<p>A plasma processing device includes a processing chamber defining a plasma processing space and a stage for mounting thereon a target substrate in the processing chamber. The plasma processing device further includes a gas supply mechanism for introducing a processing gas into the plasma processing space, a plasma generation mechanism for supplying electromagnetic energy into the plasma processing space, and a control unit configured to, if a command to start a plasma process for the target substrate mounted on a substrate carry-in stage is issued, perform a warm-up process for supplying the processing gas into the plasma processing space by the gas supply mechanism and supplying the electromagnetic energy by the plasma generation mechanism in a state where no target substrate is mounted on the stage.</p> |
