Abstract
An electronic component has a first semiconductor chip and a second semiconductor chip that is arranged on a plastic compound in which the first semiconductor chip is embedded. The semiconductor chips are connected to one another by rewiring layers and vias which extend between the rewiring layers, the vias being widened at a transition to one of the rewiring layers.
Claims8
An electronic component, comprising:
- a first semiconductor chip embedded in a plastic compound;
- vias embedded in the plastic compound and extending through the electronic component from a first, upper rewiring layer to a second, lower rewiring layer, wherein the vias are widened at a transition to the second rewiring layer and include columnar portions that extend from the transitions at which the vias are widened toward the first, upper rewiring layer so as to form upper ends of the vias, each columnar portion having a substantially uniform cross-sectional dimension along the length of the columnar portion, the upper ends of the vias form a common plane with a corresponding upper end of the plastic compound, and the first, upper rewiring layer includes rewiring lines and contact pads and is disposed directly on the common plane defined by the upper ends of the vias and the upper end of the plastic compound;
- and
- a second semiconductor chip including semiconductor chip contacts, wherein the second semiconductor chip is in electrical contact with the first rewiring layer;
- wherein an active top side of the first semiconductor chip forms a common plane with a corresponding lower end of the plastic compound.
