Abstract
A package includes a first redistribution structure, a die, a plurality of conductive structures, an encapsulant, and a second redistribution structure. The first redistribution structure includes a composite dielectric layer, a plurality of under bump metallization patterns, a dielectric layer, and a plurality of conductive patterns. The composite dielectric layer includes a first sub-layer and a second sub-layer stacked on the first sub-layer. The under bump metallization patterns are over the first sub-layer and penetrate through the composite dielectric layer. The dielectric layer is disposed on the second sub-layer of the composite dielectric layer. The conductive patterns are embedded in the dielectric layer. The die and the conductive structures are on the first redistribution structure. The encapsulant encapsulates the die and the conductive structures. The second redistribution structure is over the conductive structures, the encapsulant, and the die.
