Abstract: Interconnect structures and methods and apparatuses for forming the same are disclosed. In an embodiment, a method includes supplying a process gas to a process chamber; igniting the process gas into a plasma in the process chamber; reducing a pressure of the process chamber to less than 0.3 mTorr; and after reducing the pressure of the process chamber, depositing a conductive layer on a substrate in the process chamber.
