Patent number: 7208392Abstract: A method of creating an electrically conducting bonding between a face of a first semiconductor element and a face of a second semiconductor element using heat treatment. The method applies the faces one against the other with the placing between them of at least one layer of a material configured to provide, after heat treatment, an electrically conducting bonding between the two faces. The deposited layers are chosen so that the heat treatment does not induce any reaction product between said material and the semi-conductor elements.

Publication number: 20030047289Abstract: A substrate holder is provided with two kinds of grooves (clearances) in the absorbing surface thereof. One kind of groove is made of a suitable depth so as to be able to quickly exhaust air and reduce pressure to thereby vacuum mount a substrate, and the other kind of groove is formed with a very small depth within such a range that there is no influence of dust being interposed between the holder and the substrate, in order to better the heat conduction between the substrate and the substrate holder. In addition, the area of the latter is made large as compared with the area of the former.Type: ApplicationFiled: September 17, 2002Publication date: March 13, 2003Inventors: Claude Jaussaud, Michel Bruel, Bernard Aspar

Patent number: 4241318Abstract: The laser comprises an amplifying medium placed between a first reflector and a second dispersive reflector, and a rotating wheel adapted to carry a plurality of optical deflector elements interposed between the amplifying medium and the second dispersive reflector.
