A thermal capacitor component which includes, on a substrate, a stack of different layers defined in the form of a mesa terminating at its upper part in an electrical contact layer, which layer is coated with an electrically and thermally conducting layer surmounted by a heat sink element in contact with the conducting layer. The heat sink element has a plane shape. In addition, the component has at least one pad including another stack of layers which is also coated with an electrically and thermally conducting layer. The heat sink element is also in contact with the conducting layer of this stack so as to conduct the heat from the heat sink element into the substrate. Such a thermal capacitor may find application in the cooling of semiconductor components.

A laser diode having an active layer which has a composition:

Shortwave semiconductor laser

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.

Gas-phase process for the production of an epitaxial layer of indum

A junction-type field-effect structure has an active layer covered at least in part by a dielectric layer. A metal base is applied to the dielectric layer.
