Abstract

In the progressive crystallization, crystal-pulling or zone-melting of a volatile semi-conductor material entirely within a pressure vessel, the required relative movement is transmitted from the upper surface of a liquid contained within the vessel and in communication with the outside of the vessel through a valved conduit, the level of which surface is raised or lowered by introducing further liquid under pressure or by running off liquid from the vessel respectively. A relative rotary movement may be effected by means of a magnetic coupling. The semi-conductor material may be selenium, tellurium, cadmium sulphide, or gallium arsenide. In one embodiment (Fig. 1), a water-cooled autoclave (1) supplied with inert gas at a pressure of up to 150 atmos contains a crucible (6) which is surrounded by a heating element (8) and is attached to a cylindrical float (4) on oil (3) in the bottom of the autoclave. A molten body contained in the crucible is progressively crystallized by opening an oil outlet valve (15), thus lowering the level of oil in the autoclave and downwardly withdrawing the crucible from the heating element. In another embodiment (Fig. 2), the autoclave contains a crucible (33) and pulling rod (29) which is attached to an annular float chamber (27) containing oil (26) and having an inlet valve (37) for oil under pressure. A crystal is pulled from melt in the crucible (33) by opening the valve, thus increasing the level of oil in the chamber and raising the rod.
