Abstract:
1. A metal organic chemical vapor deposition device, comprising: a chamber; susceptors rotatably installed within the chamber and configured to have at least one substrate seated therein; a plurality of heaters configured to heat the susceptors and to have their temperatures independently controlled; gas sprayers placed over the susceptors and configured to spray group III gas and group V gas toward the susceptors; a plurality of temperature detection sensors placed on one side of the susceptors and configured to measure temperatures of heating regions heated by the respective heaters; and a controller configured to control the temperatures of the heating regions considering detected temperature values, detected by the respective temperature detection sensors; wherein the temperature controller comprises individual controllers for controlling the respective heating regions and stores a temperature setting value for one of the heating regions as a representative temperature setting value; wherein the temperature controller controls a temperature of a representative heating region, selected from among the heating regions, based on the representative temperature setting value and controls the temperatures of the remaining heating regions other than the representative heating region based on the detected temperature value detected by a temperature detection sensor for detecting the temperature of the representative heating region, from among the temperature detection sensors; and wherein the temperature controller measures a temperature ramping tendency detected at the representative heating region and performs control so that the remaining heating regions other than the representative heating region comply with the temperature ramping tendency of the representative heating region.
