  • Patent number: 8946896
    Abstract: A dielectric layer overlies a semiconductor substrate. The substrate has components and appropriate contacts formed therein. The dielectric layer electrically insulates the substrate and components from overlying conductive interconnect layers. A barrier layer is arranged over the dielectric layer to isolate the interconnect layers from other structures. A copper layer is then deposited over the barrier layer and thick interconnect lines having a first width and a first height are realized. Then, the barrier layer is etched using one of many alternative techniques. The barrier layer has a second width and a second height wherein the second width of the barrier liner is selected to be greater than the first width of the thick copper interconnect.

  • Patent number: 8691646
    Abstract: A semiconductor device is formed having compatibility with FINFET process flow, while having a large enough junction area of to reduce the discharge ESD current density. Embodiments include forming a removable gate over an N? doped fin on a substrate, forming P+ doped SiGe or Si on an anode side of the fin, and forming N+ doped Si on a cathode side of the fin. The area efficiency of the semiconductor device layout is greatly improved, and, thereby, discharge of ESD current density is mitigated.
