Abstract

A solid semi-conductor material (e.g. silicon or germanium) is shaped (cut, perforated or hollowed) by means of a gas jet directed thereon, the gas and/or the crystal being heated to a temperature below the melting point of the crystal, said temperature and the composition and pressure of the gas jet being such that a compound is formed between the gas and the crystal, which compound evaporates at said temperature, and the application zone of the crystal being exposed to visible or infra-red light. The gas may be chlorine, bromine, fluorine, hydrogen chloride, oxygen or ozone. The operation is effected in a vessel which is continuously evacuated. The nozzle width is between 5 and 100m .ALSO:A solid semi-conductor material (e.g. silicon or germanium) is shaped (cut, perforated or hollowed) by means of a gas jet directed thereon, the gas and/or the crystal being heated to a temperature below the melting-point of the crystal, said temperature and the composition and pressure of the gas jet being such that a compound is formed between the gas and the crystal, which compound evaporates at said temperature, and the application zone of the crystal being exposed to visible or infra-red light.
