摘要： A method of encapsulating a semiconductor device. The encapsulation method includes a semiconductor chip package assembly having a spacer layer between a top surface of a sheet-like substrate and a contact bearing surface of a semiconductor chip, wherein the substrate has conductive leads thereon, the leads being electrically connected to terminals on a first end and bonded to respective chip contacts on a second end. Typically, the spacer layer is comprised of a compliant or elastomeric material. A protective layer is attached on a bottom surface of the substrate so as to cover the terminals on the substrate. A flowable, curable encapsulant material is deposited around a periphery of the semiconductor chip after the attachment of the protective layer so as to encapsulate the leads. The encapsulant material is then cured. Typically, this encapsulation method is performed on a plurality of chip assemblies simultaneously.

摘要： A semiconductor chip connection component having numerous leads extending side-by-side across a gap in a support structure, each lead having a frangible section to permit detachment of one end of the lead from the support structure in a bonding process. The frangible sections are formed by treating the lead-forming material in an elongated treatment zone extending across the regions occupied by numerous leads. The process avoids the need for especially fine etching to form notches in the lateral edges of the leads.

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 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 method of packaging a semiconductor chip assembly includes the encapsulation of the same after establishing an encapsulation area and providing a physical barrier for protecting the terminals of a chip carrier. An alternative or supplement to providing a physical barrier is to provide a preform of an encapsulation material which includes a predetermined volume of such material so that only the encapsulation area is filled. For a semiconductor chip assembly which does not yet have an elastomeric layer, a method of simultaneously forming such an elastomeric layer and encapsulating a semiconductor chip assembly is also provided.

At least one lead incorporates a plural set of connecting regions connecting the bond region of that lead to a plurality of terminals. One or more of the connecting regions in each such plural set are severed so as to leave less than all of the terminals associated with each such plural set connected to the contacts of the chip.

摘要： The present invention provides an interconnection scheme having complaint contacts arranged in an array to connect conductive surfaces on a microelectronic device and a supporting substrate, such as a printed circuit board. This invention accommodates for the difference in thermal coefficients of expansion between the device and the supporting substrate. Typically, an area array of conductive contact pads are connected into rows by conductive leads on a flexible, intermediate substrate. Each of the conductive leads bridges a bonding hole in the intermediate substrate which is situated between successive contact pads. Each of the conductive leads further has a frangible portion within or near each bonding hole. A stand-off between the intermediate substrate and the device is create by compliant dielectric pads, typically composed of an elastomer material, positioned under each contact pad. The frangible portions allow the leads to be cleanly broken, bent and secured into electrical contact with chip contacts on the device. Each of these connections may be supported by a compliant layer, typically an uncured elastomer which fills the area around the compliant dielectric pads and is then cured.

摘要翻译： 本发明提供了一种具有布置成阵列中的投诉触点的互连方案，以连接微电子装置上的导电表面和诸如印刷电路板的支撑基板。 本发明适用于器件和支撑衬底之间的热膨胀系数的差异。 通常，导电接触焊盘的区域阵列通过柔性中间衬底上的导电引线连接成行。 每个导电引线桥接位于连续接触焊盘之间的中间衬底中的结合孔。 每个导电引线还在每个结合孔内或附近还具有易碎部分。 中间基板和器件之间的间隔是通过位于每个接触垫下方的通常由弹性体材料组成的柔性介电垫产生的。 易碎部分允许引线被干净地折断，弯曲并固定成与设备上的芯片触点电接触。 这些连接中的每一个可以由柔性层（通常为填充柔性介电垫周围区域的未固化的弹性体）支撑，然后固化。
