Abstract:
1. A method for manufacturing a microelectromechanical system package, comprising the steps of: providing a carrier with opposing first and second surfaces; forming a plurality of cavities on the first surface of the carrier, the each cavity having a central portion and a peripheral edge portion surrounding the central portion; forming a metal layer on the cavities and the first surface of the carrier; forming an isolation layer on the metal layer; forming a conductive trace layer on the isolation layer; electrically connecting a plurality of first microelectromechanical system chips to the conductive trace layer, the each first microelectromechanical system chip having an active surface, a back surface opposing to the active surface and an active area positioned on the active surface, wherein the active areas of the first microelectromechanical system chips are positioned corresponding to the cavities, respectively; and singulating the carrier to form individual microelectromechanical system packages, wherein the each microelectromechanical system package has at least one of the first microelectromechanical system chips.
