  • Patent number: 4261770
    Abstract: A process for producing epitaxial semiconductor material layers on monocrystalline substrates via liquid phase shift epitaxy wherein, in order to avoid bead-growth on a substrate, at least the lower region of an epitaxy solution chamber is clad with a substrate material so as to displace the location of the bead growth away from the actual substrate and toward the region of the cladding. This process is useful for producing GaAs-(Ga, Al) As and (Ga, In) (As, P) mixed crystal layers for luminescent diodes and laser diodes.
