Title: The Innovations of Sébastien Cortial

Introduction

Sébastien Cortial is a notable inventor based in Sassenage, France. He has made significant contributions to the field of infrared imaging technology, holding a total of four patents. His work focuses on enhancing the performance and efficiency of infrared detectors.

Latest Patents

Cortial's latest patents include a low thermal capacity micro-bolometer and an associated manufacturing method. This innovative infrared imaging micro-bolometer integrates a membrane that is suspended on a substrate by support arms. The membrane is designed with an absorbing material that captures infrared radiations and a thermometric material that transduces these captured radiations. Notably, the thermometric material occupies a surface area smaller than 0.4 times that of the membrane. Additionally, the membrane features at least one central dielectric layer positioned between the absorbing material and the thermometric material. Recesses are strategically formed in both the absorbing material and the dielectric layer in areas of the membrane that lack the thermometric material.

Another significant patent involves a process for producing an infrared detector. This method includes hybrid bonding a detection chip to a second chip, achieved through the adhesion of contacts and insulator layers from both chips. The process also entails the removal of a substrate from the detection chip to access a deep oxide layer, forming conductive pads that connect to transistors in a semiconductor layer. Finally, microbolometers are created, suspended over the deep oxide layer and electrically linked to the conductive pads.
