Disclosed is a method for film formation, characterized by comprising allowing a treatment gas stream containing a metal carbonyl-containing treatment gas and a carbon monoxide-containing carrier gas to flow into a region on the upper outside of the outer periphery of a substrate to be treated in a diameter direction of the substrate while avoiding the surface of the substrate and diffusing the metal carbonyl from the treatment gas stream into the surface of the substrate to form a metal film on the surface of the substrate.

Physical vapor deposition is augmented by chemical vapor deposition from one or more organometallic compounds to deposit multi-component materials. The organometallic compounds may be carbonyls. The process may be used to deposit coatings and repair material on superalloy turbine engine parts.
摘要:
A method of forming a metal film using a metal carbonyl compound as a material is disclosed that includes the steps of: (a) introducing a reactive gas into a space near a surface of a substrate to be processed; and (b) introducing a gaseous phase material including the metal carbonyl compound into the space on the surface of the substrate to be processed, and depositing the metal film on the surface of the substrate to be processed after step (a). Step (a) is executed in such a manner as to prevent substantial deposition of the metal film on the substrate to be processed.
摘要:
A multi-step method for depositing ruthenium thin films having high conductivity and superior adherence to the substrate is described. The method includes the deposition of a ruthenium nucleation layer followed by the deposition of a highly conductive ruthenium upper layer. Both layers are deposited using chemical vapor deposition (CVD) employing low deposition rates.
