Patent ID: 7709950

Claim:
A semiconductor device comprising: a semiconductor substrate having first and second main surfaces opposite to each other; at least one trench extending from the first main surface to a first depth position in the semiconductor substrate, the at least one trench defining a perimeter boundary around a portion of the semiconductor substrate; at least one conductive via extending from the first main surface through the semiconductor substrate to the second main surface, the at least one conductive via being formed from the portion of the semiconductor substrate bounded by the at least one trench forming a perimeter boundary thereof; a dielectric lining surrounding the at least one conductive via through the semiconductor substrate, the at least one conductive via being electrically isolated from the semiconductor substrate by the dielectric lining; an electrical component electrically connected to the at least one conductive via at the first main surface; and a cap sealed to the first main surface, the cap enclosing at least a portion of the electrical component and the electrical connection between the electrical component and the at least one conductive via.
