Abstract: PURPOSE: To raise precision of a temperature controller by measuring the film thickness of a thin-film of object which is to be thermally processed, measuring the film thickness of a thin film of object for a second thermal process device, and so adjusting the temperature controller that these film thickness is identical before the later process is repeated. CONSTITUTION: A wafer W is carried into a thermal process oven 1 for oxidation, and the thickness of oxide film thus obtained is measured with a film- thickness measuring part 8. The wafer W is set in a second thermal process device, and a temperature controller is set to the same temperature for oxidation, before a film thickness is measured. A difference between the film-thickness and that acquired in the previous process is acquired. Temperature difference = film thickness difference/film thickness temperature coefficient. If, for example, a film is thicker than that acquired in the previous process by 2.4 Å, a temperature difference is 2.4/1.2=2, so the temperature setting of a temperature controller 5 should be lowered by 2°. So, an oxidizing process with the second thermal process device is repeated until the thickness of the latter oxide film is equal to that acquired in the previous process.
