    摘要: A method for depositing metal layers on semiconductor substrates by a thermal chemical vapor deposition (TCVD) process includes introducing a process gas containing a metal carbonyl precursor in a process chamber and depositing a metal layer on a substrate. The TCVD process utilizes a short residence time for the gaseous species in the processing zone above the substrate to form a low-resistivity metal layer. In one embodiment of the invention, the metal carbonyl precursor can be selected from at least one of W(CO)6, Ni(CO)4, Mo(CO)6, Co2(CO)8, Rh4(CO)12, Re2(CO)10, Cr(CO)6, and Ru3(CO)12 precursors. In another embodiment of the invention, a method is provided for depositing low-resistivity W layers at substrate temperatures below about 500° C., by utilizing a residence time less than about 120 msec.

    摘要: A metal CVD process includes a step (A) of introducing a gaseous source material containing a metal carbonyl compound into a process space adjacent to a surface of a substrate to be processed in such a manner that the metal carbonyl compound has a first partial pressure, and a step (B) of depositing a metal film on the surface of the substrate by introducing a gaseous source material containing the metal carbonyl compound into the process space in such a mater that the metal carbonyl compound has a second, smaller partial pressure. The step (A) is conducted such that there is caused no substantial deposition of the metal film on the substrate.
