    摘要: Interconnect structures having alternating dielectric caps and an etchstop liner for semiconductor devices and methods for manufacturing such devices are described. According to an embodiment, an interconnect structure may include an interlayer dielectric (ILD) with a first hardmask layer over a top surface of the ILD. The interconnect structure may also include one or more first interconnect lines in the ILD. A first dielectric cap may be positioned above a top surface of each of the first interconnect lines. Additional embodiments include one or more second interconnect lines in the ILD that are arranged in an alternating pattern with the first interconnect lines. A second dielectric cap may be formed above a top surface of each of the second interconnect lines. Embodiments may also include an etchstop liner that is formed over top surfaces of the first dielectric caps.

    摘要: Embodiments of the invention include an interconnect structure and methods of forming such structures. In an embodiment, the interconnect structure may include an interlayer dielectric (ILD) with a first hardmask layer over a top surface of the ILD. Certain embodiments include one or more first interconnect lines in the ILD and a first dielectric cap positioned above each of the first interconnect lines. For example a surface of the first dielectric cap may contact a top surface of the first hardmask layer. Embodiments may also include one or more second interconnect lines in the ILD arranged in an alternating pattern with the first inter-connect lines. In an embodiment, a second dielectric cap is formed over a top surface of each of the second interconnect lines. For example, a surface of the second dielectric cap contacts a top surface of the first hardmask layer.
