Provided is a semiconductor package apparatus having a redistribution layer. The apparatus includes at least one or more semiconductor chips, a packing part protecting the semiconductor chips, and a support part supporting the semiconductor chips. The apparatus also includes external terminals extending outside the packing part, redistribution layers installed between the semiconductor chips and the support part and including redistribution paths, first signal transmitting units, and second signal transmitting units. The first signal transmitting units transmitting electrical signals generated from the semiconductor chips to the redistribution paths of the redistribution layers, and the second signal transmitting units transmit the electrical signals from the redistribution paths to the external terminals. Therefore, a size and a thickness of the semiconductor package apparatus can be reduced, and processes can be simplified to improve productivity.

A semiconductor package having an ultra thin thickness and a method of manufacturing the same are provided. The ultra thin semiconductor package comprises a circuit board in which a through hole is formed. A semiconductor chip is located in the through hole and a connecting element electrically connects the circuit board and the semiconductor chip. An epoxy molding compound (EMC) covers the semiconductor chip and the connecting element and a supporter having a thermal expansion coefficient similar to the EMC is attached inside the through hole on a lower surface of the semiconductor chip. An external connecting terminal is attached to at least one side of the circuit board. Because of the inclusion of the supporter, warpage of the semiconductor package resulting from the curing of the EMC is prevented.
