摘要:
A film formation method is disclosed for depositing a metal film on a target substrate by supplying a metal carbonyl source in gas phase to a surface of the target substrate and decomposing the source near the surface of the target substrate. The method includes a step of preferentially decomposing the metal carbonyl source in an area near the outer peripheral portion of the target substrate when the metal film is being deposited on the surface of the target substrate. As a result, a CO concentration in the atmosphere is increased locally near the outer peripheral portion of the target substrate and the depositing of the metal film on the outer peripheral portion is better controlled.

Provided is a placing table structure which is disposed in a processing container and has a subject to be processed thereon so as to form a thin film on the subject in the processing container by using raw material gas which generates thermal decomposition reaction having reversibility. The placing table structure is provided with a placing table for placing the subject to be processed on a placing surface, i.e., an upper surface of the placing table structure, and a decomposition restraint gas supply means which is arranged in the placing table for the purpose of supplying decomposition restraint gas, which restraints thermal decomposition of the raw material gas, toward a peripheral section of the subject placed on the placing surface of the placing table.

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.

A semiconductor device, which suppresses formation of an organic impurity layer and has excellent adhesiveness to a copper film and a metal to be a base, is manufactured. A substrate (wafer W) coated with a barrier metal layer (base film) 13 formed of a metal having a high oxidation tendency, such as titanium, is placed in a processing chamber. At the time of starting to supply water vapor or after that, a material gas containing an organic compound of copper (for instance, Cu(hfac)TMVS) is supplied, and a copper film is formed on the surface of the barrier metal layer 13 whereupon the oxide layer 13a is formed by the water vapor. Then, heat treatment is performed on the wafer W, and the oxide layer 13a is converted into an alloy layer 13b of a metal and copper which constitute the barrier metal layer 13.

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.
