Abstract
Various embodiments include interconnect structures and methods of forming such structures. The interconnect structures can include a composite copper wire which includes at least two distinct copper sections. The uppermost copper section can have a thickness of approximately 1 micrometer or less, which inhibits surface roughening in that uppermost section, and helps to enhance cap adhesion with overlying layers.
