Didier Gourier has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for manufacturing a sensor chip for the direct conversion of X-rays, a sensor for the direct conversion of X-rays and the dental radiology apparatus for using such a sensor
    Patent number: 10937921
    Abstract: This invention relates to a method to manufacture a chip to detect the direct conversion of X-rays. It also relates to a direct conversion detector for X-rays using such a chip and dental radiology equipment using at least one such detector. The method to manufacture the wafer comprises a step for applying pressure (3, 4, 4 a) to a powdered polycrystalline semiconductor material and a step for heating (5-9) during a set time period. It comprises a preliminary step for providing an impurity level of at least 0.2% in the polycrystalline semiconductor material.
    Type: Grant
