Abstract
Embodiments of semiconductor devices and driver circuits include a semiconductor substrate having a first conductivity type, an isolation structure (including a sinker region and a buried layer), an active device within a portion of the substrate contained by the isolation structure, and a resistor circuit. The buried layer is positioned below the top substrate surface, and has a second conductivity type. The sinker region extends between the top substrate surface and the buried layer, and has the second conductivity type. The active device includes a body region, which is separated from the isolation structure by a portion of the semiconductor substrate having the first conductivity type. The resistor circuit is connected between the isolation structure and the body region. The resistor circuit may include one or more resistor networks and, optionally, a Schottky diode and/or one or more PN diode(s) in series and/or parallel with the resistor network(s).
