Integrated circuit interconnect alloys having copper, silver or gold as the major constituent element. The resulting reduction in melting temperature allows for improved coverage of high aspect ratio features with reduced deposition pressure. The alloys are used to fabricate interconnects in integrated circuits, such as memory devices. The interconnects can be high aspect ratio features formed using a dual damascene process. The integrated circuits having the interconnects are applicable to semiconductor dies, devices, modules and systems.
