Abstract:
1. A semiconductor device comprising a thermally and electrically conductive bottom plate on an upper side of which there is a semiconductor element with a first connection region and a second connection region, said regions being coupled to, respectively a first conductor and a second conductor, said semiconductor element being surrounded by an electrically insulating synthetic resin envelope that covers a side face of the bottom plate, which side face is provided with a recess that is filled with a part of the envelope, characterized in that the recess, viewed in cross-section at right angles to an edge of the bottom plate, takes the form of a staircase with at least two steps, wherein a connection region of a drain of the semiconductor element borders on the bottom plate and forms a drain connection that projects from the envelope, and wherein connection regions of a source and a gate of the semiconductor element are situated on a side of the semiconductor element opposite the connection region of the drain, and the first and second conductors form, respectively, source and gate connections that project from the envelope.
