For the manufacture of tubular bodies of semiconductor material, particularly of silicon, by the precipitation of a layer in the form of a hollow cylinder on a rod or tube-shaped,electrically heated carrier in a reaction gas suitable for the deposition of the semiconductor in question, with subsequent separation of the semiconductor layer from the carrier, the carrier is differentially heated in such a manner that the generated hollow-cylinder layer is given an annular, bead-like reinforcement; the separation of the tube obtained into parts is achieved by a cut made within the reinforcement.
