Abstract

In some examples, an electronic package and methods for forming the electronic package are described. The electronic package can be formed by disposing an interposer on a surface of a substrate having a first pitch wiring density. The interposer can have a second pitch wiring density different from the first pitch wiring density. A layer of non-conductive film can be situated between the interposer and the surface of the substrate. A planarization process can be performed on a surface of the substrate. A solder resist patterning can be performed on the planarized surface the substrate. A solder reflow and coining process can be performed to form a layer of solder bumps on top of the planarized surface of the substrate. The interposer can provide bridge connection between at least two die disposed above the substrate. Solder bumps under the interposer electrically connect the substrate and the interposer.
