Claim Text:
1. A substrate processing apparatus, comprising: a process chamber configured to accommodate a substrate having a metal film as a metal wiring polished on a first insulating film having a plurality of wiring grooves, and having a second insulating film polished on the metal film; a process gas supply part configured to supply a process gas to the substrate; an activation part configured to activate the process gas; a receiving part configured to receive a film thickness distribution data on the polished second insulating film; a computation part configured to compute processing data for adjusting a film thickness distribution of a stacked insulating film formed of the second insulating film after being polished and a third insulating film, by adjusting a film thickness distribution of the third insulating film to be formed on the second insulating film after being polished, based on the film thickness distribution data; and a control part configured to control the process gas supply part and the activation part to adjust the film thickness distribution of the stacked insulating film by activating the process gas to form the third insulating film, based on the processing data, such that a concentration of active species of the process gas generated in a central side of the substrate and a concentration of active species of the process gas generated in a peripheral side of the substrate are different.
