A method of manufacturing a semiconductor element is provided. The method includes the following steps. A carrier and a mold are provided. A first patterned conductive layer including a plurality of traces is formed on the carrier. A second patterned conductive layer is formed on the first patterned conductive layer. The carrier is disposed with the mold to form at least one mold cavity. The mold cavity is infused with a molding material. The molding material fills the mold cavity to encapsulate the first and second patterned conductive layers. The carrier is removed by etching to expose the plurality of traces embedded in the molding material without affecting the width of the traces.

Method of manufacturing semiconductor element

A semiconductor package and a manufacturing method thereof are provided. The package element has a first insulating layer, and a plurality of holes are disposed on the first surface of the first insulating layer. Besides, a plurality of package traces are embedded in the insulating layer and connected to the other end of the holes. The holes function as a positioning setting for connecting the solder balls to the package traces, such that the signal of the semiconductor chip is connected to the package trace via conductor of the chip, and further transmitted externally via solder ball. The elastic modulus of the material of the first insulating layer is preferably larger than 1.0 GPa.
