A process for producing monolithically integrated multifunction circuit arrangements. A substrate having an integrated circuit formed therein is provided, and further multilayer semiconductor components and the corresponding electrical leads are arranged on top of one another on the substrate surface. The multilayer semiconductor components and the electrical leads are produced from an epitaxially grown semiconductor layer sequence.

Process of producing monolithically integrated multifunction circuit

The invention relates to a semiconductor body, which is composed of at least one semiconductor device, especially one impatt-diode, with integrated heat sink. The series of semiconductor layers, out of which the semiconductor device is produced, is made up of one first p.sup.+ -doped semiconductor layer, which has the function of an etching stop layer, of a contact layer and a buffer layer at the same time.
