Patent ID: 7718926

Claim:
A film deposition apparatus comprising: a reactor into which a substrate is transported and process gas is introduced, a substrate supporting part for holding the substrate and rotating it at a desired rpm, a heater disposed above the substrate and divided into a plurality of zones, each zone of the heater including a lamp, for heating the substrate and forming a film on the substrate, a thermometer for measuring substrate temperatures on a plurality of measurement points in a radial direction of the substrate, a lamp power supply for adjusting a lamp power outputted to the lamp in each zone of the heater, a temperature controller for separately setting a lamp power in each zone of the heater based on the substrate temperature which is measured by the thermometer, and for outputting the lamp power to the lamp power supply to control a surface temperature of the substrate, a pressure gauge for measuring a pressure in the reactor, and a monitoring device which has a process model of a thickness profile of the substrate, for inputting to a prediction equation of the process model, the lamp power in each zone of the heater from the lamp power supply or the lamp power and the pressure measured in the reactor by the pressure gauge during thermal processing of the substrate, for predicting the thickness profile, and for deciding whether an abnormality occurs in the thermal processing of the substrate based on the predicted thickness profile, the process model including functions of the lamp power in each zone of the heater or the lamp power and the pressure in the reactor.
