Abstract: For the integration of an npn bipolar transistor with a hetero bipolar transistor, a placeholder layer is generated in a base region of the hetero bipolar transistor after structuring a collector structure for both types of transistors, wherein the placeholder layer is not present in a base region of the bipolar transistor. After generating the base of the bipolar transistor, the base of the bipolar transistor is covered, whereupon the placeholder layer is removed and the base of the hetero bipolar transistor is generated in the places where the placeholder layer has been removed. The emitter structure is again generated equally for both types of transistors so that an integrated circuit results which includes bipolar transistors and hetero bipolar transistors whose collector structures and/or whose emitter structures consist of identical production layers. Thus, space-saving and cost-effective integrated circuits may be produced benefiting from the advantages of both types of transistors.
