    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 raw material recovery method for recovering a raw material of an organic metallic compound, which has the property of being stable toward a specific refrigerant without being decomposed thereby, from exhaust gas discharged from a treatment container in which a metallic thin film is formed on the surface of an object to be treated by using source gas obtained by vaporizing the raw material is characterized by being provided with a solidification step for solidifying the unreacted source gas by cooling the exhaust gas by bringing the exhaust gas into contact with the refrigerant and reprecipitating the raw material, and a recovery step for separating and recovering the raw material reprecipitated in the solidification step from the refrigerant. To provide a method for controlling an exhaust gas flow rate so that flow of gas in a processing chamber becomes uniform.
