Abstract
A technique for providing a multi-layer substrate which is capable of signal transmission at multiple propagation speeds is disclosed. In one embodiment, the technique is realized by constructing a multi-layer substrate by creating air channels in dielectric layers adjacent to a conductor. The air channels may also be filled with an alternative dielectric material. At least three types of multi-layer substrates may be produced through this technique. Furthermore, signal tracks of varying lengths can be provided to accommodate differing delays.
