Abstract: The invention provides for an alternative and less complex method of manufacturing a bipolar transistor comprising a field plate (17) in a trench (7) adjacent to a collector region (21), which field plate (17) employs a reduced surface field (Resurf) effect. The Resurf effect reshapes the electric field distribution in the collector region (21) such that for the same collector-base breakdown voltage the doping concentration of the collector region (21) can effectively be increased resulting in a reduced collector resistance and hence an increased bipolar transistor speed. The method comprises a step of forming a base window (6) in a first base layer (4) thereby exposing a top surface of the collector region (21) and a part of an isolation region (3). The trench (7) is formed by removing the exposed part of the isolation region (3), after which isolation layers (9,10) are formed on the surface of the trench (7).
