A method capable of perceiving a temperature difference between a susceptor surface and a wafer surface even without special complicated or high-priced equipment is needed. To accomplish such a purpose, the present invention provides a chemical vapor deposition device that comprises: a chamber; a susceptor which is positioned on the inner side of the chamber to allow rotation therein, wherein a wafer is stacked on an upper side; a gas supplier which is disposed on the inner side of the chamber, and sprays gas toward the wafer; a heater which is disposed on the inner side of the susceptor, and heats the wafer; a temperature sensor which is positioned in the chamber, and measures the temperature of the susceptor; a rotation recognition mark which is equipped at the position in which the mark is integrally rotated with the susceptor; a rotation recognition sensor which is positioned in the chamber in order to determine the rotated state of the susceptor, and detects the rotation recognition mark; and a controller which calculates the temperature distribution of the upper side of the susceptor by using the rotation recognition sensor and the temperature sensor, and controls the heater on the basis of the temperature distribution. |
