ABSTRACT:
A method of processing a signal of a thermal flow-rate sensor, provides a temperature monitor for monitoring a temperature at a representative point on a substrate support member; obtains the temperature at the representative point corresponding to the flow rate by use of the temperature monitor; and corrects an output of the sensor in accordance with a value corresponding to the temperature as well as a value corresponding to the temperature at the representative point when the flow rate is in a steady state.
