Abstract:
A chip assembly may comprise a substrate having a top surface and a bottom surface. The chip assembly may comprise a first die having a circuit surface and a connecting surface, the circuit surface comprising one or more integrated circuits. The chip assembly may comprise a chip-scale frame having an inside surface, an outside surface, and a well region, the well region having an opening within the inside surface, the well region having a wall, the well region housing the first die, the first die attached to the wall by a first coupling mechanism, the inside surface coupled to the top surface of the substrate by a second coupling mechanism. The chip assembly may comprise a heat sink coupled to the outside surface of the chip-scale frame using a third coupling mechanism.
