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.

Claim (Index 15):
A method of manufacturing a semiconductor device, the method comprising:\n encapsulating a semiconductor device and a via with an encapsulant, wherein after the encapsulating the via is separated from the semiconductor device by the encapsulant; forming a redistribution layer over the via and the semiconductor device, the redistribution layer comprising a landing pad with a circular shape and a plurality of mesh openings within the landing pad, wherein the plurality of mesh openings are arranged in a circular pattern; forming a first passivation layer covering the plurality of mesh openings; removing portions of the first passivation layer to form an opening through the first passivation layer, wherein the removing the portions exposes a conductive portion of the landing pad that extends through a middle of the landing pad from a first side of the opening to a second side of the opening, the second side being the furthest from the first side; and forming an underbump metallization in physical contact with the exposed portion of the landing pad, the underbump metallization being over each of the plurality of mesh openings.
