    摘要: A method for depositing metal layers, such as Ruthenium, on semiconductor substrates by a thermal chemical vapor deposition (TCVD) process includes introducing a metal carbonyl precursor in a deposition system, and depositing a metal layer from the metal carbonyl 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 the deposition system, the metal carbonyl is evaporated in a solid precursor evaporation system, and the precursor vapor is transported to the process chamber via a vapor delivery system. Further, an in-situ cleaning system is coupled to the vapor delivery system in order to perform periodic cleaning of the deposition system. Periodic in-situ cleaning permits achieving a greater deposition rate by operating the deposition system at higher temperature where precursor vapor can decompose and potentially deposit on surfaces of the deposition system.

    摘要: A method and a processing tool are provided for forming a metal layer with improved morphology on a substrate. The method includes pre-treating the substrate by exposing the substrate to excited species in a plasma, exposing the pre-treated substrate to a process gas containing a metal-carbonyl precursor, and forming a metal layer on the pre-treated substrate surface by a chemical vapor deposition process. The metal-carbonyl precursor can contain W(CO)6, Ni(CO)4, Mo(CO)6, CO2(CO)8, Rh4(CO)12, Re2(CO)10, Cr(CO)6, or Ru3(CO)12 or any combination thereof, and the metal layer can contain W, Ni, Mo, Co, Rh, Re, Cr, or Ru, or any combination thereof, respectively.

    摘要: A deposition member adapted for discharging a deposition material during a deposition process can acquire a coating during the deposition. Such an initial emissivity value is selected for the deposition member, before any of the coating became deposited, that the emissivity of the deposition member remains substantially unchanged during the deposition process. In a representative embodiment the deposition member is coated with an appropriate thin layer for achieving the selected emissivity value.
