to the memory material. The switching device has a field-effect transistor and a drain region of the field-effect transistor forms the heating element. Alternatively, the heating element includes a diode or a diode chain.

    Abstract: A semiconductor element has a semiconductor body of a first conductivity type. The semiconductor body has a zone of a second conductivity type embedded. Further regions of the second conductivity type surround the zone of the second conductivity type like a well.

  • Patent number: 6870201
    Abstract: The invention relates to a high voltage resistant edge structure in the edge region of a semiconductor component which has floating guard rings of the first conductivity type and inter-ring zones of the second conductivity type which are arranged between the floating guard rings, wherein the conductivities and/or the inter-ring zones are set such that their charge carriers are totally depleted when blocking voltage is applied. The inventive edge structure achieves a modulation of the electrical field both at the surface and in the volume of the semiconductor body. If the inventive edge structure is suitably dimensioned, the field intensity maximum can easily be situated in the depth; that is, in the region of the vertical p-n junction. Thus, a suitable edge construction which permits a “soft” leakage of the electrical field in the volume can always be provided over a wide range of concentrations of p and n doping.

    Abstract: The controllable semiconductor switching element blocks in both directions. The semiconductor switching element is formed with a first conduction region and a second conduction region of a first type of conductivity, a blocking region of a second type of conductivity which is disposed between the first and second conducting regions, and a control electrode which is arranged opposite the blocking region and insulated from it. A recombination region is configured in the blocking region and is comprised of a material that promotes a recombination of charge carriers of the first and second type of conductivity.

  • Patent number: 6847091
    Abstract: A vertical semiconductor component having a semiconductor body of a first conductivity type is described. In a surface region of the semiconductor body, at least one zone of a second conductivity type, opposite to the first conductivity type, is embedded.

  • Publication number: 20040212419
    Abstract: The invention relates to a MOSFET circuit having reduced output voltage oscillations, in which a smaller CoolMOS transistor (T2) with a zener diode (Z1) connected upstream of its gate is located in parallel with a larger CoolMOS transistor (T1), so that, during a switch-off operation, after the larger transistor has been switched off, the smaller transistor (T2) carries a tail current on account of the zener voltage still present, which tail current attenuates output oscillations of the voltage.
