Abstract:
A method and system for uniquely identifying each semiconductor device die from a wafer is provided. Identifying features are associated with device die bond pads. In one embodiment, one or more tab features are patterned and associated with each of one or more device die bond pads. These features can represent a code (e.g., binary or ternary) that uniquely identifies each device die on the wafer. Each tab feature can be the same shape or different shapes, depending upon the nature of coding desired. Alternatively, portions of the one or more device die bond pads can be omitted as a mechanism for providing coded information, rather than adding portions to the device die bond pads.
