 Kayex Automated Control System for Silicon Crystal Growing Furnaces
Consistent, Repeatable Growths
Reduced Labor Costs
The Kayex Automated Control System utilizes sophisticated measuring and control devices to enhance grower productivity by producing consistent, repeatable crystal growths. In addition, this control system also reduces labor costs by decreasing the amount of human operators needed to effectively run a crystal growing facility.
Programmed SOP Tables
- Parameters of crystal growth can be set to optimal specifications.
- Save programs for future crystal growths.
= Repeatability
= Flexibility
Heater Pyrometer
- Measures actual heater temperature instead of kW output - more reliable measurement because heater variations and aging are taken into account.
= Repeatability
Melt Pyrometer
- Measures silicon melt temperature.
- Once optimum melt temperature is determined, the control system calibrates that temperature as the starting point for future growths.
- Reduces possibility of operating technician error
= Repeatability
Dip Sensor System
- Machine senses moment when seed chuck touches silicon melt and begins growth process.
- Operating technician no longer needed for this task
= Reduced Labor Costs
Krystal Vision
- Monitors the diameter of the growing crystal.
- High update rate (measures per second) provides accurate data.
- If crystal diameter is not optimal, feedback loop causes seed lift speed and heater temperature to adjust simultaneously.
= Improved Response Time to Growth Variation
= Repeatability
