Abstract

A substrate processing apparatus may include a process chamber configured to accommodate a substrate having a metal film polished on a first insulating film and 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 computation part configured to compute processing data for adjusting a film thickness distribution of a stacked insulating film having the polished second insulating film and a third insulating film by adjusting a film thickness distribution of the third insulating film based on the film thickness distribution data of the polished second insulating film; 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 based on the processing data.
