DSS™650 Crystalline Ingot Casting Furnace

GT Advanced Technologies is the industry’s leader in crystalline growth furnaces. The directional increased throughput of the DSS™650 improves productivity by 44 percent over prior generations. 

The DSS650 sets a new standard for cost-effective, crystalline ingot growth and helps customers achieve greater productivity and lower cost of ownership. The DSS650 produces significantly larger silicon ingots averaging 625 kg — resulting in up to 44 percent more output, while reducing consumable costs and optimizing the wafer slicing process.

GT Advanced Technologies is committed to delivering sustained value to customers. Customers who operate DSS450 and DSS450HP systems can easily upgrade their furnaces to take advantage of the improved throughput of the DSS650.

GT offers unmatched expertise in crystal growth processes, mechanical design, vacuum and high-pressure chambers, control system design, and crystal growth modeling.
