Abstract
A semiconductor wafer has a front side, a rear side and an edge which runs along the circumference of the semiconductor wafer and which connects the front side and the rear side of the edge having a defined edge profile, the edge profile being substantially constant over the entire circumference of the semiconductor wafer. A method for producing such a wafer allows for production of a multiplicity of semiconductor wafers, the edge profile being substantially constant from semiconductor wafer to semiconductor wafer.
