Title: Ulf Konig: Innovator in Photodetector Technology
Introduction
Ulf Konig is a notable inventor based in Ulm, Germany. He has made significant contributions to the field of photodetector technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and functionality of photodetectors, which are crucial in various applications.
Latest Patents
One of his latest patents is a SiGe photodetector with high efficiency. This innovative photodetector operates in two wavelength ranges and consists of two detectors arranged one on top of the other. Detector A is formed by a Si Schottky diode that absorbs light in the region of λ < 0.9 μm. Meanwhile, longer-waved light (1 μm < λ < 2 μm) is absorbed by detector B, which is made of an Si/SiGe pn-diode. To enhance efficiency, detector B incorporates an integrated resonator, and a Bragg reflector is mounted on the absorbing layer of detector B to further increase its performance.
Another significant patent involves a method of fabricating a heterobipolar transistor (HBT). This method utilizes differential epitaxy, allowing for a self-aligned fabrication of emitter and base contacts through an emitter mask and an exside-inside spacer structure. The emitter contact layer is composed of amorphous silicon. This process is temperature-stable and can be executed at lower implantation energies than conventional methods, enabling the production of high-quality HBTs suitable for mass production and capable of achieving high oscillation frequencies.
