摘要： A method for providing a flexible lead for a microelectronic device. A lead such as nickel or a nickel alloy is provided in elongated strips on a base material such as copper, which in turn overlies a dielectric sheet. The base material is etched from beneath bond regions of the lead material strips and a cover layer of a bondable material such as gold selectively provided around the lead material strips. The lead material strips act as plating mandrels, and allow rapid deposition of the cover material. A detachment area may be provided in each lead so that the leads may be detached and displaced within a bonding window in the dielectric sheet for attachment to chip contacts.

摘要： A connector for microelectronic elements includes a sheetlike body having a plurality of active contacts arranged in a regular grid pattern. The active contacts may include several sheetlike metallic projections extending inwardly around a hole in the sheetlike element, on a first major surface of the sheetlike element. A support structure such as a grid array of noncollapsing structural posts is on a second major surface of the sheetlike element, and each of the posts is electrically connected to one of the active contacts. The grid array of posts and the grid array of active contacts are offset from one another so that an active contact is surrounded by several posts. The posts support the sheetlike element spaced away from a substrate to which the posts are attached. A microelectronic element having bump leads thereon may be engaged by contacting the bump leads with the active contacts, and deflecting the sheetlike element between the bump leads on one side and the posts on the other side. The assembly can be tested, and if found acceptable, the bump leads can be permanently bonded to the contacts.

摘要： A semiconductor chip connection component is provided with an adhesive, desirably in a solid, non-tacky condition on its bottom surface. The adhesive may be present in a pattern covering less than all of the component bottom surface, so as to provide a void-free interface when the adhesive bonds the component to the top surface of a chip. The adhesive desirably is brought to a flowable condition by heat transferred from the chip itself. The connection component may include leads having base metal strips in a trace area underlying the top surface and noble metal portions protruding beyond an edge of the top layer. A flowable, curable material encapsulates the base metal sections. Because the base metal sections desirably are free of undercuts, the same can be encapsulated in a void-free manner during formation of the component.

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.

摘要： A microelectronic connection component includes a support such as a dielectric sheet having elongated leads extending along a surface. The leads have terminal ends permanently connected to the support and tip ends releasably connected to the support. The support is juxtaposed with a further element such as a semiconductor chip or wafer, and tip ends of the leads are bonded to contacts on the wafer using a bonding tool advanced through holes in the support. After bonding, the support and the further element are moved away from one another so as to deform the leads.

摘要： A flexible sheet used in manufacture of microelectronic components is held on a frame formed from a rigid material so that the frame maintains the sheet under tension during processing and thereby stabilizes the dimensions of the sheet. The frame may be formed from a rigid, light-transmissive material such as a glass, and the bond between the frame and sheet may be made or released by light transmitted through the frame. Preferred features of the framed sheet minimize entrapment of processing liquids such as etch solutions, thereby minimizing carryover of processing solutions between steps. The frame may have contact openings which permit engagement of a metallic layer on the sheet by an electrode carrying electroplating or etching current without disturbing the main portion of the sheet where features are to be formed or treated.

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.
