Abstract:
The invention relates to organometallic compounds which are stabilized intramolecularly and have a cyclic or bicyclic structure and to the use thereof for the preparation of thin films and epitaxial layers by gas phase deposition.
Abstract:
A reactor for MOCVD systems, having a reaction vessel through which the reacting gas or gases flow and in which the substrates are arranged in such a manner that a main surface is approximately parallel to the flow direction. The reaction vessel is made of quartz-glass and has, at least in the region in which the reacting gas flows, a rectangular cross-section. A flange element is provided at the gas-entrance-side end of the reaction vessel, while a protective tube surrounds the reaction vessel. The protective tube is provided with a face-end reactant gas inlet connected with a flange element to which the flange element of the reaction vessel can be flanged. The protective tube has a protective gas inlet in its superficies, which permits purging the space between the reaction vessel and the protective tube, and a reactant gas outlet. The reactant gases are deflected in the reaction vessel and exit through the superficies of the reaction vessel. A diffusion barrier is provided at the end opposite the gas-entrance-side end of the reaction vessel.

Abstract:
The invention relates to the fabrication of modules consisting of a number of light-emitting elements (10) and the associated driver electronics (11) integrated on a common conductive p-type Gallium Arsenide substrate (12). The use of a number of such modules to form in a recording head an uninterrupted row of light-emitting elements is furthermore disclosed.
