Patent ID: 7361936

Claim:
An optical transmitting and/or receiving device, comprising: a semiconductor component including a first contact for obtaining a reference voltage and a second contact for obtaining or providing a high-frequency electrical signal; an electrically conducting carrier substrate having a first surface and a second surface; said semiconductor component configured on said first surface of said carrier substrate; said second surface of said carrier substrate having a metallization for obtaining said reference voltage; said first surface of said carrier substrate having a first contacting region; said carrier substrate having an electrical path for conducting said reference voltage through said carrier substrate to said first contacting region of said first surface of said carrier substrate; said first contact of said semiconductor component being electrically connected to said first contacting region of said first surface of said carrier substrate; wherein said carrier substrate includes a highly conducting, highly-doped semiconductor substrate and an adjoining high-impedance, low-doped epitaxial layer; said second surface of said carrier substrate facing away from said epitaxial layer; said epitaxial layer having a surface facing away from said semiconductor substrate; said surface of said epitaxial layer facing away from said semiconductor substrate forming said first surface of said carrier substrate; said electrical path through said carrier substrate having an electrically highly conducting connecting region extending through said epitaxial layer; and said electrically conducting connecting region connected to said first contacting region.
