The diffusion furnace that could perform the oxidation process is composed of a furnace frame, a heater, a heating control device, a temperature measure device, a quartz furnace tube, a push-pull carrier tray, some gas path, and an exhaust gas treatment device. The temperature control requirements of this kind of diffusion furnaces are as follows:
Heating Temp Range | Ambient-1100℃ | Control Accuracy | ±2℃ |
Max Heating Rate | 15℃/min | Temp Uniformity | ±0.5℃/760mm |
Max Cooling Rate | 5℃/min | Stability | ±0.5℃/24h |
Â
The oxidation diffusion furnace generally uses thermocouples inside and outside the furnace to dynamic control the temperature. Each temperature zone is equipped with one inside and one outside thermocouple to ensure the reliability of the temperature control. S type semiconductor thermocouple(common practice utilizes multi-point thermocouple that has 3-9 different spots to grab temperature info) is often chosen to be the inside thermocouple which is used to sense the temperature of silicon wafer directly, and could translate to precise wafer temperature display.
