Abstract:
1. A multilayer circuit carrier, comprising: at least one semiconductor chip and/or at least one discrete component; at least one rewiring layer, the rewiring layer comprising rewiring structures and an insulation layer, wherein the rewiring structures comprise through contacts, continuous conductor tracks and/or continuous metal plates in said insulation layer of the rewiring layer, and the rewiring layer is connected to said at least one semiconductor chip and/or at least one discrete component; at least one insulation layer comprising passage structures; an external contact layer on an underside of the circuit carrier; external contact areas arranged at a predetermined pitch on said external contact layer; and an anchoring layer arranged between the rewiring layer and the insulation layer, the anchoring layer comprising anchor regions that fix a position of the passage structures, wherein the external contact areas are electrically connected to the rewiring structures via the passage structures and the anchor regions.
