    摘要: In one example of the invention, a method for depositing a tantalum-containing material on a substrate in a process chamber is provided which includes exposing the substrate to a tantalum precursor that contains TAIMATA and to at least one secondary precursor to deposit a tantalum-containing film during an atomic layer deposition (ALD) process. The ALD process is repeated until the tantalum-containing film is deposited with a predetermined thickness. Usually, the TAIMATA is preheated prior pulsing the tantalum precursor into the process chamber. A metal layer, such as tungsten or copper, may be deposited on the tantalum-containing material. The tantalum-containing material may include tantalum, tantalum nitride, tantalum silicon nitride, tantalum boron nitride, tantalum phosphorous nitride or tantalum oxynitride. The tantalum-containing material may be deposited as a barrier or adhesion layer within a via or as a gate electrode material within a source/drain device.

    摘要: A method and apparatus for selectively controlling deposition rate of conductive material during an electroplating process. Dopants are predominantly incorporated into a conductive seed layer on field regions of a substrate prior to filling openings in the field regions by electroplating. A substrate is positioned in one or more processing chambers, and barrier and conductive seed layers formed. A dopant precursor is provided to the chamber and ionized, with or without voltage bias. The dopant predominantly incorporates into the conductive seed layer on the field regions. Electrical conductivity of the conductive seed layer on the field regions is reduced relative to that of the conductive seed layer in the openings, resulting in low initial deposition rate of metal on the field regions during electroplating, and little or no void formation in the metal deposited in the openings.

    摘要: Embodiments of the invention provide processes to selectively form a cobalt layer on a copper surface over exposed dielectric surfaces. In one embodiment, a method for capping a copper surface on a substrate is provided which includes positioning a substrate within a processing chamber, wherein the substrate contains a contaminated copper surface and a dielectric surface, exposing the contaminated copper surface to a reducing agent while forming a copper surface during a pre-treatment process, exposing the substrate to a cobalt precursor gas to selectively form a cobalt capping layer over the copper surface while leaving exposed the dielectric surface during a vapor deposition process, and depositing a dielectric barrier layer over the cobalt capping layer and the dielectric surface. In another embodiment, a deposition-treatment cycle includes performing the vapor deposition process and subsequently a post-treatment process, which deposition-treatment cycle may be repeated to form multiple cobalt capping layers.
