    摘要: The present invention provides a method for improving the adhesion of copper and other metal-comprising conductive metals to a barrier layer. A barrier layer is provided that has a first surface that is substantially unoxidized, wherein at least a portion of the first surface is free from the presence of oxygen atoms. A conductive layer is then deposited onto the first surface of the barrier layer. The substantially unoxidized state of the first surface enhances the adhesion of the metal-comprising layer to the barrier layer. The method is particularly useful in obtaining excellent adhesion of a copper nucleation layer to an underlying barrier layer surface.

    摘要: An apparatus and method for sputter depositing a magnetic film on a substrate to produce a magnetic device such as magnetic recording heads for reading digital information from a storage medium. The apparatus of the invention includes a sputtering chamber containing a target and a substrate, and a magnet array disposed within the chamber to form a substantially parallel magnetic field at a surface of the substrate. The sputtering chamber reduces interference between the magnetron and the magnet array by providing a long throw distance and/or a grounded collimator. The magnet array is preferably a circular ring.
