Title: Method and apparatus of forming a sputtered doped seed layer
Inventor: NARASIMHAN MURALI
IPC: H01L21/28
Filed: 2000-09-27
Abstract: PURPOSE: A method and an apparatus for forming a sputtered doped seed layer are provided to reduce voids in the shape formed by depositing conductive material as well as decrease undesired oxidation effects on a substrate. CONSTITUTION: A dielectric layer(204) is deposited on the substrate(110) and etched to form the feature(200), such as a via, contact, trench or line. The term "substrate" is broadly defined as the underlying material and can include a series of underlying layers. The dielectric layer(204) can be a pre-metal dielectric layer deposited over a silicon wafer or an interlevel dielectric layer. A liner layer(206), such as a Ta layer, is deposited on the dielectric layer(204) as a transition layer to promote adhesion to the underlying material and reduce contact/via resistance. The liner layer(206) is preferably deposited using an IMP PVD process and can be deposited by other PVD processes, such as collimated or long throw sputtering or other methods such as CVD. Collimated sputtering is generally performed by placing a collimator(not shown) between the target and the substrate to filter sputtered material traveling obliquely through the collimator. Long throw sputtering is generally performed by increasing the spacing between the target and the substrate. The increased distance increases the probability that the sputtered material reaching the substrate is directed normal to the substrate surface. A barrier layer(208) of tantalum nitride(TaN) is deposited on the liner layer(206) using PVD, and preferably an IMP PVD process, especially for high aspect ratio features. The barrier layer prevents diffusion of copper into adjacent layers. While Ta/TaN are preferred, other liner and/or barrier layers that can be used are titanium(Ti), titanium nitride(TiN), tungsten(W), tungsten nitride(WN) and other refractory metals and their nitride counterparts.
