Abstract
A device includes a semiconductor substrate of a first conductivity type, wherein the semiconductor substrate comprises a first surface and a second surface opposite the first surface. A through-substrate via (TSV) extends from the first surface to the second surface of the semiconductor substrate. A well region of a second conductivity type opposite the first conductivity type encircles the TSV, and extends from the first surface to the second surface of the semiconductor substrate.
