Abstract
A semiconductor device includes an array of Engineering Change Order (ECO) cells. Each of the ECO cells in the array includes a first metal pattern and a second metal pattern. Each of the ECO cells in the array further includes a plurality of active area patterns isolated from each other and arranged between the first and second metal patterns. Each of the ECO cells in the array further includes a first central metal pattern overlapping the first metal pattern. Each of the ECO cells in the array further includes a via electrically connecting the first central metal pattern to the first metal pattern. The plurality of active area patterns is arranged symmetrically about the first central metal pattern.
