Flexible routing for high current module application

摘要

In one aspect of the invention, an integrated circuit package is described. The integrated circuit package includes a substrate formed from a dielectric material that includes multiple electrical contacts and conductive paths. An upper lead frame is attached with and underlies the substrate. The upper lead frame is electrically connected with at least one of the contacts on the substrate. The active surface of an integrated circuit die is electrically and physically coupled to the upper lead frame through multiple electrical connectors. A lower lead frame may be attached with the back surface of the integrated circuit die. A passive device is positioned on and electrically connected with one of the contacts on the substrate and/or the upper lead frame.
