Abstract
In an element of an integrated circuit including a transistor and a 'majority carrier diode' at least one terminal of which is connected to the base or collector of said transistor, the 'majority carrier diode' is laid out in a transistor portion of the integrated circuit to be surrounded by a part of base region extended to the surface of the semiconductor body, so that the paths for the load current of the transistor and the diode current are separated from each other, whereby a high speed operation at a heavy load current is made possible and/or so that reliability of said majority carrier diode is increased.
