    摘要: A semiconductor component includes a semiconductor body having an edge with an edge zone of a first conductivity type. Charge compensation regions of a second conductivity type are embedded into the edge zone, with the charge compensation regions extending from a top side of the semiconductor component vertically into the semiconductor body. For the number Ns of charge carriers present in a volume Vs between two charge compensation regions that are adjacent in a direction perpendicular to the edge, and for the number Np of charge carriers present in a volume Vp between two charge compensation regions that are adjacent in a direction parallel to the edge, Np>Ns holds true.

    摘要: A lateral MISFET having a semiconductor body has a doped semiconductor substrate of a first conduction type and an epitaxial layer of a second conduction type, which is complementary to the first conduction type, the epitaxial layer being provided on the semiconductor substrate. This MISFET has, on the top side of the semiconductor body, a drain, a source, and a gate electrode with gate insulator. A semiconductor zone of the first conduction type is embedded in the epitaxial layer in a manner adjoining the gate insulator, a drift zone of the second conduction type being arranged between the semiconductor zone and the drain electrode in the epitaxial layer. The drift zone has pillar-type regions which are arranged in rows and columns and whose boundary layers have a metal layer which in each case forms a Schottky contact with the material of the drift zone.

    摘要: A power semiconductor component (1) contains a weakly doped drift zone (9), a drain zone (10) and a MOS structure (12) situated at the front side (2) of the power semiconductor component (1). An edge plate (6) of the first conductivity type is provided at its edge (8) above the drift zone (9). The edge plate (6) is doped more highly than the drift zone (9). Situated above the edge plate (6) is an insulation layer (24) with an overlying field plate (7) made of polysilicon. The field plate (7) forms together with the edge plate (6) a plate capacitor structure which increases the drain-source output capacitance of the power semiconductor component (1), so that fewer radiofrequency interference disturbances are caused by the power semiconductor component (1) during switching.

    摘要: An IGBT with monolithic integrated antiparallel diode has one or more emitter short regions forming the diode cathode in the region of the high-voltage edge. The p-type emitter regions of the IGBT have no emitter shorts. The counterelectrode of the diode exclusively comprises p-type semiconductor wells on the front side of the device. Particularly in applications, such as lamp ballast, in which the diode of the IGBT is firstly forward-biased, hard commutation is not effected and the current reversal takes place relatively slowly. The emitter short regions may be strips or points below the high-voltage edge. The horizontal bulk resistance is increased and the snapback effect is reduced without reducing the robustness in the edge region. In a second embodiment, the IGBT is produced using thin wafer technology and the thickness of the substrate defining the inner zone is less than 200 μm. The thickness of the emitter region or of the emitter regions and short region(s) is less than 1 μm. A transparent emitter is preferable in this case.

    摘要: 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.
