Trichlorosilane supply for Polysilicon plants

DEI provides proprietary Process Definition Packages and Basic Engineering Design as well as start-up assistance, training and optimization consulting for the manufacture of Trichlorosilane (TCS.)

The overall process involves reacting a metallurgical grade of silicon with hydrogen chloride to produce trichlorosilane and hydrogen:

Si + 3 HCl -> HSiCl3 + H2 and other by products

With DEI's proprietary process, a high yield of solar or semiconductor grade TCS is produced.

Integration of a TCS plant with a silicon deposition plant and DEI's proprietary methods for converting by-products provides better utilization of raw materials, minimization of waste streams, and lower energy consumption per Kg of polysilcon produced. Let DEI give you a competitive advantage.

DEI has signed agreements on TCS with over 40 companies on 4 continents. Contact DEI for a confidentiality agreement to get more details.
