摘要:
A substrate provided with an electrically conducting wire coated with an electrically insulating material is impregnated with a polymerizable material. A reception area for a chip is formed on a surface of the substrate by means of deformation. The housing area is stiffened using the polymerizable material. The chip is disposed in the reception area and an electrical connection area of the chip is connected electrically to the electrically conducting wire of the substrate.

The invention relates to a method for producing chip elements provided with a groove, comprising the following steps: on an interconnect substrate, providing a conductive track arranged to connect a contact area of an active surface of a chip to an area corresponding to a first wall of the groove; growing a contact bump by electrodeposition on the conductive track at the level of the area corresponding to the first wall of the groove; assembling the chip on the substrate via its active surface so that a side wall of the chip forms the bottom of the groove; machining the chip via its rear surface in parallel to the substrate while measuring the distance between the rear surface of the chip and the contact bump; stopping machining when the measured distance reaches a required value; and assembling by bonding a plate to the rear surface of the chip so as to form a second wall of the groove.

This invention relates to a stacked electronic device composed of stacked electronic components (120, 130) distributed on one or several added-on levels (N2, N3) each added on the preceding level starting from a base level (N1) possibly containing at least one electronic component (110). At least one electrolytic connection pad of a first type (10.1) on an add-on level (N2) directly connects a conducting element (c1) placed on one face of an electronic component (120) on an add-on level (N2) to a conducting element (z1) placed on an opposite face of a neighbouring level (N1) while at least one electrolytic connection pad of a second type (20.1) on the add-on level (N2) passes through a coating layer (220) coating the sides of the electronic component (120) on the add-on level (N2) and directly electrically connects two conducting elements (z1, z2) located on each side of said coating layer (220).

The electrodes are formed by surface coating and cold compression on metal strips. They are then assembled, by hot pressing, with an electrolytic membrane. The metal strips are then removed, preferably by mechanical detachment. Current collectors are then formed on each of the electrodes by PVD type techniques that are conventional in microelectronics. The resulting thin micro-battery with high surface capacity can then be integrated in an integrated circuit, in particular by bonding by means of indium connecting balls.

This invention relates to a process for manufacturing an anisotropic conducting film comprising a layer of electrically insulating material and conducting through inserts, the said process comprising the following steps: a) formation on a substrate of at least one layer of material with through holes, the said layer being called the perforated layer, b) filling of the through holes to form conducting inserts. The process also comprises production of a mask partially covering a first end of the conducting inserts and etching of the unmasked part of the ends of the conducting inserts so as to obtain conducting inserts with pointed ends. The invention is applicable to the formation of components (chips, integrated circuits) with a high interconnections density.

The method for assembling a microelectronic chip device (101) in a fabric (104) comprises the following steps: providing a microelectronic chip device (101) comprising a base (102) and a protruding element (103) rising from a face of the base (102), said protruding element (103) comprising a free end opposite the base (102); inserting into the fabric (104) the chip device (101) by the free end of the protruding element; deforming the protruding element (105) at its free end so as to ensure the securing of the chip device (101) with the fabric (104) by forming a crimping bead (106).
摘要:
A method for producing a structure includes bonding two substrates facing one another by crushing a closed peripheral sealing strip located between the two substrates, the closed peripheral sealing strip delineating a closed cavity between the substrates. A microsystem is disposed on one of the substrates within the closed cavity. Before crushing, the sealing strip includes perforated patterns delineating a plurality of voids inside the strip.
