Services

• Manufacture of the single-crystal silicon in accordance with the technical specification requirements and taking the ordering customer’s requirements.
• Manufacture and sale of silicon of various makes, including high-resistance (ZKOF, KOF, KBO-1, KBO-2, KBO-4, KBO-6, BDM, KB-10, KB-12):
  • crystal-lattice orientation <111>, <100>;
  • concentration of the optically active oxygen up to 2,5∙10¹⁶ cm^-3 
• Manufacturing rate of the silicon producing shop floor makes 2,5 – 4,5 tons a year depending on the diameter of growing single-crystals.
• Production assets of the shop floor are TFZ-1435, FZ-1502, FZ-30 rigs.
