Abstract:
1. A method for manufacturing a package structure having a micro-electromechanical element, comprising: preparing a carrier board having a first surface and a second surface opposing the first surface; providing a plurality of micro-electromechanical elements on the first surface of the carrier board, each of the micro-electromechanical elements having a plurality of electrical contacts; connecting the electrical contacts and the first surface of the carrier board by a plurality of bonding wires; forming a package layer on the first surface of the carrier board to enclose the micro-electromechanical element, the electrical contacts, and the bonding wires; removing the carrier board to expose one end of each of the bonding wires; and forming a build-up layer structure on the surface of the package layer that exposes the bonding wires, the build-up layer including at least one dielectric layer and a plurality of conductive blind vias formed in the dielectric layer and electrically connected to one ends of the bonding wires.
