  • Publication number: 20230271987
    Abstract: Some embodiments relate to precursors (including intermediate precursors) and related methods. To prepare an intermediate precursor, a mixture of bis (arene) metal complexes is combined with a first arene. The mixture of bis (arene) metal complexes and the first arene are heated and subsequently cooled. Upon cooling, a bis (first arene) metal complex precipitates from solution to obtain an intermediate precursor with high purity. To prepare a precursor, the bis (first arene) metal complex is contacted with a second arene and heated to obtain a precursor with high purity.

  • Publication number: 20230245894
    Abstract: Provided is a process comprising a selective ruthenium seed layer deposition with oxygen-free ruthenium precursors, followed by bulk deposition of metal-containing precursors such as tungsten, molybdenum, cobalt, ruthenium, and/or copper-containing precursors. The ruthenium seed layer deposition is highly selective for the conducting portions of the microelectronic device substrate while minimizing deposition onto the insulating surfaces of the microelectronic device substrate. In certain embodiments, the conducting portions of the substrate is chosen from titanium nitride, tungsten nitride, tantalum nitride, tungsten, cobalt, molybdenum, aluminum, and copper.
