  • Patent number: 12100644
    Abstract: An intermetal dielectric and metal layers embedded in the intermetal dielectric are arranged on a substrate of semiconductor material. A via hole is formed in the substrate, and a metallization contacting a contact area of one of the metal layers is applied in the via hole. The metallization, the metal layer comprising the contact area and the intermetal dielectric are partially removed at the bottom of the via hole in order to form a hole penetrating the intermetal dielectric and extending the via hole. A continuous passivation is arranged on sidewalls within the via hole and the hole, and the metallization contacts the contact area around the hole. Thus the presence of a thin membrane of layers, which is usually formed at the bottom of a hollow through-substrate via, is avoided.
