Patent ID: 7790626

Claim:
A film deposition method comprising: mounting, using a preparation process, a target object on a mounting table in a vacuum processing container, the target object having a top surface and a recess opened at the top surface; and depositing, using a film deposition process, a metal film on a sidewall of the recess by generating metal ions by making a metal target sputter with a plasma generated from a discharge gas in the processing container and by applying, to the mounting table, a bias power to cause a metal film deposition based on a metal ion attraction and a sputter etching based on the plasma generated from the discharge gas simultaneously on the top surface of the target object, wherein the bias power in the film deposition process is set to a level at which a rate of depositing the metal film by attracting the metal ions is substantially balanced with an etching rate of the sputter etching based on the plasma generated from the discharge to cause a film deposition amount on the top surface of the target object to become substantially zero.
