Method of manufacturing electric devices.

摘要

A method of manufacturing a light emitting diamond electric device is described. Discrete single crystals of diamond are formed on a semiconductor substrate by a CVD process. The formation of these crystals is carried out by forming discrete crystallization centres on the surface of the substrate and growing a single crystal at each centre. The spaces separating the crystals are filled with an electrically insulating material with the top surfaces of the crystals left exposed, and an upper electrode is provided over the insulating material and making contact with the top surfaces of the diamond crystals. When a voltage is applied between the substrate and the upper electrode, current flows in the crystals and causes them to emit light. By virtue of this method, light emitting devices having high reliability and performance can be mass produced with high yield.
