摘要:
In the back end of an integrated circuit employing dual-damascene interconnects, the interconnect members have a first non-conformal liner that has a thicker portion at the top of the trench level of the interconnect; and a conformal second liner that combines with the first liner to block diffusion of the metal fill material.
