Abstract

The semiconductor device comprises a semiconductor substrate () with a main surface () and a further main surface () opposite the main surface, a TSV () penetrating the substrate from the main surface to the further main surface, a metallization () of the TSV, an under-bump metallization () and a bump contact () at least partially covering the TSV at the further main surface. The TSV () comprises a cavity (), which may be filled with a gas or liquid. An opening (') of the cavity is provided to expose the cavity to the environment.
