A semiconductor structure and the manufacturing method thereof are disclosed. An exemplary semiconductor structure includes a source/drain (S/D) feature formed in an interlayer dielectric layer (ILD), a S/D contact via electrically connected to the S/D feature, a metal feature formed over the S/D contact via, and a metal line formed over the metal feature and electrically connected to the S/D contact via. The metal line is formed of a material different from that of the S/D contact via, and the S/D contact via is spaced apart from the metal line. By providing the metal feature, electromigration between the metal line and the contact via may be advantageously reduced or substantially eliminated.
