Abstract:
1. An electronic device having a stack of semiconductor chips, the electronic device comprising: a first semiconductor chip and at least one semiconductor stack chip stacked onto the first semiconductor chip, the semiconductor chips each having an active upper side with contact areas; a rewiring plane arranged between the semiconductor chips and having a continuous first bonding hole; first contact regions in the vicinity of the first bonding hole; second contact regions which are connected to first contact regions of the rewiring plane; a rewiring substrate having external contacts of the electronic device on a lower side of the rewiring substrate and having a second continuous bonding hole; contact-terminal areas on an upper side of the rewiring substrate; bonding fingers on the lower side of the rewiring substrate, in the vicinity of the second bonding hole; a package which has a plastic packaging composition; and contact areas of the first semiconductor chip being connected by bonding connections through the second bonding hole of the rewiring substrate to bonding fingers of the rewiring substrate, and first contact regions on a lower side of the rewiring plane being connected through the first bonding hole of the rewiring plane to contact areas of the semiconductor stack chip and second contact regions of the rewiring plane being connected to contact-terminal areas of the rewiring substrate by stack connections.
