<p>Copper pyrazolate precursor compositions useful for the formation of copper in semiconductor integrated circuits, e.g., interconnect metallization in semiconductor device structures, as an adhesive seed layer for plating, for the deposition of a thin-film recording head and for circuitization of packaging components. The copper pyrazolate precursor compositions include fluorinated and non-fluorinated pyrozolate copper (I) complexes and their Lewis base adducts. Such precursors are usefully employed for liquid delivery chemical vapor deposition of copper or copper-containing material on a substrate.</p> |
