A semiconductor wafer, a panel, and an electronic component, and also
methods for producing them is disclosed. In this context, the electronic
component has a stack of two semiconductor chips. The top stacked
semiconductor chip is thin-ground and is arranged using flip-chip
technology on a central region of the bottom semiconductor chip. An edge
region of the bottom semiconductor chip contains vias through a leveling
layer to a rewiring plane, which for its part carries external contacts.
