Title: The Innovations of Sebastien Jouan
Introduction
Sebastien Jouan is a notable inventor based in Crolles, France. He has made significant contributions to the field of photonics, particularly in the development of high quantum efficiency photodiodes. With a total of 4 patents to his name, Jouan's work has advanced the technology used in various optical applications.
Latest Patents
One of his latest patents is for a photodiode of high quantum efficiency. This invention includes at least one central pad arranged on a light-receiving surface of a photodiode semiconductor substrate. The pad is made of a first material and features lateral sidewalls surrounded by a spacer made of a second material, which has a different optical index than the first material. The lateral dimensions of the pad are smaller than the operating wavelength of the photodiode, and both materials are transparent to that wavelength. The pads and spacers are formed simultaneously with the gate electrodes and sidewall spacers of MOS transistors.
Another significant patent is for a SPAD-type photodiode with a semiconductor substrate that has a light-receiving surface. This invention features a lattice formed of interlaced strips made of a first material covering the light-receiving surface. The lattice includes openings with lateral walls covered by a spacer made of a second material, which also has a different optical index. The pitch of the lattice is on the order of the operating wavelength of the photodiode, and both materials are transparent at that wavelength. The lattice is made of a conductive material that is electrically coupled to an electrical connection node.
