The interconnect structure includes a landing pad region and a dummy region electrically separated from each other. A protective layer overlies the interconnect structure and includes a first opening exposing a portion of the landing pad region and a second opening exposing a portion of the dummy region. A metal layer is formed on the exposed portion of landing pad region and the exposed portion of the dummy region.
