DUAL POWER STRUCTURE WITH EFFICIENT LAYOUT

Abstract:

Disclosed herein are related to an integrated circuit having a dual power structure with an efficient layout and a method of forming the integrated circuit. In one aspect, the integrated circuit includes a substrate, a first layer facing the substrate, and a second layer facing the first layer. In one aspect, the first layer includes a set of first metal rails, where each of the set of first metal rails may be separated from its adjacent one of the set of first metal rails according to a uniform pitch along a direction. In one aspect, the second layer includes a set of second metal rails, where the set of second metal rails may include two adjacent second metal rails separated according to a first pitch along the direction and additional two adjacent second metal rails separated according to a second pitch along the direction.
