  • Publication number: 20080122078
    Abstract: An integrated circuit apparatus comprises a semiconductor substrate having a plurality of devices formed thereon, one or more metallization layers to interconnect the plurality of devices, and a bond pad formed over the one or more metallization layers and electrically coupled to at least one of the metallization layers. A first passivation layer is formed over the bond pad and over the metallization layers and a redistribution interconnect formed on the passivation layer. A first via formed through the first passivation layer electrically couples the redistribution interconnect to the bond pad. A second passivation layer is formed on the redistribution interconnect to prevent thermomechanical degradation and improve electromigration performance. A dielectric layer is formed on the second passivation layer and a die-side bump is formed on the dielectric layer.

  • Publication number: 20070262451
    Abstract: A transistor gate comprises a substrate having a pair of spacers disposed on a surface, a high-k dielectric conformally deposited on the substrate between the spacers, a recessed workfunction metal conformally deposited on the high-k dielectric and along a portion of the spacer sidewalls, a second workfunction metal conformally deposited on the recessed workfunction metal, and an electrode metal deposited on the second workfunction metal. The transistor gate may be formed by conformally depositing the high-k dielectric into a trench between the spacers on the substrate, conformally depositing a workfunction metal atop the high-k dielectric, depositing a sacrificial mask atop the workfunction metal, etching a portion of the sacrificial mask to expose a portion of the workfunction metal, and etching the exposed portion of the workfunction metal to form the recessed workfunction metal. The second workfunction metal and the electrode metal may be deposited atop the recessed workfunction metal.
