Abstract

<PICT:0907510/III/1> A process for producing ultra-pure semi-conductor materials, such as silicon, germanium, or gallium phosphide and nitride as described in the parent Specification by chemical conversion of the gaseous metal compounds (e.g. SiHCl3 or SiCl4) and precipitation of the material produced on to a carrier body consisting of or including that material heated by an electric current (preferably A.C.) flowing through it and which may be controlled by an inductive resistance element, is effected in a reaction vessel which includes two chambers with at least one common wall 3, wherein one chamber contains the carrier body 6, 7 and 8 mounted on supports 11 and 12 contained and preferably fixed on a wall 1 in the other chamber. Inlet and exhaust tubes 4 and 5 are preferably fitted in these chambers respectively. The supports may be partially made from carbon or silicon, and quartz may be used in the construction of the chambers. The reaction gas (e.g. a mixture of H2 or A, and SiHCl3 or SiCl4) is introduced through the inlet tube into the chamber containing the carrier body and the spent gas through the holes 13 and 14 into the lower chamber.
