Abstract:
Method of collectively packaging a plurality of electronic components formed in a first substrate, wherein the electronic components are separated from one other by separation strips associated with a plurality of conducting tracks formed on a second substrate. The conducting tracks on the second substrate are associated with contact pads of the components in the first substrate. Each conducting track on the second substrate includes a connection strip arranged to coincide with associated depressions in the first substrate when the first and second substrates are mated. After mating, the components are separated into individualized electronic modules by forming proximal trenches in the first substrate and distal trenches in the second substrate. The proximal trenches are formed around the components in the first substrate to open up into the depressions in the first substrate. The distal trenches are formed further away from the components than the proximal trenches in regions comprising the connection strips on the second substrate.

Abstract:
A support designed for hybrid optoelectronics, including at least one integrated optical guide and including a substrate on which the optical guide has been created by depositing a suitable material on the substrate to create a lower confinement layer, a guide core layer, and an upper confinement layer. The optical guide is designed to be optically connected to an optoelectronic component mounted on the support, in which the support positions the component to ensure its optical alignment with the optical guide. The support includes abutments located at the core level, or defined in a confinement layer in relation to the core layer, to ensure the vertical positioning of the component. The invention also relates to processes for producing the support.
