  • Etching method
    Patent number: 4705593
    Abstract: Materials whose elemental constituents are selected from groups III and V of the Periodic Table are photochemically etched in a reducing environment. Etching is carried out by illuminating a halogenated hydrocarbon gas, e.g. methyl iodide, with ultra-violet light in the vicinity of the material. The reducing environment is provided by the presence of sufficient hydrogen to suppress the effect of any oxygen leaking into the system.Methods according to the invention may be used in particular in the production of opto-electronic devices.
