  • Patent number: 7977243
    Abstract: A Cl2 gas plasma is generated at a site within a chamber between a substrate and a metal member. The metal member is etched with the Cl2 gas plasma to form a precursor. A nitrogen gas is excited in a manner isolated from the chamber accommodating the substrate. A metal nitride is formed upon reaction between excited nitrogen and the precursor, and formed as a film on the substrate. After film formation of the metal nitride, a metal component of the precursor is formed as a film on the metal nitride on the substrate. In this manner, a barrier metal film with excellent burial properties and a very small thickness is produced at a high speed, with diffusion of metal being suppressed and adhesion to the metal being improved.

  • Patent number: 7923374
    Abstract: In a metal film production apparatus, a copper plate member is etched with a Cl2 gas plasma within a chamber to form a precursor comprising a Cu component and a Cl2 gas; and the temperatures of the copper plate member and a substrate and a difference between their temperatures are controlled as predetermined, to deposit the Cu component of the precursor on the substrate, thereby forming a film of Cu. In this apparatus, Cl* is formed in an excitation chamber of a passage communicating with the interior of the chamber to flow a Cl2 gas, and the Cl* is supplied into the chamber to withdraw a Cl2 gas from the precursor adsorbed onto the substrate, thereby promoting a Cu film formation reaction. The apparatus has a high film formation speed, can use an inexpensive starting material, and can minimize impurities remaining in the film.
