摘要:
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.
摘要:
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 microelectronic chip comprises two parallel main faces and side faces. At least one of the faces comprises a recess provided with at least one electrical connection element and forming a housing for a wire element. The wire element simultaneously constitutes both an electrical connection between the chip and the outside via said connection element and a flexible mechanical support for said chip.

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.

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.
