An interconnecting substrate according to the invention comprises an insulating base on which rests a set of alternating, superimposed conductive and insulating layers. Contacts are formed on the uppermost insulating layer which border at least one site or zone intended for an integrated circuit chip device whose output conductors are to be connected to the said contacts. Through-connections enable the contacts to be coupled to one of the inner conductive layers. The through-connections include at least one through-connection on the inside of the site relative to at least a predetermined one of the said contacts. A shunt conductor means connected to the predetermined contact has a part outside the site which is connected to an additional contact which serves as a substitute or replaces the said predetermined contact for the connection to the associated output conductor of the chip device. The repair arrangement according to the invention allows one to substitute for a connection inside a site over which a chip is situated between a contact and a through-connection, a link which has a part outside the site from which it is possible to make a repair or modification of the circuit function without the need to remove the component. The repair arrangement is made up of conductive and insulating layers which are deposited at least locally on the substrate.

Substrate for interconnecting electronic integrated circuit components

A standardized access card is formed of a single or a pair of bonded sheets f material including a cavity within which is disposed an integrated circuit assembly for processing electrical signals arranged within the card. The thickness of the assembly is relatively smaller than the thickness of the card and terminal areas of the assembly are accessible through cut-outs in the card which may be open or plugged with conductive material. The card may be formed in a continuous process from a plurality of strips of material which separately provide the card material, the integrated circuit assembly and a cover for the device of the circuit assembly.

A method of fabricating a carrier support for integrated circuit chips to be mounted subsequently on a substrate. A flexible strip of an inextensible insulating material is provided with equidistant openings in the center of each of which a chip is to be mounted. One of the faces of this strip is covered with a conductive film, the said film is cut away to form in each opening interface conductors which overhang towards the center of the opening. Before the conductive film is cut away, the film is coated with a layer of photosensitive lacquer which is partly removed to enable the film to be laid bare in regions which, in each opening, form part of an open-centered zone which surrounds that portion of the film in which the free inner ends of the interface conductors associated with this opening are to be produced. The bared regions in this opening either consist of the whole of the said open-centered zone or else consist of those portions of the zone which are located at least at the points where the said zone is crossed by the outlines of the future interface conductors associated with this opening. A layer of synthetic resin electrodeposited on the bared regions of the film and thereafter the remaining portions of the photosensitive lacquer are removed, as a result of which there is no danger of the interface conductors resulting from the film being cut away causing short circuits when, after the chips have been mounted on their free inner ends, the conductors are cut at a short distance from the edges of each chip so that they may finally be soldered to the said substrate.
