Tesla Engineering Ltd Magnet Division



Superconducting Crystal Growth Magnets are used in the semi-conductor industry to improve the quality of monocrystalline silicon (mono-Si).  Mono-Si is the basic material used in the production of integrated circuits.

The application of a strong magnetic field during the growth of the larger diameter cylindrical ingots or boules of mono-Si reduces the incorporation of contaminants, thereby improving the quality of the resulting silicon crystal.

Tesla Engineering has developed and supplies a portfolio of next generation superconducting Crystal Grower Magnets for the growth of monocrystalline silicon using the Czochralski method (MCZ).

  • Magnets for crystal growing diameters of 200 - 450 mm
  • CUSP or TRANSVERSE with field strengths up to 4000 Gauss
  • Cryogen Free

  • <1 day downtime for cold head service
  • All magnets supplied with control unit to interface with customer pullers
  • Installation, commissioning and service available
  • Highly efficient cryogenic design for operation with only 2 cryocoolers


Tesla next generation superconducting magnets for silicon crystal growth.
