  • Method for manufacturing an interconnect
    Patent number: 7541275
    Abstract: The present invention provides an interconnect for use in an integrated circuit, a method for manufacturing the interconnect, and a method for manufacturing an integrated circuit including the interconnect. The interconnect (100), among other elements, includes a surface conductive lead (160) located in an opening formed within a protective overcoat (110), and a barrier layer (140) located between the protective overcoat (110) and the surface conductive lead (160), a portion of the barrier layer (140) forming a skirt (145) that extends outside a footprint of the surface conductive lead (160).

  • Mechanically assisted restoring force support for micromachined membranes
    Patent number: 6657832
    Abstract: The present invention includes an integrated circuit switch including a membrane supported over a first conductor on a substrate, a conductive region on the membrane and connecting to the first conductor on the substrate, a pulldown electrode on the substrate and under the membrane and a pillar to support the membrane after the pulldown threshold has been reached. A voltage greater than a pulldown threshold is applied between the membrane and the pulldown electrode will pull the membrane down to make a capacitive coupling to the first conductor. The addition of the pillars increases the upward restoring force when the activation voltage is removed.
