Anne-Marie Goncalves 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).

  • Mask for protecting a semiconductor material for localized etching applications
    Patent number: 11043390
    Abstract: The invention relates to the chemical etching of a semiconductor material, including: deposition at least one mask (PLP) on a first surface zone of a semiconductor material (SC); and chemically etching (S31) a second surface zone of the semiconductor material (SC) that is not covered by the mask (PLP). In particular, the aforementioned mask is produced in a material including polyphosphazene, which material protects the underlying semiconductor especially well.
    Type: Grant
    Filed: July 31, 2018
    Date of Patent: June 22, 2021
    Assignee: Centre National De La Recherche Scientifique

  • Method for chemically passivating a surface of a product made of a III-V semiconductor material and the product obtained by such a method
    Patent number: 9514961
    Abstract: A method for chemically passivating a surface of a product made of a III-V semiconductor material in which a) a P(N) polymer film is formed by deposition in a solvent comprising liquid ammonia. The film is formed by deposition, without electrochemical assistance, in the solvent, in the presence of an oxidizing chemical additive comprising phosphorous and generating electrical charge carriers in said surface.
