Patent ID: 7999358

Claim:
An integrated circuit comprising: a shielding base element comprising a semiconductor material; a shielding cover element; a circuit in a carrier substrate of the integrated circuit; and a shielding lateral element electrically coupling the base and cover elements such that the shielding base element, the shielding cover element and the shielding lateral element form a Faraday cage, wherein the circuit is contained within the Faraday cage, wherein the carrier substrate has an SOI substrate with a semiconductor substrate, at the surface of which is formed an insulating layer, at the surface of which is situated a semiconductor layer with the circuit formed in its surface, wherein the shielding base element is part of the SOI substrate and separated from the circuit by the insulating layer, wherein the shielding lateral element comprises at least one sinker contact trench formed in the carrier substrate through the insulating layer and the semiconductor layer, and wherein the sinker contact trench and the shielding base element provide a lower portion of the Faraday cage and wherein the shielding cover element provides an upper portion of the Faraday cage.
