Abstract: An electronic device includes a carrier substrate having a front face. An electronic chip is mounted on the front face of the carrier substrate and includes an optical component. An encapsulation cover is mounted on top of the front face of the carrier substrate and bounds a chamber within which the chip is situated. A front opening extends through the cover and is situated in front of the optical component. An optical element, designed to allow light to pass, is mounted within the chamber at a position which covers the front opening of the encapsulation cover. The optical element includes a central region designed to deviate the light and having an optical axis aligned with the front opening and the optical component. A positioning pattern is provided on the optical element to assist with mounting the optical element to the cover and mounting the cover to the carrier substrate.

Abstract: An electronic device includes a carrier substrate having a front face and an electronic chip mounted on the front face. An encapsulation cover is mounted above the front face and bounds a chamber in which the chip is situated. A front opening is provided in front of an optical component of the chip. An optical element, designed to allow light to pass, is mounted on the cover in a position which covers the front opening of the cover. The optical element includes a central region designed to deviate light and a positioning pattern that is visible through the front opening. An additional mask is mounted on the encapsulation cover in a position which extends in front of the optical element. A local opening of the additional mask is situated in front of the optical component.

Abstract: A carrier substrate is configured to carry at least one electronic chip and includes a mounting front face. An encapsulating cover is mounted on the front face of the carrier substrate through a mounting. This mounting includes at least one seating surface through which the cover and the carrier substrate make contact. At least one adhesive bead is located elsewhere than the seating surface in order to securely fasten the encapsulation cover and the carrier substrate.

Abstract: An integrated circuit chip is mounted to a front face of a support plate. An encapsulation cap in then mounted to the support plate. The encapsulation cap includes a front wall and a peripheral wall having an end edge at least partly facing a peripheral zone of the support plate. The support plate and the encapsulation cap delimit a chamber in which the integrated circuit chip is situated. To mount the encapsulation cap, a bead of glue is inserted between the peripheral zone and the end edge of the peripheral wall of the encapsulation cap. A peripheral outer face of the encapsulation cap includes a recess extending from the end edge which locally uncovers a part of the bead of glue. A local hardening of the glue at the recess is performed as a first attachment step. Further hardening of the remainder of the glue is then performed.
