Abstract:
1. An integrated circuit (IC) package comprising: a first substrate including a first surface having first substrate bond pads, a second surface, and an opening that extends from the first surface to the second surface a first IC having a first IC surface that includes first bond pads and that is directly attached to the second surface of the first substrate, and a second IC surface, wherein the first bond pads are accessible through the opening; and a second IC having a third IC surface and a fourth IC surface, wherein the third IC surface is directly attached to the second IC surface, wherein at least one of the first bond pads is connected to at least one of the first substrate bond pads using one or more bond wires, wherein the opening has a first side and a second side, wherein the first substrate bond pads are located adjacent to only the first side of the opening, wherein the fourth IC surface includes second bond pads, wherein the second surface includes second substrate bond pads, and wherein at least one of the second bond pads is connected to at least one of the second substrate bond pads using one or more bond wires.
