Abstract:
1. An integrated circuit package, comprising: a two metal layer bumped circuit having a medial insulating layer and interconnection bumps on at least one side of an interconnection region of the circuit and being adapted for face-to-face interconnection to an integrated circuit die; a first adhesive lover having a thickness on a first side of the bumped circuit; a first outer conductive layer having a thickness bonded to the first adhesive layer; a second adhesive layer having a thickness substantially equal to the thickness of the first adhesive layer on a second side of the bumped circuit; and a second outer conductive layer bonded to the second adhesive layer, the second outer conductive layer having a thickness substantially equal to the thickness of the first outer conductive layer and relatively thick in relation to the medial insulating layer, wherein at least one of the first and second outer conductive layers has a window defined therethrough for receiving an integrated circuit die.
