    Abstract: An IC chip and design structure having a TWV contact contacting the TWV and extending through a second dielectric layer over the TWV. An IC chip may include a substrate; a through wafer via (TWV) extending through at least one first dielectric layer and into the substrate; a TWV contact contacting the TWV and extending through a second dielectric layer over the TWV; and a first metal wiring layer over the second dielectric layer, the first metal wiring layer contacting the TWV contact.

    Abstract: Methods of forming through wafer vias (TWVs) and standard contacts in two separate processes to prevent copper first metal layer puddling and shorts are presented. In one embodiment, a method may include forming a TWV into a substrate and a first dielectric layer over the substrate; forming a second dielectric layer over the substrate and the TWV; forming, through the second dielectric layer, at least one contact to the TWV and at least one contact to other structures over the substrate; and forming a first metal wiring layer over the second dielectric layer, the first metal wiring layer contacting at least one of the contacts.

    Abstract: Method of forming wires in integrated circuits. The methods include forming a wire in a first dielectric layer on a substrate; forming a dielectric barrier layer over the wire and the first dielectric layer; forming a second dielectric layer over the barrier layer; forming one or more patterned photoresist layers over the second dielectric layer; performing a reactive ion etch to etch a trench through the second dielectric layer and not through the barrier layer; performing a second reactive ion etch to extend the trench through the barrier layer; and after performing the second reaction ion etch, removing the one or more patterned photoresist layers, a last formed patterned photoresist layer removed using a reducing plasma or a non-oxidizing plasma. The methods include forming wires by similar methods to a metal-insulator-metal capacitor.
