Abstract:
Circuits, structures and techniques for independently connecting a surrounding material in a part of a semiconductor device to a contact of its respective device. To achieve this, a combination of one or more conductive wells that are electrically isolated in at least one bias polarity are provided.

Claim (Index 1):
A transistor device comprising:\n a substrate; at least one buffer layer comprising a compound semiconductor material; a device layer including a current conducting region formed over the at least one buffer layer; a source contact and a drain contact formed on a top surface of the device layer; and a conductive well formed in the substrate and disposed underneath both the source and drain contacts, wherein the conductive well is electrically isolated in at least one bias polarity from the substrate, such that a potential under the source contact and the drain contact is independent from a potential of the substrate; and a conductive via extending from the top surface of the device layer through the device layer and through the buffer layer to penetrate and terminate within the conductive well, electrically connecting the source contact to the conductive well; wherein the substrate has a backside opposite a side adjacent the buffer layer and the drain contact is independent in potential from the backside of the substrate; and wherein the conductive well has a doping of opposite polarity to the substrate.
