An apparatus for constructing, repairing and operating modular electronic systems utilizes peripheral half-capacitors (i.e., conductive plates on the outside of the modules) to communicate non-conductively between abutting modules. Such systems provide lower cost, improved testability/reparability and greater density than conventional modular packaging techniques, such as printed circuit boards and multi-chip modules. The non-conductive interconnection technique of the invention can be applied to all levels in the packaging hierarchy, from bare semiconductor dies to complete functional sub-units. Numerous exemplary systems and applications are described.

Apparatus for non-conductively interconnecting integrated circuits

Methods and apparatus are described for capacitively signaling between different semiconductor chips and modules without the use of connectors, solder bumps, wire-bond interconnections or the like. Preferably, pairs of half-capacitor plates, one half located on each chip, module or substrate are used to capacitively couple signals from one chip, module or substrate to another. The use of plates relaxes the need for high precision alignment as well as reduces the area needed to effect signaling, and reduces or eliminates the requirements for exotic metallurgy.
