  • Method of fabricating optoelectronic components
    Patent number: 5388548
    Abstract: A method of fabricating a plurality of optoelectronic components on a semiconductor substrate, each optoelectronic component comprising several layers grown in a reactor. Every layer is being grown under a predetermined individual pressure. The active layers of all the components are lying substantially at the same height. Control of the pressure in the reactor during growth allows the thickness of the layer grown to be constant or to vary over the substrate area.
