Burghausen, 24. Juni 2014 – SiTec GmbH today announced an innovative monosilane process technology that is expected to provide substantial energy savings compared to legacy processes. Marketed under the name “STARTM”, for a SiTec Applied Research product, the core innovation is applicable to both new and existing monosilane plants. STARTM starts with metallurgic silicon and produces electronic-grade quality monosilane for polysilicon production and VSLI (very large-scale integration) quality monosilane for sale. SiTec offers proven monosilane plant designs exceeding 10,000 MTA (metric tonnes per annum) capacities. STAR’s novel attributes significantly reduce both electrical and thermal energy requirement while debottlenecking the monosilane distillation train. New plants will experience best-in-class on-stream time and reduced costs, and up to 20% greater productivity from similarly sized equipment compared to traditional plant designs, and up to 10% to 15% lower cash cost depending on geographic-dependent energy pricing. SiTec’s patent-pending STARTM technology easily integrates into existing plants. Retrofitted plants will benefit by 20% greater capacity from existing redistribution and refining train equipment, reduced energy costs, and a 2 to 6 month payback period on retrofit investment. STAR’s unique drop-in technology enables uninterrupted production during the retrofit process. STARTM is designed to produce both VLSI and high electronic grade monosilane.
STAR’s energy’ envelope is not only superior to legacy processes but equals or betters reactive distillation designs without the attendant risk because STARTM uses proven technology.
“STARTM is a direct result of SiTec’s continuing commitment to applied research and development and to monosilane feedstock technology in particular,” says Dr. Josef Biedermann, Managing Director SiTec GmbH. “SiTec is dedicated to inventing and perfecting world-class polysilicon technologies tailored to industry needs at its hydrochlorination and monosilane research facility in Seattle, USA.”
“We are very excited about our proprietary STARTM process. We believe it brings tremendous value in use,” says Mark Dassel, Executive Vice President Polysilicon Technology. “STARTM greatly reduces energy consumption and is based on proven redistribution processes. SiTec is committed to bringing superior technologies to the world-wide polysilicon industry. STARTM is an important new addition to our company’s full-spectrum polysilicon technologies.”
The company will provide additional detail on its new monosilane process at the “Silicon for the Chemical and Solar Industry” conference to be held in Trondheim, Norway, June 23 – 26, 2014.
