Stackable electronic package and method of fabricating same
An electronic package includes a first layer having a first surface, the first layer includes a first device having a first electrical node, and a first contact pad in electrical communication with the first electrical node and positioned within the first surface. The package includes a second layer having a second surface and a third surface, the second layer includes a first conductor positioned within the second surface and a second contact pad positioned within the third surface and in electrical communication with the first conductor. A first anisotropic conducting paste (ACP) is positioned between the first contact pad and the first conductor to electrically connect the first contact pad to the first conductor such that an electrical signal may pass therebetween.
1. A layer of a multi-layer electronic package, the layer comprising:
an electronic component comprising an active surface that includes first and second contact pads thereon;
a dielectric material having a first surface coupled to the active surface of the electronic component, the dielectric material including a plurality of vias therethrough;
an electrically conductive material having a first surface coupled to the first surface of the dielectric material;
metallization paths disposed on a second surface of the dielectric material and through the plurality of vias, each of the metallization paths electrically connecting a respective part of the electrically conductive material to a respective one of the first and second contact pads; and
feed-thru pads electrically coupled to the metallization paths.
2. The layer of claim 1 wherein a surface of the electronic component opposite the active surface and a surface of the electrically conductive material opposite the first surface thereof form portions of a bottom surface of the layer, and wherein the feed-thru pads form a portion of a top surface of the layer.
3. The layer of claim 1 further comprising an encapsulant positioned about the electronic component and the electrically conductive material.
4. The layer of claim 1 wherein the feed-thru pads comprise multi-layer structures.
5. The layer of claim 1 further comprising a mask layer applied to a second surface of the dielectric material and surrounding side surfaces of the feed-thru pads.
