Abstract:
A first chip is mounted on a substrate and includes a plurality of bump pads located on an active surface of the first chip. A wire bonds a first bump pad to the substrate. An intermediate layer is disposed on a portion of the active surface of the first chip, and a via within the intermediate layer extends to a second bump pad. A second chip is disposed on the intermediate layer, and wherein the second chip includes a third bump pad located on an active surface of the second chip and aligned with the via formed in the intermediate layer. A corresponding bump is disposed on one or more of the second bump pad and the third bump pad, and within the via, wherein the corresponding bump electrically connects the second bump pad with the third bump pad.
