| 摘要 |
A method of manufacturing a semiconductor device is disclosed. The manufacturing method comprises heating a reactor, setting a semiconductor wafer in the reactor, supplying a reactive gas into the reactor to form a film on the semiconductor wafer or on an inner surface of the reactor, and measuring a temperature change outside the reactor and a temperature change inside the reactor to determine a thickness of the film on the semiconductor wafer or on the inner surface of the reactor on the basis of a relationship between a ratio of the temperature changes and a thickness of the film.
