A structure includes a laterally diffused (LD) MOSFET with an n-type drift region disposed on a surface of a substrate and a p-type body region contained in the drift region. The structure further includes an n-type source region contained in the p-type body region; an n-type drain region contained in the n-type drift region; a gate electrode disposed on a gate dielectric overlying a portion of the p-type body region and the n-type drift region and an electrically conductive field shield member disposed within the n-type drift region at least partially beneath the p-type body region and generally parallel to the gate electrode. The electrically conductive buried field shield member is contained within and surrounded by a layer of buried field shield oxide and is common to both a first LD MOSFET and a second LD MOSFET that are connected in parallel. Methods to fabricate the structure are also disclosed.
