    摘要: The present invention provides methods of forming cobalt layers on a structure comprising forming a preliminary cobalt layer on a semiconductor substrate by introducing an organic metal precursor onto the semiconductor substrate and treating a surface of the preliminary cobalt layer under an atmosphere of a hydrogen-containing gas to remove impurities contained in the preliminary cobalt layer. Compositions of cobalt layers are also provided. Further provided are semiconductor devices comprising cobalt layers provided herein.
