  • Method for manufacturing a three dimensional power module
    Patent number: 10930572
    Abstract: A method for encapsulating an integrated circuit includes: forming first and second electrically insulating supports each having a planar surface, so as to form a recess in the first support with respect to its planar surface, and so as to form, with respect to the planar surface of each of the first and second supports, first and second reliefs, so that the first and second reliefs of the supports interact; forming a first electrical contact in the recess; positioning a chip in the recess; forming a second electrical contact on the second carrier; and superposing the first and second carriers so as to superpose their reliefs.
    Type: Grant

  • LAYOUT FOR ELECTRONIC COMPONENT TO BE COOLED, CHAMBER CONTAINING THE LAYOUT, VACUUM COOLING SYSTEM INCLUDING CHAMBER, METHOD OF USING THE VACUUM COOLING SYSTEM
    Publication number: 20130340991
    Abstract: The layout for an electronic component to be cooled during operation, said layout comprises a support (1) on which the electronic component (16) will be mounted, a base (2) configured so that it will be cooled, and a connecting element (3) mechanically and thermally connecting the base (2) to the support (1) so as to cool it. The connecting element (3) is configured such that the support (1) is free to move relative to the base (2), and the layout comprises a displacement adjustment system (4) configured so as to apply a movement to said support (1) relative to the base.

  • Radiation detection device having abutting detection elements and process for the production of said device
    Patent number: 5591959
    Abstract: The device includes at least two abutting detection elements (16, 18) having, on one face, a plurality of photodetectors (22, 24). A complementary detection element (26) has, on one face, a plurality of detectors (28) and is positioned astride the two abutting elements. The photodetectors of said complimentary element are positioned facing the faces of the two abutting elements and have no photodetector facing the photodetectors of the complementary element. The invention is useful in thermal imaging.
