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 module has a stack (100) of two slices (10, 30), where the slice (10) has a set of electrically conducting bumps on its face. The slice (30) comprises an electrically insulating material zone (61) passing through the thickness of the slice (30) and an electrically conducting element (3) passing through the slice (30) in the zone. The conducting element and the bumps are made of material having a determined hardness. The hardness of the material of the element (3) is lower than the hardness of the material of the bumps so that the bumps penetrate in the conducting element.

Abstract: The method involves transferring electronic components on the upper surface of a printed circuit (51). A resin layer (52) is deposited on the upper surface to ensure mechanical holding of the components. A wafer is surfaced in order to permit appearance of conducting zones of external outputs of the components on a connection surface (55) of the wafer, where the zones are connected. An independent claim is also included for an electronic device comprising a set of components.

Abstract: The present invention relates to an electronic device incorporating a heat distributor. It applies more particularly to devices of the plastic package type, with one or more levels of components. According to the invention, the electronic device, for example of the package type, is provided for its external connection with pads distributed over a connection surface. It includes a thermally conducting plate lying parallel to said connection surface and having a nonuniform structure making it possible, when the device is exposed to a given external temperature, to supply a controlled amount of heat to each external connection pad according to its position on the connection surface. If the device is a package comprising a support of the printed circuit type, the conducting plate will advantageously form an internal layer of said support.

Abstract: La présente invention concerne un dispositif électronique intégrant un répartiteur de chaleur. Il s'applique plus particulièrement aux dispositifs de type boîtiers plastiques, à un ou plusieurs niveaux de composants.Selon l'invention, le dispositif électronique, par exemple de type boîtier, est muni pour sa connexion externe de plots (11) répartis sur une surface de connexion (22), Il comprend une plaque (23) conductrice de la chaleur, disposée parallèlement à la dite surface de connexion, et présentant une structure non uniforme permettant, lorsque le dispositif est soumis à une température extérieure donnée, un apport de chaleur contrôlée au niveau de chaque plot de connexion externe, en fonction de sa position sur la surface de connexion.Dans le cas où le dispositif serait un boîtier comprenant un support (20) de type circuit imprimé, la plaque conductrice formera avantageusement une couche interne dudit support.
