Abstract
The present disclosure relates to an integrated chip that includes a substrate, a first metal line, and a hybrid metal line. The first metal line includes a first metal material and is within a first interlayer dielectric (ILD) layer over the substrate. The hybrid metal line is also within the first ILD layer. The hybrid metal line includes a pair of first metal segments that comprise the first metal material. The hybrid metal line further includes a second metal segment that comprises a second metal material that is different from the first metal material. The second metal segment is laterally between the pair of first metal segments.
