A flexible electronic structure includes a first film, made of a first polymer or glass, and a second film, made of a second polymer, in which at least one electronic component is arranged. The second film covers the first film. The flexible electronic structure also includes at least one electrically conductive track arranged between the first film and the second film, and each electrically connected to one of the electronic components, by a respective interconnection element. Optionally, the flexible electronic structure includes a third film, made of a third polymer or glass, covering the second film. The interconnection element is arranged near the neutral plane of the structure, and the structure includes at least one compensation layer, so as to position the neutral plane at a desired location.

Method for integrating structures in a support and associated device

A box for a microelectronic device includes a first portion and a second portion able to be assembled in order to define, in an assembled position, a housing space for the microelectronic device. A face of the first portion is facing a face of the second portion in the assembled position. The first zones facing the faces form an interface for attaching the first portion and second portion. The second zones face faces forming a cavity for receiving the microelectronic device. At least one among the first portion and the second portion includes at least one element for electrical connection. The first portion and the second portion can apply at least one connection pad of the microelectronic device on the element for connection in the assembled position.
