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 method enables an assembly of chips, initially formed on a wafer, to be formed. Each chip comprises two parallel main faces joined by side faces. At least one of the side faces comprises at least one groove for housing a thread element. The wafer is first of all stuck onto a flexible film and the chips are then cut. The film is then deformed to space the chips apart from one another and to make the grooves accessible. A daisy chain is then formed joining the chips via at least one thread element, each chip being inserted in the daisy chain by inserting the thread in the groove of said chip and then removing the chip from the deformable film.

A method for forming a sheathed wire includes the steps of: axially advancing a core through a sheathing zone; wrapping a sheathing fiber around the core in the sheathing zone; and providing, in the sheathing zone, a series of microelectronic chip elements each provided with a wire section, in such a way that the sheathing fiber that wraps around the core also wraps around a chip element and the wire section thereof to form a sheathed wire incorporating spaced-apart chip elements.

A first step of the method for assembling a wire element with an electronic chip comprises arranging the wire element in a groove of the chip delineated by a first element and a second element, joined by a link element comprising a plastically deformable material, and a second step then comprises clamping the first and second elements to deform the link element until the wire element is secured in the groove.

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.

The method relates to production of a set of chips mechanically interconnected by means of a flexible connection. The chips, integrated on a substrate, each comprise a receiving area. The chips of the set are connected in series in the receiving areas by a connecting element. The chips are then released, the connecting element forming a flexible connection.

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.

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.
