  • Patent number: 7696062
    Abstract: A method for mounting a dielectric substrate to a semiconductor substrate, such as mounting a dielectric antenna substrate to an MMIC semiconductor substrate. The method includes providing a thin dielectric antenna substrate having metallized layers on opposing sides. In one embodiment, carrier wafers are used to handle and maintain the dielectric substrate in a flat configuration as the metallized layers are patterned. The dielectric substrate is sealed to the semiconductor substrate using a low temperature bonding process. In an alternate embodiment, the metallized layers on the dielectric substrate are patterned simultaneously so as to prevent the substrate from curling.
    Type: Grant
    Filed: July 25, 2007
    Date of Patent: April 13, 2010
    Assignee: Northrop Grumman Systems Corporation

  • Patent number: 6629872
    Abstract: The invention provides a method for manufacturing a pet model, commonly referred to as a pet mannequin, here a dog mannequin, is implanted on a soft walled hollow molded dog body formed of a polyvinyl chloride molding solution, the soft walled hollow molded dog body including a torso, trunk and leg portions, the molded body and a head portion and a pair of ears are molded separately. The molded body and head portions are filled with a chaff packing. Precut lengths of hair-simulating wool yarn are implanted into the wall of the molded body using a crochet needle. Thereafter, the chaff packing is removed from the implanted body and head portions.
