Abstract
A method for encapsulating a microcomponent positioned on a substrate, including: a) production of an electrical contact pad on the substrate; b) production of a portion of sacrificial material covering the microcomponent and the electrical contact pad; c) production of an encapsulation layer covering the sacrificial material and a first face of the substrate; d) production, through the substrate, of a hole aligned with the electrical contact pad and emerging at the portion of sacrificial material; e) elimination of the portion of sacrificial material through the hole; f) production, in the hole, of a conductive portion electrically connected to the electrical contact pad, forming a conductive via.
