Abstract:
1. A semiconductor device comprising: a semiconductor body; a field of transistor cells integrated in the semiconductor body, a plurality of the transistor cells forming a power transistor and at least one of the transistor cells forming a sense transistor, wherein the plurality of the transistor cells forming the power transistor are connected in parallel; a first source electrode arranged on the semiconductor body electrically connected to the transistor cell(s) of the sense transistor but electrically isolated from the plurality of the transistor cells forming the power transistor; and a second source electrode arranged on the semiconductor body and covering the transistor cells of both the power transistor and the sense transistor, and at least partially covering the first source electrode in such a manner that the second source electrode is electrically connected only to the plurality of the transistor cells forming the power transistor but electrically isolated from the transistor cell(s) of the sense transistor.
