Abstract
Embodiments of the invention provide a multi-layer integrated circuit (IC) structure that includes a back-end-of-line (BEOL) region at a first side of a wafer. A backside region is at a second side of the wafer that is opposite the first side of the wafer. A set of signal lines are in the BEOL region, and a set of power rails are in the backside region. The set of signal lines includes a substantially constant signal-line pitch between each signal line in the set of signal lines. The set of power rails includes a substantially varying power-rail pitch between each power rail in the set of power rails.
