7. The rapid thermal processing apparatus according to claim 1 wherein the control part controls the irradiation intensity of the first lamp part in response to a difference between the calculated temperature of the substrate and a predetermined setting temperature, and controls the irradiation intensity of the second lamp part in response to a difference between the calculated temperature of the substrate support part and the predetermined setting temperature.
This application is a Divisional of prior application Ser. No. 11/032,087 filed on Jan. 11, 2005, now U.S. Pat. No. 7,283,734 the contents being incorporated herein by reference.
The emissivity computing part 13 computes the emissivity of the back surface of the semiconductor substrate 1 by the monitoring of the output signals from the emissivity sensor 61 a′ and the radiation light sensor 61 a.
The temperature computing part 9 carries out the monitoring of the output signal from each radiation light sensor of the radiation light sensor group 61, and computes the temperature of the semiconductor substrate 1 based on both the emissivity of the back surface of the semiconductor substrate 1 which is computed by the emissivity computing part 13 and the radiation light from the back surface of the semiconductor substrate 1 which is received by each radiation light sensor.
After the step S214 is performed, the control is returned to the step S212. That is, monitoring the temperature of the semiconductor substrate by the radiation light sensors 61 e and 61 d on real time, according to the known PID control, feedback control to the lamp power for heating is performed, and it heats to the target temperature (Tset) of the request of the substrate circumference part and the substrate support part by the lamp group 51 e and 51 d.
After the step S224 is performed, the control is returned to the step S222. That is, monitoring the temperature of the semiconductor substrate by the radiation light sensors 61 e and 61 d on real time, according to the known PID control, feedback control to the lamp power for heating is performed, and it heats to the target temperature (Tset) of the request of the substrate circumference part and the substrate support part by using the lamp group 51 e and 51 d.
After the step S243 is performed, the control is returned to the step S241. That is, monitoring the temperature of the semiconductor substrate by the radiation light sensors 61 e and 61 d on real time, according to the known PID control, the feedback control to the lamp power for heating is performed and the substrate circumference part and the substrate support part 3 are heated to the desired target temperature (Tset) by the lamp group 51 e and 51 d.
