Patent ID: 6921436

Claim:
A substrate processing apparatus for processing a substrate which has a coated film, comprising: a disposing plate on which the substrate is disposed; a plate temperature control mechanism for controlling a temperature of the disposing plate; a chamber for housing the disposing plate; a gas supply mechanism for supplying a process gas consisting of an ammonia gas containing a water vapor into the chamber; an input section for inputting a processing time of the substrate with the process gas; a data base in which data denoting a relationship between each of a plurality of parameters and the processing time, the plurality of parameters consisting of 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, is stored; and a control mechanism for determining, on the basis of the data stored in the data base, the temperature of the disposing plate, the supply rate of the ammonia gas, and the amount of the water vapor contained in the ammonia corresponding to the processing time inputted into the input section.
