Abstract
In an embodiment, a semiconductor device includes a semiconductor substrate having a front surface, a LDMOS transistor arranged in the front surface of the substrate and having an intrinsic source, and a through substrate via. A first conductive layer lines sidewalls of the through substrate via and extends from the through substrate via onto the front surface of the semiconductor substrate and is electrically coupled with the intrinsic source.
