摘要: A monolithically integrated circuit arrangement is arranged in a disc-shaped monocrystalline semiconductor body (100) of a first conductivity type, which semiconductor body consists of silicon and has a first and second main surface. The monolithically integrated circuit arrangement contains a vertical MOSFET power transistor (T1) which consists of a plurality of partial transistors connected in parallel and surrounded by a guard ring (4) of a second conductivity type opposite that of the semiconductor body (100). Proceeding from the first main surface (13), at least one zone (7, 8) of the conductivity type of the semiconductor body (100) but of increased impurity concentration is diffused into the guard ring (4) so as to form at least one active and/or passive peripheral circuit element (T2) which has a protective and/or regulating and/or control function.
