JD-1200 Mono-Crystal Furnace is a flexible shaft lifting-pulling type mono-crystal furnace. It is a device used in the inert gas atmosphere using the graphite resistance heater to melt certain silicon materials for growing dislocation- free mono crystals by the Czochralski method. It can produce high-quality silicon mono-crystal required by large-scaled integrated circuits. This equipment can use maximum 28inch hot-zone system with charging of maximum 370KG to grow mono-crystals of 10inch or less. Its production capacity has increased 20% compared with the JD-1100 Mono-Crystal Furnace as a result of increased charging. It is the sister model of JD-1100 Mono-Crystal Furnace. Besides having the characteristics of the JD-1100 Mono-Crystal Furnace, it has greatly improved in design, convenient maintenance, automaticity and other performance standards.
