A semiconductor package device includes a flexible carrier, a first chip, a second chip, a first molding layer, a first adhesive layer and a second molding layer. The flexible carrier has a flexible layer and a rigid layer. The flexible layer has a patterned build-up circuit. The rigid layer is connected to a portion surface of the flexible layer. The position that the flexible layer connected to the rigid layer is formed a first carrying part and a second carrying part. The region of the flexible layer between the first carrying part and the second carrying part without the rigid layer is formed as a first flexible part. The first chip is connected to the first carrying part by flip-chip manner and the second chip is connected to the second carrying part by flip-chip manner. The first molding layer covers the first chip and the second molding layer covers the second chip. The first adhesive layer is connected between the first molding layer and the second carrying part.
