Abstract
Provided is a method in which a difference between a surface temperature of a susceptor and a surface temperature of a substrate is accurately grasped without using a complicated high-priced equipment. A temperature control method for a chemical vapor deposition apparatus includes detecting a rotation state of a susceptor on which a substrate is accumulated on a top surface thereof, measuring a temperature of the top surface of the susceptor, calculating a temperature distribution of the top surface of the susceptor, based on the detected rotation state and the measured temperature, and controlling the temperature of the top surface of the susceptor, based on the calculated temperature distribution.
