Abstract: An integrated circuit chip includes a front face having an electrical connection pad. An overmolded encapsulation block encapsulates the integrated circuit chip and includes a front layer at least partially covering a front face of the integrated circuit chip. A through-hole the encapsulation block is located above the electrical connection pad of the integrated circuit chip. A wall of the through-hole is covered with an inner metal layer that is joined to the front pad of the integrated circuit chip. A front metal layer covers a local zone of the front face of the front layer, with the front metal layer being joined to the inner metal layer to form an electrical connection. The inner metal layer and the front metal layer are attached or anchored to activated additive particles that are included in the material of the encapsulation block.

Abstract: An electronic device includes a first electronic component and a second electronic. Each electronic component includes a carrier substrate having a back side and a front side, an electronic chip including an integrated optical element, an overmolded transparent block encapsulating the electronic chip above the carrier substrate, and electrical connections between the electronic chip and electrical contacts of the carrier substrate. An overmolded grid encapsulates and holds the first and second electronic components. The grid is configured so that sides of the first and second electronic components are at least partially exposed.

Abstract: A package includes an upper level mounted to a lower level. The upper level includes a stack formed by insulating layers and conductive elements and includes a first conductive track of an antenna. A plastic element rests on the stack. A first cavity is defined in the plastic element. A second conductive track of the antenna is located on a wall of the plastic element (for example, in or adjacent to the first cavity). A second cavity is also defined in the plastic element surrounding the first cavity. A third conductive track of the antenna is located on a wall of the plastic element (for example, in the second cavity). A third cavity is delimited between the upper and lower levels and an integrated circuit chip is mounted within the third cavity and electrically connected to the antenna.

Abstract: An optoelectronic element is located in a package. The package includes a first optical block and a second optical block that are attached to each other by a bonding layer. One of the first and second optical blocks is attached to lateral walls of the package by glue. The material of the bonding layer is configured to induce less stress to the first and second optical blocks than the glue.

Abstract: An electronic chip supports an optical device and electric connection zones. An insulating coating coats the electronic chip, covers the electric connection zones and exposes the optical device. An optical plugging element is at least partly fastened onto a first face of the insulating coating and is optically coupled to the optical device. Vias pass through the insulating coating from its first face to a second face opposite to the first face. Inner walls of the vias support electrically conductive paths connected to the electric connection zones of the electronic chip by electrically conductive tracks arranged on the first face of the insulating coating. The electrically conductive paths of the vias further have ends protruding onto the second face of the insulating coating.

Abstract: A non-conductive encapsulation cover is mounted on a support face of a support substrate to delimit, with the support substrate, an internal housing. An integrated circuit chip is mounted to the support substrate within the internal housing. A metal pattern is mounted to an internal wall of the non-conductive encapsulation cover in a position facing the support face. At least two U-shaped metal wires are provided within the internal housing, located to a side of the integrated circuit chip, and fixed at one end to the metallic pattern and at another end to the support face.

Abstract: An opaque dielectric carrier and confinement substrate is formed by a stack of layers laminated on each other. The stack includes a solid back layer and a front frame having a peripheral wall and an intermediate partition which delimits two cavities located on top of the solid back layer and on either side of the intermediate partition. Electronic integrated circuit (IC) chips are located inside the cavities and mounted on top of the solid back layer. Each IC chip includes an integrated optical element. Electrical connections are provided between the IC chips and back electrical contacts of the solid back layer. Transparent encapsulation blocks are molded in the cavities to embed the IC chips.

Abstract: A substrate includes a through cavity. A heat sink is mounted so as to close one end of the through cavity. An integrated circuit (IC) chip is also mounted in the cavity. Conductive wires provide an electrical connection between pads on an upper surface of the IC chip and metallizations on the substrate. The mounted heat sink is positioned within the substrate in one implementation and positioned mounted to a back surface of the substrate in another implementation.
