Abstract
An MPS diode and a manufacturing method is provided. The diode includes a semiconductor body including an active area and an adjacent termination area, the active area includes a drift region of a first conductivity type, and a plurality of wells of a second type different from the first conductivity type, the wells being mutually spaced apart, each well forming a respective PN-junction with the drift region. The diode further includes a metal layer assembly arranged on a surface of the semiconductor body and at least one metal layer, the metal layer assembly forming a plurality of Schottky contacts together with the drift region and a plurality of respective Ohmic contacts with the wells. The drift region includes a doped region surrounding each of the wells and having a higher dopant concentration than a remainder of the drift region, and the doped region is spaced apart from the termination area.
