  • Patent number: 10825728
    Abstract: A method is provided for producing at least one electrical via in a substrate, the method comprising: producing a protective layer over a component structure which has been produced or is present on a front side of the substrate; forming at least one contact hole which extends from a surface of a backside of the substrate to a contact surface of the component structure; forming a metal-containing and thus conductive lining in the at least one contact hole creating a hollow electrically conductive structure in the at least one contact hole; and applying a passivation layer over the backside of the substrate, the passivation layer spanning over the hollow electrically conductive structure for forming the at least one electrical via. Also provided is a micro-technical component comprising at least one electrical via.
    Type: Grant
    Filed: December 17, 2018
    Date of Patent: November 3, 2020
    Assignee: X-FAB Semiconductor Foundries GmbH
