  • Patent number: 8796140
    Abstract: A method of providing signal, power and ground through a through-silicon-via (TSV), and an integrated circuit chip having a TSV that simultaneously provides signal, power and ground. In one embodiment, the method comprises forming a TSV through a semiconductor substrate, including forming a via in the substrate; and forming a multitude of conductive bars in the via. The multitude of conductive bars include at least one signal bar, at least one power bar, and at least one ground bar. The method further comprises connecting the at least one power bar to a power voltage source to apply power through the TSV; connecting the at least one ground bar to a ground voltage; and connecting the at least one signal bar to a source of an electronic signal to conduct the signal through the TSV and to form a hybrid power-ground-signal TSV in the substrate.

  • Publication number: 20120325541
    Abstract: A contact structure and assembly and a method for manufacturing the same for a microelectronics device includes first and second electrically conductive contacts being helically shaped. A carrier element is attached to and positioned between the first and second contacts. The first and second contacts are in electrical communication with each other, and the first and second contacts are in a mirror image relationship with each other. A pair of insulating substrates each include electrically conductive members. A contact point on each of the first and second contacts is attached and electrically communicating to respective electrically conductive members such that the first and second electrically conductive contacts between the pair of insulating substrates form an electrically conductive package. A metal layer on the carrier element provides electrical conductivity through a first opening defined by the carrier element between the first and second portions of the helix shaped contact.
