Abstract

A process and an apparatus for epitaxy in a gaseous phase, producing thin and homogeneous layers of monocrystalline indium phosphide. The process comprises two steps. In the first step, the phosphine is decomposed in a pyrolysis chamber which extends through a kiln in accordance with the reaction: ##EQU1## Thereafter, in a second step, the phosphorus is reacted with triethylindium in an atmosphere of hydrogen and nitrogen: ##EQU2## The residual gases are drawn off by a vacuum pump.
