A semiconductor device has a semiconductor substrate, at least a first and
second rewiring device on a first surface of the semiconductor substrate
for the provision of an electrical contact-connection of the
semiconductor substrate, and a tapering, continuous opening from a first
surface to a second, opposite surface of the semiconductor substrate. At
least a third and fourth rewiring device is disposed on the second
surface of the semiconductor substrate and a patterned metallization on
the side areas of the opening for the separate contact-connection of the
first and at least the second rewiring device.
