  • Patent number: 8129826
    Abstract: 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.
