Abstract:
1. A continuous processing system for forming stacked films by forming a first film on an object and then forming a second film, the continuous processing system comprising: a heating unit which heats an inside of a processing chamber accommodating a plurality of objects; a heat treatment condition storage unit which stores film-forming conditions of the first film and the second film, the film-forming conditions including a temperature in the processing chamber heated by the heating unit; a first model storage unit which stores a first model indicating a relationship between the temperature in the processing chamber and a film thickness of the first film to be formed; a second model storage unit which stores a second model indicating a relationship between the temperature in the processing chamber and a film thickness of the second film to be formed; a weight calculating unit which calculates weights of the first film and the second film, based on target film thicknesses of the first film and the second film; a stacked film model preparing unit which prepares a stacked film model indicating a relationship between the temperature in the processing chamber and a film thickness of the stacked films based on the weights calculated by the weight calculating unit, the first model stored in the first model storage unit, and the second model stored in the second model storage unit; a temperature calculating unit which calculates the temperature in the processing chamber for obtaining a desired film thickness of the stacked films, based on the stacked film model prepared by the stacked film model preparing unit; and an adjusting unit which adjusts the film thickness of the formed stacked films to be the desired film thickness by changing the temperature in the processing chamber stored in the heat treatment condition storage unit to the temperature calculated by the temperature calculating unit and forming the stacked films at the changed temperature.
