Abstract:
A photolithographically patterned spring contact (15) is formed on a substrate (14) and electrically connects pads (3) on two devices. The spring contact (15) also compensates for thermal and mechanical variations and other environmental factors. An inherent stress gradient in the spring contact causes a free portion (11) of the spring contact to bend up and away from the substrate. An anchor portion (12) remains fixed to the substrate (14) and is electrically connected to a first contact pad (3) on the substrate (14). The spring contact (15) is made of an elastic material and the free portion (11) compliantly contacts a second contact pad (3), thereby electrically interconnecting the two contact pads.
Abstract:
A microelectronic spring contact for making electrical contact between a device and a mating substrate and method of making the same are disclosed. The spring contact has a compliant pad adhered to a substrate of the device and spaced apart from a terminal of the device. The compliant pad has a base adhered to the substrate, and side surfaces extending away from the substrate and tapering to a smaller end area distal from the substrate. A trace extends from the terminal of the device over the compliant pad to its end area. At least a portion of the compliant pad end area is covered by the trace, and a portion of the trace that is over the compliant pad is supported by the compliant pad.
Abstract:
A connector (10) for microelectronic elements includes a sheetlike body (24) having a plurality of active contacts (22) arranged in a regular grid pattern. The active contacts (22) may include several metallic projections (28) extending inwardly around a hole (27) in the sheetlike element (24), on a first major surface (32). A support structure such as a grid array of noncollapsing structural posts (23) is on a second major surface (33), and each of the posts (23) is electrically connected to one of the active contacts (22). The grid array of the posts (23) and the grid array of active contacts (22) are offset from one another so that an active contact (22) is surrounded by several posts (23). The posts (23) support the sheetlike element (24) spaced away from a substrate (41) to which the posts (23) are attached. A microelectronic element (45) having bump leads (46) thereon may be engaged by contacting the bump leads (46) with the active contacts (22), and deflecting the sheetlike element (24) between the bump leads (46) on one side and the posts (23) on the other side.

Abstract:
An MCM includes a two-dimensional array of facing chips, including island chips (120-1, 120-2) and bridge chips (122) that communicate with each other using overlapping connectors. In order to maintain the relative vertical spacing of these connectors, compressible structures (124) are in cavities (114) in a substrate (110), which house the bridge chips, and provide a compressive force on the back surface of the bridge chips. These compressible structures include a compliant material with shape and volume compression. In this way, the MCM may ensure that facing surfaces of the island chips and the bridge chips, as well as connectors on these surfaces, are approximately coplanar without bending the bridge chips.
Abstract:
The invention relates to an electromechanical component (10) comprising a polymeric body (12) consisting of a mechanically active component (14a, 14b, 14c), a frame (18) and a metal layer (30). Said metal layer at least partially covers a mechanically active part in order to mechanically stabilize the same, whereby a region of the polymer body (12) carrying said metal layer (30), comprises a first polymer material which can metallicized in a wet chemical process. Another region which does not have a metal layer comprises a second polymer material which can not be metallized in a wet chemical process. Said electromechanical component can be an acceleration sensor, a rotation speed sensor, a microvalve, a micropump, a pressure sensor or a power sensor. Production of said electromechanical component incurs substantially lower costs compared to electromechanical components produced using silicon-based technology because said production process involves simple injection-molding and/or stamping instead of complicated silicon-based technology.
Abstract:
Temporary connections to spring contact elements extending from an electronic component such as a semiconductor device are made by urging the electronic component, consequently the ends of the spring contact elements, vertically against terminals of an interconnection substrate, or by horizontally urging terminals of an interconnection substrate against end portions of the spring contact elements. A variety of terminal configurations are disclosed.
Abstract:
An electronic module, and method for making same, includes free-formed, self-supported interconnect pillars that electrically connect cover electronic components disposed on a cover substrate with base electronic components disposed on a base substrate. The free-formed, self-supported interconnect pillars may extend vertically in a straight path between the cover electronic components and the base electronic components. The free-formed, self-supported interconnect pillars may be formed from an electrically conductive filament provided by an additive manufacturing process. By free-forming the self-supported interconnect pillars directly onto the electronic components, the flexibility of electronic module design may be enhanced, while reducing the complexity and cost to manufacture such electronic modules.
