Light-sensitive structure for semiconductor personal identity number (PIN) diodes operates as photodiode structure to convert optical/light signals into electrical signals.

摘要

A personal identity number (PIN) diode (2) converts light signals into electrical signals. A semiconductor diode has feed lines (4,5)/metallized layers to contact doped zones and to make a link with another later circuit e.g. an electric amplifier. To use a passive interface circuit for an active broadband interface between the semiconductor diode and the later circuit, the feed line has an interface circuit (10) and forms a coplanar/micro-strip line on a partial length (L).
