Abstract:
1. An integrated circuit comprising: a shielding base element comprising a semiconductor substrate having a first dopant concentration; a semiconductor layer formed on a surface of the semiconductor substrate, the semiconductor layer having a second dopant concentration less than the first dopant concentration; a doping well formed in the semiconductor layer, the doping well having a third dopant concentration greater than the second dopant concentration; a shielding cover element formed in a strip-type arrangement, the strip-type arrangement comprising a plurality of spaced apart parallel strips, each strip extending from a first outer edge of the shielding cover element to a second outer edge of the shielding cover element; a circuit in the doping well; a shielding lateral element electrically coupling the base and cover elements and extending through the doping well and the semiconductor layer such that the circuit is contained within the shielding elements; and a rear side metallization contacting a surface of the shielding base element, the surface facing away from the circuit, wherein the shielding lateral element comprises at least one sinker contact formed in the semiconductor substrate, the semiconductor layer, and the doping well.
