Title: Innovations of Sergey Vinogradov

Introduction

Sergey Vinogradov is a notable inventor based in Moscow, Russia. He has made significant contributions to the field of photodetector technology, holding two patents that showcase his innovative approach to semiconductor design.

Latest Patents

Vinogradov's latest patents include a method for manufacturing a photodetector with a bandwidth-tuned honeycomb cell photodiode structure. This photodetector is fabricated from a heavily doped semiconductor substrate. A plurality of adjoining cavities is formed in the substrate, which share cell walls. Each cavity contains a semiconductor well that is moderately doped with a second dopant, opposite in polarity to the first. An oxide layer is grown over the semiconductor wells, followed by an annealing process. Metal pillars are then formed, extending into each well with a central axis aligned with the optical path. The design allows for a decrease in capacitance between the electrodes as the number of semiconductor wells and the diameter of the metal pillars are reduced.
