Create the energy-efficient technology to produce polycrystalline silicon

Since the beginning of Project No. 2/EEZLV02/14/AK/010/005 supervised by State Regional Development agency(VRAA) «Create the energy-efficient technology to produce polycrystalline silicon» a number of works have been conducted, which shall enable obtaining of silicon rods with parameters in accordance with requirements of power microelectronics in the process of ingot pulling with electron beam heating

– Additional evacuation units were mounted, which shall enable minimization of influence of vacuum volume of the heaters on vacuum volume containing pulled rod. Efficiency of different configurations of vacuum system was assessed. Revision and additions for this units have been made to allow their exploitation

– Development of the tools for preparation of polycrystalline silicon rods for analysis has started
