Melanie Sachiko Yajima 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).

  • 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
