Abstract: A method for interconnecting active and passive components in two or three dimensions, and the resulting thin heterogeneous components. The method comprises: positioning and fixing (11) at least one active component and one passive component on a flat support (23), the terminals being in contact with the support, depositing (12) a polymer layer (24) on all of the support and the components, removing the support (14), redistributing the terminals (15) between the components and/or toward the periphery by metal conductors (26) arranged in a predetermined layout, making it possible to obtain a heterogeneous reconstituted structure, heterogeneously thinning (16) the structure by nonselective surface treatment of the polymer layer and at least one passive component (22).

Abstract: The invention relates to a device for the hermetic encapsulation of a component that has to be protected from any stress. The component (5) is fastened to a substrate (15) that carries, on its other face, a temperature-regulating element (17) fastened by adhesive bonding (16). This assembly is placed in a package comprising two portions (11, 12) joined together by adhesive bonding (13) with a passage for optical links (6) and for electrical connections (18, 142). It is supported by protuberances (19) of one portion (11) of the package. Bonded to the other portion (12) is a three-dimensional interconnection block (14) forming the temperature-regulating electronics. The block, the package (11, 12) and a minimum length (L) of the links and connections are encapsulated in a mineral protective layer (4'). The invention applies especially to optoelectronic components and to MEMS components.

Abstract: The invention relates to a process for the distributed shielding and decoupling of an electronic device having integrated components with three-dimensional interconnection, to such a device and to a production process. The device comprises, associated with each active component (2), at least one capacitor plane formed from a thin sheet (10) of a dielectric, said sheet being metallized (10, 11, 12) on its two plane faces. The components and the capacitor planes are stacked in alternation and joined together to form a block (1'), the lateral faces (21 to 24) of which carry conductors (13, 14) ensuring 3D interconnection. The metallizations (11, 12) are delimited in order to be flush with the edges of the block only via tabs (110, 120). One of the metallizations (11) connected to ground serves as shielding. The invention applies especially to the production of very compact memory blocks.

Abstract: The invention concerns a method for distributed shielding and bypass for an electronic device with integrated components having three-dimensional interconnection, the inventive device and a method for making same. The device comprises, associated with each active component (2), at least a capacitor plane consisting of a thin foil (10) made of metal-coated dielectric material (11, 12) on its two planar surfaces. The components and capacitor planes are stacked and alternately assembled to form a block (1') whereof the side surfaces (21 to 24) bear conductors (13, 14) providing the three-dimensional interconnection. The metal coatings (11, 12) are delimited to be flush with the edges of the block only through tabs (110, 120). One of the metal coatings (11) connected to the ground acts as shield. The invention is particularly useful for producing very compact storage blocks.

The method also includes, in a variant of invention, for supplying power to circuits, a Bus bar, and at step (b) at least one of the grooves cuts into the extremities of two adjacent conductors; the method includes an additional step, that is (g) the cutting of second grooves in the bottom of first grooves in full length, implemented between steps (c) and (e). The width of second grooves is less than that of first grooves. The cutting of grooves is done by sawing, or by use of laser. In another variant of invention, the method comprises an additional step, that is (h) the introduction of a capacitor by bonding plates to lateral faces of groove by a conducting adhesive, which is implemented before step (e). An electronic device with interconnections in three dimensions comprising casings or circuits with connecting conductors and encapsulated to form a block, is made with grooves and metallization according to the method.
