Abstract
A multi-level signal line architecture having signal line pairs employing vertical twists to reduce couplings noise is disclosed. The signal line pairs are provided with open regions to accommodate offsets of twists of adjacent signal line pairs, thus reducing the line pitch of the signal lines. The open region is formed by removing a portion of the signal line in the upper level and locating that portion on another level above the upper level.
