Coaxial wiring within SOI semiconductor, PCB to system for high speed operation and signal quality

An integrated circuit is provided that contains a coaxial signal line formed at least partially within a silicon-containing substrate. The coaxial signal line comprises an inner conductor having a length, said length axially surrounded by, and insulated from, an outer conductor along said length. A method of preparing such an integrated circuit having said coaxial signal line formed at least partially within a silicon-containing substrate is also disclosed herein.
