Patent ID: 7524687

Claim:
A method for producing an integrated semiconductor component comprising a first semiconductor layer construction for emitting radiation and a second semiconductor layer construction for receiving radiation, comprising: (a) providing a substrate; (b) epitaxially depositing a first semiconductor layer sequence, which contains a radiation-generating region, onto the substrate and a second semiconductor layer sequence, which contains a radiation-absorbing region, onto the first semiconductor layer sequence; (c) patterning the second semiconductor layer sequence, or both semiconductor layer sequences, in order to uncover at least one first location for electrical contact-connection on that surface of the first semiconductor layer sequence which is remote from the substrate, and at least one second location for electrical contact-connection on that surface of the second semiconductor layer sequence which is remote from the substrate; (d) electrically insulating the first semiconductor layer construction, which has the first semiconductor layer sequence and is arranged between the substrate and the first location for contact-connection, from the second semiconductor layer construction, which has the first and the second semiconductor layer sequence and is arranged between the substrate and the second location for contact-connection; and (e) applying of a first contact layer to the free surface of the substrate and a second contact layer at least to the first and second locations for contact-connection.
