<p>The semiconductor has a localised light emitting or luminescent region which can be tailored to the physical requirements of fibre-optics etc.. The manufacturing technique has a min. number of processing stages. The semiconductor design is based on the use of a luminescent material whose area (3) and that of the active part to its associated P/N junction is circumscribed by a quasi-isolating region (4). The thickness is chosen such that the current circulating between the electrodes (6, 7) has a high value at the level of the junction, the current distribution due to its restriction within the volume providing a high intensity emission for a comparatively low basic current value.</p> |
