Patent ID: 7423338

Claim:
A base having a surface for carrying a first integrated circuit die having a plurality of flip-chip bumps on a front-side surface and having a back-side surface and a second integrated circuit die having a plurality of bond pads on a front-side surface and having a back-side surface, the base comprising: a base having multiple layers of interconnected circuitry formed at different levels therein, the interconnected circuitry for connecting circuits of the first integrated circuit die to the same circuits of the second integrated circuit die; a first plurality of flip-chip pads arranged in a first pattern on the surface of the base, the first plurality of flip-chip pads connecting at least one flip-chip bump of the plurality of flip-chip bumps on the front-side surface of the first integrated circuit die carried on the surface of the base; and a second plurality of wire-bondable pads connected to the first plurality of flip-chip pads and arranged in a pattern on the surface of the base, the second plurality of wire-bondable pads connected to at least one bond pad of the plurality of bond pads on the front-side surface of the second integrated circuit die carried on the back-side surface of the first integrated circuit die.
