Abstract:
A semifinished product with a sacrificial structure and two component carriers releasably formed on opposing main surfaces of the sacrificial structure. The sacrificial structure includes a central structure and releasing layers on or over both opposing main surfaces of the central structure The central structure includes a dummy core being covered, in particular fully, on or over both main surfaces thereof with a respective one of two spatially separated sections of separate material, in particular separate dielectric material.
