Abstract

A monocrystal 16 (Fig. 2, not shown) is pulled from a melt in an inductively heated crucible 12 provided with a tapering projection 13 having a groove 14, pulling being completed after the lowest point in the surface of the melt is below the top of the projection. The crystal 16 is rotated during pulling. The top of the projection may have a diameter of 10 mm. The crystal may be of semi-conductor material or aluminium.
