Embodiments of present invention provide a method. The method includes forming a set of metal pillars on a substrate; forming a negative-tone organic dielectric layer covering the set of metal pillars; planarizing the negative-tone organic dielectric layer to expose the set of metal pillars; forming a resist mask on the negative-tone organic dielectric layer, the resist mask having openings that expose the set of metal pillars; and forming a redistribution layer in the openings of the resist mask, the redistribution layer being in direct contact with the set of metal pillars. A structure formed thereby is also provided.
