Label for semiconductor wafer
 A semiconductor wafer label for identifying a wafer includes at least one concave mark formed on an edge of a flat zone of each wafer. The label may include one or more concave marks having a first width and first length and one or more concave marks having a second width and a second length. Accordingly, it is not necessary to take the wafer out of a wafer cassette in order to read the wafer number, thereby reducing contamination and damage to the wafer.
