Various embodiments of the present disclosure are directed towards an integrated chip. The integrated chip includes a semiconductor substrate having a device substrate overlying a handle substrate and an insulator layer disposed between the device substrate and the handle substrate. A gate electrode overlies the device substrate between a drain region and a source region. A conductive via extends through the device substrate and the insulator layer to contact the handle substrate. A first isolation structure is disposed within the device substrate and comprises a first isolation segment disposed laterally between the gate electrode and the conductive via. A contact region is disposed within the device substrate between the first isolation segment and the conductive via. A conductive gate electrode directly overlies the first isolation segment and is electrically coupled to the contact region.
