Patent JP-S5681931-A (JP)
Title: Oxidizing furnace for semiconductor substrate
Inventor: KASHIHARA TOMIO
IPC: H01L21/31
Filed: 1979-12-10
Abstract: PURPOSE:To control a heater input by a method wherein a thermoelectric couple indicating a temperature lowering as that of a substrate is arranged near the substrate and the signal is processed through proportional integral differential (PID) processing for the set temperature, and the set value is corrected by changing-over a resistance in accordance with the temperature difference to the substrate and then, the corrected value is processed through the PID processing for a heater temperature. CONSTITUTION:When a thermoelectric couple 15d is equipped in a stainless pipe having an approximately 1mm. thickness, is inserted into a quartz glass tube having an approximately 1mm. thickness and arranged close to an Si substrate, the substrate temperature A and the thermoelectric couple temperature B increase gradually as a lot proceeds. According to an SiO2 film thickness, it drops by DELTAT1 in the same way. The difference between the detection temperature T4 of the thermoelectric couple 15d and the set value is operated through PID and the result is added to set values T1-T3 of each heater. Whereas, since the temperature of the substrate drops at each lot as DELTAT11, DELTAT12... an equivalent quantity to DELTATIN is previously set at a resistance ratio R0/(R0+R1), R0/(R0+R2)... and it is changed-over every time to be added to the corrected signal and it is operated through a PID operation with DELTAT1-T3 to control heaters 14c-14d. With this constitution, a temperature control of high accuracy can be performed and a yield is improved.
