    摘要: The present invention discloses an interconnection structure for providing electrical communication with an electronic device which includes a body that is formed substantially of copper and a seed layer of either a copper alloy or a metal that does not contain copper sandwiched between the copper conductor body and the electronic device for improving the electromigration resistance, the adhesion property and other surface properties of the interconnection structure. The present invention also discloses methods for forming an interconnection structure for providing electrical connections to an electronic device by first depositing a seed layer of copper alloy or other metal that does not contain copper on an electronic device, and then forming a copper conductor body on the seed layer intimately bonding to the layer such that electromigration resistance, adhesion and other surface properties of the interconnection structure are improved.

    摘要: An interconnect structure for an integrated circuit (IC) device includes an elongated, electrically conductive line comprising one or more segments formed at a first width, w1, and one or more segments formed at one or more additional widths, w2 . . . wN, with the first width being narrower than each of the one or more additional widths; wherein the relationship of the total length, L1, of the one or more conductive segments formed at the first width to the total lengths, L2 . . . LN, of the one or more conductive segments formed at the one or more additional widths is selected such that, for a given magnitude of current carried by the conductive line, a critical length with respect to an electromigration short-length effect benefit is maintained such that a total length of the conductive line, L=L1+L2+ . . . +LN, meets a minimum desired design length regardless of the critical length.
