Patent ID: 8188543

Claim:
An electronic device comprising: an SOI substrate including: a base material; a buried insulating layer overlying the base material; a semiconductor layer overlying the buried insulating layer, wherein the semiconductor layer is substantially monocrystalline; a doped region within the base material, wherein the doped region and the base material have a same conductivity type, and the doped region is at an elevation below and abuts the buried insulating layer; a first component lying within the semiconductor layer, wherein substantially all of the first component overlies the base material; a conductive structure extending through the semiconductor layer and the buried insulating layer, wherein: from a top view, the conductive structure has an inner perimeter, and the first component lies within the inner perimeter; the conductive structure abuts the doped region; and the conductive structure is electrically connected to the base material via the doped region; and an insulating spacer lying between the conductive structure and each of the semiconductor layer and the buried insulating layer.
