  • Publication number: 20040046225
    Abstract: For signal transmission between the high-pressure side (2) and the low-pressure side (3) of a semiconductor power component (1), with a reduced surface field (RESURF) region (4) disposed between the high-pressure side (2) and the low-pressure side (3), it is proposed that at least one polysilicon resistor (5) be provided, which is disposed above the RESURF region (4) and is electrically insulated from it, as a result of which a high off-state voltage resistance is assured.

  • Publication number: 20040021203
    Abstract: A semiconductor power component and a method for producing a semiconductor power component, in particular a vertical NPT-IGBT for ignition applications with a breakdown voltage of less than approx. 1000 V. The semiconductor power component includes a wafer substrate of a first conductive type including a rear-side emitter region of a second conductive type and a front-side drift region of the first conductive type; a rear-side anode contact which is connected to the emitter region and extends partially to the front-side surface; a front-side MOS control structure; and a front-side cathode contact which is connected to a front-side source region and a body region of the front-side MOS control structure. The thickness of the drift region is much larger than the width of the space charge region at a defined breakdown voltage; and the thickness of the rear-side emitter region is greater than 5 &mgr;m.

  • Patent number: 6684866
    Abstract: An ignition system is for an internal combustion engine having an ignition device that requires a high voltage (ignition voltage) for igniting the ignition spark. Two ignition coils are provided, which have secondary windings that are each connected to electrodes of a spark plug, which have primary windings that may be connected in each case by a switching arrangement to a supply voltage source, and a drive circuit, via which the ignition coils are driven in a time-displaced manner.

  • Patent number: 6674125
    Abstract: A semiconductor power component is described having a rear-side anode contact, a rear-side emitter region of a first conductivity type, which is connected to the rear-side anode contact, a drift region, which is connected to the rear-side emitter region and partially extends to the front-side surface, a front-side MOS control structure, and a front-side cathode contact, which is connected to the source region and the body region. The drift region includes a first drift region of the second conductivity type, a second drift region of the second conductivity type, and a third drift region of the first conductivity type. The first drift region is a buried region. The second drift region connects the front-side surface to the first drift region. The third drift region borders on a body region and connects the front side surface to the first drift region.

  • Patent number: 6661056
    Abstract: The present invention relates to a circuit configuration for protecting against polarity reversal of a DMOS transistor. A charge carrier zone (30) is provided, situated in the drift zone (14) of DMOS transistor (10), made up of individual partial charge carrier zones (32) situated at a distance from one another and connected to one another in a conducting manner, the charge carrier zone (30) having an opposite charge carrier doping from that of the drift zone (14), and being able to be acted upon by a potential that is negative with respect to a potential present at a drain terminal (24) of the DMOS transistor (10), so that a short-circuit current is prevented.

  • Patent number: 6236068
    Abstract: A transistor component and a method of producing the transistor component having at least one insulated-gate electrode and with lateral and vertical current flow. The transistor component is used for low-loss switching of high currents and is optionally designed in bipolar or MOS technology. The component includes a rear contact connected to a substrate across a highly doped region, where the highly doped region has a concentration profile of the dopant atoms that tapers out smoothly into the interior of the component. The highly doped region can be produced by a diffusion process.
