  • Publication number: 20160270237
    Abstract: Disclosed is a copper interconnection device including a surface-functionalized graphene capping layer and a method of fabricating the same, wherein electromigration of a fine copper interconnection can be suppressed by the capping layer having a thickness of ones of nm or less. Specifically, graphene is surface-functionalized to possess functional groups able to chemically interact with copper atoms and is thus used as the capping layer, whereby it is difficult to move the copper atoms through the chemical interaction with the functional groups by the use of only the capping layer as thin as ones of nm or less, effectively suppressing electromigration of the copper interconnection.

  • Patent number: 8916232
    Abstract: The embodiments fill the need of improving electromigration and reducing stress-induced voids of copper interconnect by enabling deposition of a thin and conformal barrier layer, and a copper layer in the copper interconnect. The adhesion between the barrier layer and the copper layer can be improved by making the barrier layer metal-rich prior copper deposition and by limiting the amount of oxygen the barrier layer is exposed prior to copper deposition. Alternatively, a functionalization layer can be deposited over the barrier layer to enable the copper layer being deposit in the copper interconnect with good adhesion between the barrier layer and the copper layer. An exemplary method of preparing a substrate surface of a substrate to deposit a functionalization layer over a metallic barrier layer of a copper interconnect to assist deposition of a copper layer in the copper interconnect in an integrated system in order to improve electromigration performance of the copper interconnect is provided.
