Abstract
For depositing a metallic film, the following steps are repeatedly conducted: a step in which a precoat film is formed on the inside of a chamber; a step in which two or more substrates to be treated are subjected to the deposition of a metallic film thereon by introducing each substrate into the precoated chamber, placing the substrate on the stage, feeding a treating gas while heating the substrate to generate a plasma of the treating gas, and depositing a metallic film on the substrate by plasma CVD; and a step in which after the film deposition on the substrates has been completed, a cleaning gas is introduced into the chamber to conduct dry cleaning. In the step in which two or more substrates to be treated are subjected to the deposition of a metallic film thereon, a conductive film is formed on the stage one or more times in the course of the step.
