    Abstract: The present disclosure relates to a method of forming a gate structure that can be selectively adjusted to reduce critical-dimension (CD) variations. In some embodiments, the method is performed by forming a gate structure having a first length over a semiconductor substrate. The first length of the gate structure is measured and compared to a target length. If the first length differs from the target length by an amount that is greater than a threshold value, the first length is adjusted to converge upon the target length. By selectively adjusting the length of the gate structure, critical-dimension (CD) variations can be reduced, thereby increasing yield and reducing cost.
