Abstract

There is provided a technique that includes (a) acquiring temperature data of at least one of a heater temperature defined by a temperature of a heater and a furnace temperature defined by an inner temperature of a process chamber, and acquiring a power supply value indicating an electric power supplied to the heater; (b) acquiring a reference temperature of the temperature data; (c) creating a predetermined equation using a prediction model of estimating a predicted temperature of the temperature data; (d) calculating a solution of minimizing a deviation between the reference temperature and the predicted temperature based on the predetermined equation; and (e) outputting a calculated power supply value calculated from the solution, and processing a substrate while controlling heating of the heater based on the calculated power supply value.
