1. A semiconductor device package comprising:

  • a circuit board having a plurality of electrical contact areas provided thereon and being provided with at least one component thereon for performing an electrical function;

    a semiconductor chip disposed in vertical registration with said circuit board and having an electrically active region thereon for performing electrical functions;

    a plurality of bonding pads provided at least in said electrically active region of said semiconductor chip, said bonding pads being in engagement with respective electrical contact areas on said circuit board for electrically connecting the electrically active region of said semiconductor chip to said circuit board;

    a lead frame having an inner lead frame portion disposed about the periphery of said circuit board and being in engagement with respective contact areas on said circuit board so as to be electrically connected to said circuit board and to said semiconductor chip via said circuit board, said lead frame including an outer lead frame portion comprising a plurality of conductive leads respectively connected at one end thereof to the inner lead frame portion and extending outwardly with respect to said circuit board and said semiconductor chip;

    resin means encapsulating said circuit board, said semiconductor chip, and the inner lead frame portion of said lead frame to provide a wireless hermetically sealed package; and

    said conductive leads of said outer lead frame portion being disposed outwardly of said encapsulating resin means.
