    Abstract: PURPOSE: To estimate an accurate temperature for a heat treatment equipment by estimating the temperature of a substance to be treated in order to perform the heat treatment of the substance. CONSTITUTION: A reactive pipe 2 is provided with heaters 31-35, temperature sensors Sin1-Sin5 and Sout1-Sout5 and houses a wafer boat 23. A control part 100 estimates the temperatures of wafers W of five zones corresponding to the heaters 31-35 of the pipe 2 and also the temperatures of sensors Sin1-Sin5 by means of the electric power of the sensors Sin1-Sin5, Sout1-Sout5 and the heaters 31-35. The functions f1-f5 showing the relation between the estimated temperature and actual temperature of every zone are calculated from the relation of estimated and actual temperatures among sensors Sin1-Sin5. The estimated wafer temperatures are substituted for the functions f1-f5 for correcting the wafer temperatures. The electric power supplied to the heaters 31-35 are individually controlled so that the corrected wafer temperatures are converged on a target temperature track.
