    摘要: Precursor compositions useful for atomic layer deposition (ALD) and chemical vapor deposition (CVD) of strontium ruthenium oxide (SrRuO3) thin films, e.g., in the manufacture of microelectronic devices, as well as processes of making and using such precursors, and precursor supply systems containing such precursor compositions in packaged form. Cyclopentadienyl compounds of varied type are described, including cyclopentadienyl as well as non cyclopentadienyl ligands coordinated to ruthenium, strontium or barium central atoms. The precursors of the invention are useful for forming contacts for microelectronic memory device structures, and in a specific aspect for selectively coating copper metallization without deposition on associated dielectric, under deposition conditions in a forming gas ambient.
