COMPONENT CARRIERS SANDWICHING A SACRIFICIAL STRUCTURE AND HAVING PURE DIELECTRIC LAYERS NEXT TO THE SACRIFICIAL STRUCTURE

摘要

A semifinished product (100) which comprises a sacrificial structure (102) and two component carriers (104) releasably formed on opposing main surfaces of the sacrificial structure (102), wherein each of the component carriers (104) comprises at least one electrically insulating layer structure (114), and at least one electrically conductive layer structure (116), and wherein the two electrically insulating layer structures (114), each of which relating to a respective one of the component carriers (104), located closest to the sacrificial structure (102) are pure or unprocessed electrically insulating layers without electrically conductive material therein.
