  • Publication number: 20180218989
    Abstract: A redistribution layer with a landing pad is formed over a substrate with one or more mesh holes extending through the landing pad. The mesh holes may be arranged in a circular shape, and a passivation layer may be formed over the landing pad and the mesh holes. An opening is formed through the passivation layer and an underbump metallization is formed in contact with an exposed portion of the landing pad and extends over the mesh holes. By utilizing the mesh holes, sidewall delamination and peeling that might otherwise occur may be reduced or eliminated.
