Abstract: Described are methods for enabling the creation of multiple similar designs by utilizing sets of multiple, disjoint fabrication masks. A first set of device features may be formed from a material layer in a first portion of a die area of a semiconductor substrate based on a first photolithographic exposure. A second set of device features may be formed from the material layer in a second portion of the die area of the semiconductor substrate based on a second photolithographic exposure after the first photolithographic exposure. The first portion of the die area and the second portion of the die area may be non-overlapping.

Abstract: Described herein are mechanisms and methods for blocking the propagation of signals to Integrated Circuit (IC) components that have been power gated, rather than simply suffering from leakage through signals that might not be parked in a low state. In some embodiments, switches that block the flow of current in such signals may enable turning off power to any IC component and not just to circuits on an IC component that make sole use of protocols that are friendly to power gating. This may advantageously increase power savings, by permitting more portions of a system in an idle state to be power gated, or by reducing or eliminating leakage in signals on boundaries of blocks being power gated, or both.
