ABSTRACT:
In wafer-scale-integrated assemblies, microminiature transmission lines are utilized as interconnects on the wafer. The extremely small cross-sectional area of a typical such line results in its total line resistance being relatively large. Such a line exhibits signal reflections and resonances. In practice, it is not feasible to eliminate these effects by conventional load termination techniques. As a result, the frequency at which digital signals can be transmitted over such a line is typically limited to well below its so-called resonance limit. In accordance with a feature of the invention, the structural parameters of each line are selected to meet specified design criteria that ensure optimal high-frequency performance of the line.
