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.

An apparatus for assembling chip devices on a wire, each chip device comprising two substantially parallel lateral walls, and a groove in one of the lateral walls for receiving said wire. The apparatus includes a pinching device having two opposing surfaces, the distance between the opposing surfaces being substantially constant and substantially equal to the distance between the two lateral walls of a chip device. A wire feeder is adapted to continuously feed the wire in contact with one of the opposing surfaces of the pinching device. A chip device feeder is adapted to drive chip devices, one at a time, between the opposing surfaces, with their grooves turned towards the wire. The pinching device may comprise two cylindrical rollers having rotation axes substantially perpendicular to the wire, the opposing surfaces being formed by respective surfaces of the rollers.

Assembly of at least one microelectronic chip with a wire element, the chip comprising a groove for embedment of the wire element. The wire element is a strand with a longitudinal axis substantially parallel to the axis of the groove, comprising at least two electrically conducting wires covered with insulator. The chip comprises at least one electrically conducting bump in the groove, this bump being in electric contact with a stripped area of a single one of the electrically conducting wires of the strand.

The invention relates to the fabrication of radiofrequency transmission/reception devices. The invention makes provision for: the making of radiofrequency transmission/reception chips devoid of antennas; the connecting in series of the chips by at least two conducting wire elements whose respective lengths between two neighboring chips are chosen as a function of the transmission/reception frequency, each element contacting electrically at least one terminal of a chip and ensuring an at least temporary function of mechanical holding of the chips chainwise; and the cutting at regular intervals of the serial connection to form, for each chip, two strands of an antenna of the device.

The invention relates to a miniaturized accelerometer of the type with spring compensation of the gravity effect. The accelerometer seismic mass (1), its support and the compensating spring (2) are produced in the same substrate (10), regulating means being provided for placing the spring under mechanical tension.
摘要:
An accelerometer includes a seismic mass which is subjected to a force when accelerated. The seismic mass is connected to a support by a mechanical connection which can bend under the influence of the force. A detector is provided to determine the acceleration induced in the seismic mass by the force. Compensation can be provided for the force exerted on the mass due to gravity. The mechanical connection includes at least one component which provides compensation and induces in the mechanical connection a prestress counteracting the force exerted on the mass by gravity.
摘要:
A method for assembling a device on two substantially parallel taut threads. The device includes an electronic chip and two substantially parallel grooves open on opposite sides of the device. The distance separating the grooves corresponds to the distance separating the threads. The device presents a penetrating shape along an axis perpendicular to the plane of the grooves, having a base at the level of the grooves and an apex of smaller size than the distance separating the threads. The method includes the steps consisting in placing the apex of the device between the two threads; in moving the device between the two threads resulting in the threads being separated from one another by the penetrating shape of the device; and in continuing movement of the device until the threads penetrate into the grooves reverting to their initial separation distance.

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 neighboring 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 assembly comprises at least one microelectronic chip having two parallel main surfaces and lateral surfaces, at least one of the lateral faces comprising a longitudinal groove housing a wire element having an axis parallel to the longitudinal axis of the groove. The groove is delineated by at least two side walls. The wire element is secured to the chip at the level of a clamping area between at least one bump arranged on one of the side walls, and the side wall of the groove opposite said bump. The clamping area has a smaller height than the diameter of the wire element and a free area is arranged laterally to the bump along the longitudinal axis of the groove. The free area has a height, corresponding to the distance separating the two side walls, that is greater than the diameter of the wire element.
