Abstract:
According to an embodiment of a semiconductor substrate, the semiconductor substrate includes a superjunction structure in a device region of a semiconductor layer and an alignment mark in a kerf region of the semiconductor layer. The superjunction structure includes first regions and second regions of opposite conductivity types, the first and the second regions alternating along at least one horizontal direction. The alignment mark includes a vertical step formed by an alignment structure projecting or recessed from a main surface of the semiconductor layer. The alignment structure is of a material of the first regions of the superjunction structure.

Claim (Index 16):
The semiconductor substrate of  claim 1 , wherein the alignment structure is recessed below the main surface of the semiconductor layer, and wherein the vertical step is between the recessed alignment structure and a surrounding portion of the semiconductor layer.
