摘要： A connection component for use in making microelectronic element assemblies which has peelable leads that are formed on a dielectric support structure. One end of each lead is permanently connected to the support structure and the opposite end of the lead is releasably connected to the support structure. When the releasable end of the lead is bonded to a contact on a semiconductor chip, the releasable end of the lead can be peeled from the support structure such that the chip may be moved away from the support structure. A compliant layer may be disposed between the chip and the support structure. If a compliant material is injected between the chip and the support structure to form the compliant layer, the compliant material will lift the chip away from the support structure and facilitate the peeling of the leads from the support structure.

摘要： A structure including a conductive, preferably metallic conductive layer is provided with leads on a bottom surface. The leads have fixed ends permanently attached to the structure and free ends detachable from the structure. The structure is engaged with a microelectronic element such as a semiconductor chip or wafer, the free ends of the leads are bonded to the microelectronic element, and the leads are bent by moving the structure relative to the microelectronic element. Portions of the conductive layer are removed, leaving residual portions of the conductive layer as separate electrical terminals connected to at least some of the leads. The conductive layer mechanically stabilizes the structure before bonding, and facilitates precise registration of the leads with the microelectronic element. After the conductive layer is converted to separate terminals, it does not impair free movement of the terminals relative to the microelectronic element.

摘要： A substantially continuous layer of a first metal such as copper is provided with strips of a second metal such as gold by selective electroplating of the second metal, or by applying separately formed strips such as lengths of wire. A dielectric support layer is provided in contact with the first metal layer, and the first metal layer is etched to leave strips of the first metal contiguous with the strips of the second metal, thereby providing composite leads with the first and second metal strips connected in series. The process provides simple and economical methods of making microelectronic connection components with leads having a flexible, fatigue resistant lead portion formed from a precious metal. The leads may incorporate sections of round cross-sectional shape to facilitate engagement by a bonding tool during use of the component.

摘要： A connector for microelectronic elements includes a sheet-like body having a plurality of holes, desirably arranged in a regular grid pattern. Each hole is provided with a resilient laminar contact such as a ring of a sheet metal having a plurality of projections extending inwardly over the hole of a first major surface of the body. Terminals on a second surface of the connector body are electrically connected to the contacts. The connector can be attached to a substrate such a multi-layer circuit panel so that the terminals on the connector are electrically connected to the leads within the substrate. Microelectronic elements having bump leads thereon may be engaged with the connector and hence connected to the substrate, by advancing the bump leads into the holes of the connector to engage the bump leads with the contacts. The assembly can be tested, and if found acceptable, the bump leads can be permanently bonded to the contacts.

摘要： Microelectronic contacts, such as flexible, tab-like, cantilever contacts, are provided with asperities disposed in a regular pattern. Each asperity has a sharp feature at its tip remote from the surface of the contact. As mating microelectronic elements are engaged with the contacts, a wiping action causes the sharp features of the asperities to scrape the mating element, so as to provide effective electrical interconnection and, optionally, effective metallurgical bonding between the contact and the mating element upon activation of a bonding material.

A mass of fusible conductive material having a melting temperature below about 150° C. is disposed in each of said cavities, the dielectric material electrically insulating the masses of fusible conductive material from one another. A probe tip of conductive material having a melting temperature greater than about 150° C. is provided at one common end of each of the masses of fusible conductive material. The probe contacts are separated from an adjacent probe contact by at least one channel formed with the layer of dielectric material.

摘要： An interposer for interconnection between microelectronic circuit panels has contacts at its surfaces. Each contact has a central axis normal to the surface and a peripheral portion adapted to expand radially outwardly from the central axis responsive to a force applied by a pad on the engaged circuit panel. Thus, when the circuit panels are compressed with the interposers, the contacts expand radially and wipe across the pads. The wiping action facilitates bonding of the contacts to the pads, as by conductive bonding material carried on the contacts themselves.

摘要： Microelectronic contacts, such as flexible, tab-like, cantilever contacts, are provided with asperities disposed in a regular pattern. Each asperity has a sharp feature at its tip remote from the surface of the contact. As mating microelectronic elements are engaged with the contacts, a wiping action causes the sharp features of the asperities to scrape the mating element, so as to provide effective electrical interconnection and, optionally, effective metallurgical bonding between the contact and the mating element upon activation of a bonding material.
