Patent ID: 7527827

Claim:
A method for performing a predetermined process on a substrate having a coating film formed thereon in a substrate processing apparatus having a control section, the method comprising: controlling a temperature of a disposing plate on which the substrate is disposed; supplying a process gas including an ammonia gas containing a water vapor into a chamber housing the disposing plate; preparing a data base denoting a relationship between each of parameters and a processing time of the predetermined process and storing the data base in the control section, the parameters including the temperature of the disposing plate, a supply rate of the ammonia gas, and an amount of the water vapor contained in the ammonia gas; inputting a preset specific time value of the process time into the control section; calculating candidate values of the parameters with reference to the data base by the control section, so as for the candidate values to finish the predetermined process by the specific time value; determining specific values of the parameters to be used, based on the candidate values; and setting the parameters to be the specific values and performing the predetermined process for the specific time value under control of the control section.
