Abstract:
A thermally enhanced IC chip package comprising:a dielectric substrate member having top and bottom surfaces with conductive circuit patterns, and an opening therethrough; a plurality of solder balls being electrically connected to said bottom surface of said substrate member; an IC chip having an active side and an inactive side, said chip being received in said opening of said substrate in such a way that said active side of said chip and said top surface of said substrate face to a same direction, said active side electrically connected with said top surface of said substrate; a thermally and electrically conductive adhesive layer disposed on said inactive side of said chip and on said bottom surface of said substrate in a completely enclosing shape around said opening; a thermally and electrically conductive planar member having top and bottom surfaces, said planar member being attached to said thermally and electrically conductive adhesive layer with said top surface thereof; and a molding material encapsulating said chip, said opening and said top surface of said substrate.
