Abstract
Epitaxial deposition on a semiconductor substrate of a semiconductor layer from a material in the liq. phase, partic. for the industrial prodn. of Ga-As epitaxial layers on a GaAs substrate, by the known technique in which the substrate is placed in a crucible situated in an enclosure subjected to thermal radiation from a furnace and is divided into at least two chambers by a mobile partition by displacement of which the substrate can be brought into contact with the liquid phase material, (a) the substrate is placed in a recess in a mobile situated below the mobile partition and can be withdrawn from the crucible, (b) the substrate is brought into contact with the whole of the material in the liquid phase and after completion of the epitaxial deposition, the excess liq. phase is isolated from the substrate by displacement of the mobile partition, the substrate then being withdrawn from the crucible by displacement of the mobile support, leaving the excess liq. phase material for a subsequent epitaxial deposition. Possible contamination of the liq. phase and the complicated manipulations are avoided.
