Abstract
A process for producing a component includes a structure made of III-V material(s) on the surface of a substrate, the structure comprising at least one upper contact level defined on the surface of a first III-V material and a lower contact level defined on the surface of a second III-V material, comprising: successive operations of encapsulation of the structure with at least one dielectric; making primary apertures in a dielectric for the two contacts; making secondary apertures in a dielectric for the two contacts; at least partial filling of the apertures with at least one metallic material so as to produce upper contact bottom metallization and at least one upper contact pad in contact with the metallization for each of said contacts. A component produced by the process is also provided. The component may be a laser diode.
