Abstract
A method of manufacturing an ECO base cell includes forming first and second active areas on opposite sides of, and having corresponding long axes arranged parallel to, a first axis of symmetry; forming non-overlapping first, second and third conductive structures having long axes in a second direction perpendicular to the first direction and parallel to a second axis of symmetry, each of the first, second and third conductive structures to correspondingly overlap the first and second active areas, the first conductive structure being between the second and third conductive structures; removing material from central regions of the second and third conductive structures; and forming a fourth conductive structure being over the central regions of the second and third conductive structures and occupying an area which substantially overlaps a first segment of the first conductive structure and a first segment of one of the second and third conductive structures.
