Photodetector arrangement having a semiconductor body with plural layers and transistors, measurement arrangement with a photodetector arrangement and process for operating a measurement arrangement

摘要

A photodetector arrangement has a semiconductor body formed of a substrate, a first layer at a first main surface of the semiconductor body, and a second layer at a second main surface of the semiconductor body. The second main surface is remote from the first main surface. A first and a second measurement terminal are arranged at the second main surface on the edge of the second layer in regions remote from one another and are formed for the electrical contact-connection of the second layer from outside the semiconductor body. A first and a second transistor couple the second layer to the first and respectively the second measurement terminal.
