Patents by Inventor Marine Rouillon-Martin

Marine Rouillon-Martin 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).

  • Integrated circuit having a laser connection of a conductor to a doped region of the integrated circuit
    Patent number: 5528072
    Abstract: The conductor 15 to be connected to the doped region 12 of the substrate 11 has an edge 15a at which the laser beam 20 is aimed, regulated such as to definitively create a zone of low electrical resistance 19 in the dielectric layer 13 that separates the conductor from the doped region. The invention is particularly applicable to programming by laser of read only memories and defective integrated circuits with a view to correcting them.
    Type: Grant
    Filed: August 10, 1994
    Date of Patent: June 18, 1996
    Assignee: Bull, S.A.
    Inventors: Alain Boudou, Marie-Francoise Bonnal, Marine Rouillon-Martin
