| Zusammenfassung: | A semiconductor workpiece includes a semiconductor substrate, at least two chip areas, components of semiconductor devices being formed in the semiconductor substrate in the at least two chip areas, and a separation trench disposed between adjacent chip areas. The separation trench is formed in a first main surface of the semiconductor substrate and extends from the first main surface to a second main surface of the semiconductor substrate. The second main surface is disposed opposite to the first main surface. The separation trench is filled with at least one sacrificial material. |
