摘要： A new method of etching metal lines with reduced microloading effect is described. Semiconductor device structures are provided in and on a semiconductor substrate and covered with an insulating layer. A barrier metal layer is deposited overlying the insulating layer and a metal layer is deposited overlying the barrier metal layer. The metal layer is covered with a photoresist mask wherein there are both wide spaces and narrow spaces between portions of the photoresist mask. The metal layer is etched away where it is not covered by the photoresist mask wherein the barrier metal layer is reached within the wide spaces while some of the metal layer remains within the narrow spaces. The metal layer remaining within the narrow spaces is selectively etched away. Thereafter, the barrier metal layer not covered by the photoresist mask is etched away wherein the insulating layer is reached within the wide spaces while some of the barrier metal layer remains within the narrow spaces. The barrier metal layer remaining within the narrow spaces is selectively etched away. Thereafter, the insulating layer not covered by the photoresist mask is overetched to complete the metal lines without microloading in the fabrication of an integrated circuit.

摘要： A new method of depositing a copper layer, using disproportionation of Cu(I) ions from a solution stabilized by a polar organic solvent, for single and dual damascene interconnects in the manufacture of an integrated circuit device has been achieved. A dielectric layer, which may comprise a stack of dielectric material, is provided overlying a semiconductor substrate. The dielectric layer is patterned to form vias and trenches for planned dual damascene interconnects. A barrier layer is deposited overlying the dielectric layer to line the vias and trenches. A simple Cu(I) ion solution, stabilized by a polar organic solvent, is coated overlying said barrier layer. Water is added to the stabilized simple Cu(I) ion solution to cause disproportionation of the simple Cu(I) ion from the Cu(I) ion solution. A copper layer is deposited overlying the barrier layer. The copper layer may comprise a thin seed layer for use in subsequent electroplating or electroless plating of copper or may comprise a thick copper layer to fill the vias and trenches. The integrated circuit is completed.

摘要： A technique for operating a network involves controlling the black-holing of traffic by selectively redirecting unicast traffic destined for a dual-homed customer equipment (CE) device from a first provider backbone bridge (PBB) provider edge (PE) device to a second PBB PE device in response to a service failure. Unicast traffic is selectively redirected from the first PBB PE device to the second PBB PE device for a time interval that is long enough to enable the customer source MAC address (CMAC)-to-backbone MAC address (BMAC) association of the second PBB PE device to be learned by other PBB PE devices.

摘要： A technique for operating a network involves controlling the black-holing of traffic by forcing customer source MAC address (CMAC)-to-backbone source MAC address (BMAC) associations at provider backbone bridge (PBB) provider edge (PE) devices to be flushed from their corresponding forwarding information bases (FIBs) in response to a service failure so that new CMAC-to-BMAC associations, which are reflective of a secondary traffic path, are learned faster than they would otherwise be learned if the network had relied on native functionality to learn new CMAC-to-BMAC associations that are reflective of the secondary traffic path.

摘要： Providing redundancy between an active component and a standby component in a network router comprises maintaining a first route input information base associated with the active component, synchronizing with the first route information base a second route input information base associated with the standby component, generating a route output information base using the second route input information base, and comparing the generated route output information base, in the event of switchover of the standby component to an active mode, to a synchronized route output information base associated with the standby component which synchronized route output information base reflects routes known to have been shared with one or more peers by the active component prior to the switchover, and sharing and/or withdrawing routes as necessary to reflect any differences between the generated route output information base and the synchronized route output information base.
