Patent ID: 6838768

Claim:
A semiconductor assembly having a semiconductor device mounted on a first substrate and at least one semiconductor device mounted on a second substrate, said assembly comprising: a plurality of first substrates, each first substrate of the plurality of first substrates having a first side, a second side, an aperture therethrough, a plurality of circuits located on the first side and on the second side thereof, and a plurality of connection areas on the first side thereof; a plurality of semiconductor devices, each semiconductor device of the plurality of semiconductor devices having an active surface and a plurality of bond pads thereon, at least a portion of the active surface of each semiconductor device secured to the first side of a first substrate of the plurality of first substrates, at least one wire extending through the aperture in the first substrate and connected to a portion of at least one circuit of the plurality of circuits on the second side of the first substrate and at least one bond pad of the plurality on the active surface of a semiconductor device of the plurality of semiconductor devices; a second substrate having a first side, having a second side, and having portions of a plurality of circuits on the first side, a portion of at least one of the plurality of circuits connected to a portion of at least one circuit of the plurality of circuits on the second side of at least one first substrate of the plurality of first substrates; at least one connection between the at least one circuit on the first substrate of the plurality of first substrates and one of the plurality of circuits of the second substrate; a bus bar having a first side, a second side, and at least one circuit thereon; and a connection between one of the plurality of connection areas on the first side of the first substrate of the plurality of first substrates and the at least one circuit on the bus bar.
