Abstract

A semiconductor device includes a die, a redistribution layer (RDL) structure including a first polymer layer, a second polymer layer and a UBM layer. The die is encapsulated by an encapsulant. The RDL structure is disposed over the encapsulant. The second polymer layer is disposed on the first polymer layer, wherein a transmittance of the second polymer layer is smaller than a transmittance of the first polymer layer. The UBM layer is disposed over and electrically connected to the RDL structure, wherein the UBM layer is disposed in the first polymer layer and the second polymer layer.
