Abstract
Apparatus is described for capacitively signalling 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 signalling, and reduces or eliminates the requirements for exotic metallurgy.
