The main field of application of our detectors is the measurement of X-rays in high energy physics, astrophysics or material analysis.
To be able to fulfill this objective with high quantum efficiency detectors are needed with a large sensitive thickness - in optimum case using the full extension of the silicon starting material. Using high ohmic material the silicon can be fully depleted over this distance with moderate voltages especially if a double side process is used - with the electronics on one side and the radiation entrance window on the other side. Moreover by this scheme a homogenous radiation entrance window is achieved either optimized for a thin dead layer or for the implementation of antireflecting coating layers.
Optimum spectroscopic results require a good signal to noise ratio. As leakage current and noise is highly correlated our detectors are fabricated in an ultrapure process with cleanest materials in a clean room area of class 1-10.
We appreciate very much to find and to be able to use the technology and the equipment necessary for the fabrication of the detectors at the Semiconductor Laboratory of the Max-Planck-Institutes of Physics and Extraterrestrical Physics in Munich, Neuperlach.
