    摘要: A method of sputtering a copper seed layer and the target used therewith. The copper included in the sputtering target includes a first dopant reactive with copper and a second dopant unreactive with copper. Examples of the first dopant include Ti, Mg, and Al. Examples of the second dopant include Pd, Sn, In, Ir, and Ag. The amount of the first dopant may be determined by testing stress migration and that of the second dopant by testing electromigration.

    摘要: The invention is a precleaning process suitable for fabricating metal plugs in a low-&kgr;, carbon-containing dielectric. More specifically, the invention is a process for cleaning a contact area of a metal conductor on a semiconductor workpiece so as to minimize damage to a low-&kgr;, carbon-containing dielectric overlying the metal. After forming contact openings in the low-&kgr; dielectric so as to expose contact areas on the underlying metal conductor, the contact areas are cleaned by exposing the workpiece to an atmosphere formed by plasma decomposition of a mixture of hydrogen-containing and helium gases. Surprisingly, our preclean process can repair damage to the dielectric caused by preceding process steps, such as oxygen plasma ashing processes for removing photoresist.
