Abstract:
A hermetic coupling device between an optoelectronic component emitting and/or receiving a light beam, and an optical transmission mechanism conveying the light beam. The hermetic coupling device includes a substrate including a blind hole, having a bottom wall, into which one part of the optical transmission mechanism is inserted. The substrate is formed of a stack of a first layer and a second layer. The light beam crosses the substrate passing through the bottom wall of the blind hole, the substrate receiving the optoelectronic component substantially opposite the blind hole. Reflective patterns are inserted between two layers of the hermetic coupling device, substantially on the periphery of the blind hole, and reflect one part of the light beam emitted by the optoelectronic component.

This method of coating the area of hybridization of a component constituted by two elements associated with one another by means of a soldering material, comprises depositing in proximity to said component a coating substance capable of filling by capillarity the volume defined between the hybridized elements of said component. On the periphery of the hybridization area on the lower element of said component is defined an area (10) of non-wettability as regards said substance, by deposition of a covering anti-wetting as regards said substance, applied by PECVD, and defining on said first element, in line with the hybridization, a wetting surface for the coating substance.
