    Abstract: Embodiments of process chambers having a collimator are provided herein. In some embodiments, a process chamber includes: a chamber body having sidewalls and a top plate to define an interior volume therein, the top plate configured to support a target in the interior volume; a substrate support disposed in the interior volume opposite the top plate; a collimator disposed in the interior volume between the top plate and the substrate support; and a lower shield disposed in the interior volume about the collimator and coupled to the chamber body at a location below an upper surface of the collimator via a ceramic spacer disposed between the lower shield and the chamber body configured to electrically decouple the lower shield from the chamber body.

    Abstract: Embodiments disclosed herein generally relate to methods of depositing a plurality of layers. A doped copper seed layer is deposited in a plurality of feature definitions in a device structure. A first copper seed layer is deposited and then the first copper seed layer is doped to form a doped copper seed layer, or a doped copper seed layer is deposited directly. The doped copper seed layer leads to increased flowability, reducing poor step coverage, overhang, and voids in the copper layer.

    Abstract: A method of cleaning a surface of a substrate uses alcohol and water treatments. The method may include applying an alcohol treatment on a surface of the substrate with the alcohol treatment configured to provide surface reduction and applying a water treatment to the surface of the substrate with the water treatment configured to enhance selectivity of at least a portion of the surface for a subsequent barrier layer process by removing alcohol from the at least a portion of the surface. The water treatment may be performed simultaneously with the alcohol treatment or performed after the alcohol treatment. The water treatment may include vaporized water or water injected into a plasma to produce hydrogen or oxygen radicals.

    Abstract: Methods and apparatus for filling features on a substrate are provided herein. In some embodiments, a method of filling features on a substrate includes: depositing a first metallic material on the substrate and within a feature disposed in the substrate in a first process chamber via a chemical vapor deposition (CVD) process at a first temperature; depositing a second metallic material on the first metallic material in a second process chamber at a second temperature and at a first bias power to form a seed layer of the second metallic material; etching the seed layer in the second process chamber at a second bias power greater than the first bias power to form an intermix layer within the feature comprising the first metallic material and the second metallic material; and heating the substrate to a third temperature greater than the second temperature, causing a reflow of the second metallic material.
