Abstract:
A wafer includes a first face having a first center, and a second face having a second center. The first and second centers are each arranged on a central axis, which passes through the first face and the second face. The first face and the second face adjoin one another at a circumferential edge. An alignment notch is disposed along the circumferential edge, and extends inwardly from the circumferential edge by an alignment notch radial distance. The alignment notch radial distance is less than a wafer radius as measured from the first center to the circumferential edge. A die region includes an array of die arranged in rows and columns and is circumferentially bounded by a die-less region which is devoid of die. A first identification mark including a string of characters is disposed entirely in the die-less region to a first side of the alignment notch.

Claim (Index 20):
A method, comprising:\n receiving a semiconductor wafer; forming a first identification mark on a frontside of the semiconductor wafer or on a layer over the frontside of the semiconductor wafer; forming at least one dielectric layer and at least one conductive layer over the semiconductor wafer and over the first identification mark; after the at least one dielectric layer and the at least one conductive layer have been formed, determining whether the first identification mark is readable; and selectively forming a second identification mark in or over the at least one dielectric layer and the at least one conductive layer, based on whether the first identification mark is readable.
