A vertically integrated hybrid component is implemented in the form of a wafer level package including: at least two element substrates assembled one above the other; a molded upper sealing layer made of an electrically insulating casting; and an external electrical contacting of the component being implemented on the top side via at least one contact stamp which is embedded in the sealing layer so that (i) its lower end is connected to a wiring level of an element substrate and (ii) its upper end is exposed in the surface of the sealing layer.

Component in the form of a wafer level package and method for manufacturing same

In an ASIC element, vias are integrated into the CMOS processing of an ASIC substrate. The ASIC element includes an active front side in which the circuit functions are implemented. The at least one via is intended to establish an electrical connection between the active front side and the rear side of the element. The front side of the via is defined by at least one front-side trench which is completely filled, and the rear side is defined by at least one rear-side trench which is not completely filled. The rear-side trench opens into the filled front-side trench.

A sensor includes at least one micro-patterned diode pixel that has a diode implemented in, on, or under a diaphragm, and the diaphragm in turn being implemented above a cavity. The diode is contacted via supply leads that are implemented at least in part in, on, or under the diaphragm, and the diode is implemented in a polycrystalline semiconductor layer. The diode is implemented by way of two low-doped diode regions or at least one low-doped diode region. At least parts of the supply leads are implemented by way of highly doped supply lead regions of the shared polycrystalline semiconductor layer.

Sensor and method for the manufacture thereof

A MOSFET component used to switch high currents includes a current path that is parallel-connected to the base-emitter link of the parasitic bipolar transistor, extracts the minority charge carriers, and prevents the parasitic transistor from being biased into conduction.

Drift-free avalanche breakdown diode

An integrated circuit having a gate oxide, preferably for a DMOS circuit having a protective device against electrostatic overvoltages (ESD), is to connect a limiting circuit in series with the protective device. This series circuit means that, during the wafer production, an increased voltage can be applied to the gate of the integrated circuit, for testing the gate oxide, without the circuit being limited to a lower value. After testing, the limiting circuit is connected irreversibly in its low-resistance state, with the result that subsequent ESD interference voltages are limited by the built-in protective device. A zener zapping diode is provided as the limiting circuit. An advantageous result of the arrangement is the fact that an additional bonding connection for connecting the gate connection to the protective device is no longer necessary.
