Abstract:
An IC die and a flexible circuit structure are integrated into a lower stack element that can be stacked with either further integrated lower stack element iterations or with pre-packaged ICs in any of a variety of package types. The present invention may be employed to stack similar or dissimilar integrated circuits and may be used to create modularized systems. In a preferred embodiment, a die is positioned above the surface of portions of a pair of flex circuits. Connection is made between the die and the flex circuitry. A protective layer such as a molded plastic, for example, is formed to protect the flex-connected die and its connection to the flex. Connective elements are placed along the flex circuitry to create an array of module contacts along the second side of the flex circuitry. The flex circuitry is positioned above the body-protected die to create an integrated lower stack element. The integrated lower stack element may be stacked either with iterations of the integrated lower stack element or with a pre-packaged IC to create a multi-element stacked circuit module.

Abstract:
Flexible circuitry is populated with integrated circuitry disposed along one or both of its major sides. Contacts distributed along the flexible circuitry provide connection between the module and an application environment. The circuit-populated flexible circuitry is disposed about an edge of a rigid substrate thus placing the integrated circuitry on one or both sides of the substrate with one or two layers of integrated circuitry on one or both sides of the substrate. The substrate form is preferably devised from thermally conductive materials and includes a high thermal conductivity core or area that is disposed proximal to higher thermal energy devices such as an AMB when the flex circuit is brought about the substrate. Other variations include thermally-conductive clips that grasp respective ICs on opposite sides of the module to further shunt heat from the ICs. Preferred extensions from the substrate body or substrate core encourage reduced thermal variations amongst the integrated circuits of the module.

A region of the second face of the substrate, which overlaps the first region in plan view, is formed to be a smooth face.
