Abstract: A connector system for selectively coupling in a desired manner the input/output terminals of an integrated circuit chip to the input/output terminals of one or more other integrated circuit chips or to a circuit interface pin. The system includes, for each of the chips, an insulating mesa member mechanically attached to a surface of the chip. Each of the mesa members has a surface having a plurality of conductive pads disposed thereon, each of the pads being conductively coupled to the input/output terminals of the associated chip. A substrate having a recess made therein is provided with a plurality of conductive pathways. The recess defines a region of the underlying substrate, the region being provided with resilient compressible conductive pedestals, the pedestals being conductively coupled to the pathways within the region.

Abstract: Apparatus is disclosed for providing microelectronic, intra-chip and chip-to-chip interconnections in an ultra-dense integrated circuit configuration. Compressive pedestals 20 are used to form spring-loaded electrical and mechanical interconnections to conductive terminals on a chip interface mesa and chip assembly 28 in order to form a large multi-chip array 23 on an interconnection substrate 24. Methods are also disclosed for fabricating the compressive pedestals 20.

Abstract: Apparatus is disclosed for providing microelectronic, intra-chip and chip-to-chip interconnections in an ultra-dense integrated circuit configuration. An inverted chip carrier 36 comprises a carrier 35 between an improved interconnection device 37 and a semiconductor chip 12. The carrier 37 includes a mesa portion 52 bearing an array of conductive connectors 50 extending above ledge portions 54. Ledge terminals 56 are connected to the connectors 50 atop the mesa 52 by internal carrier conductors 51 and are connected to chip 12 through short, straight wires 58 that are coupled to chip 12 at conductive pads 60. Carrier 35 and chip 12 together form a sub-assembly 39 which mates with an array of complementary connectors 48 on the lower surface of an improved interconnection device 37. The present invention eliminates undesirable and wasteful looped wirebonds and provides substantial increases in volume available for active circuitry per planar die area.
