Abstract
<PICT:0779383/III/1> A method of growing semi-conductor crystals comprises immersing a seed crystal in a melt of semi-conductor material containing P, N or both types of impurities and withdrawing the seed crystal slowly to permit the material of the melt to freeze on the crystal, and includes the further step of applying an electric field across the combination of the melt, the freezing interface, and the partially grown crystal to control the spatial distribution of the impurities in the finished crystal. In operation, the crucible 1, Fig. 1, mounted upon an insulating block 2 contains for example a melt 4 of germanium or selenium with impurities, and is heated by an induction coil 6, the seed crystal 8 being raised from the melt by a cable 10 passing over pulleys 11 to a member 12 slidable in the frame 3 by an electric motor 15. The electric field across the crystal, interface, and melt is provided by a D.C. through a variable resistance 27, a change-over switch 19, an electrode 21 engaging the material 4 at the bottom of the crucible, and a terminal on the crystal holder 9. As the crystal is grown the switch is closed in one direction or the other, and the field intensity may be varied by altering the resistance 27. This variation of field direction and or intensity produces a change in the distribution of each impurity in the growing crystal so that P and N type regions may be produced alternately and the crystal may be grown with any desired specific resistance.
