Abstract:
A semiconductor body that includes a plurality of field effect transistors in accordance with claim 1 whose gates are to be interconnected, and which are electrically isolated from one another by a surrounding trench that is filled with silicon oxide and in which a continuous conductive layer overlies the body and interconnects the gates of transistors, to be interconnected characterized in that:each transistor comprises a portion of the semiconductor body that is of a first conductivity type and source and drain regions of the opposite conductivity type, each of which has a portion that is on the surface of the semiconductive body and which are separated by a portion of the semiconductor body in which a channel is selectively formed during operation of the transistor, each said transistor further comprising a dielectric layer overlying the surface of the semiconductive body between the source and drain regions and suitable for serving as the gate dielectric, a conductor overlying the gate, and a buried layer that is of the first conductivity type and of higher concentration than that of the semiconductive body, and that is located essentially entirely between the source and drain regions displaced from the surface of the body and aligned with and opposite the gate.
