Zusammenfassung:A vapor deposition system and its wafer and thin-film temperature control method are disclosed. A susceptor carries a plurality of satellite disks with each bearing a wafer. The susceptor makes revolution around a center axle and each satellite disk rotates around its own axis. A carrier gas approaches a first surface of the wafer and is heated to form a thin film to be deposited on the first surface. A heating plate is placed at a second surface of the wafer and the second surface is opposite to the first surface. One or more remote temperature detectors measure a temperature of a surface of the heating plate and the surface is opposite to the wafer. And a wafer-side temperature is calculated by the measured temperature of the heating plate.
