Abstract:
A semiconductor wafer is provided with a substrate having a semiconductor element formation layer, a lowermost metal layer formed on the semiconductor element formation layer and an uppermost layer formed on the lowermost metal layer, and the semiconductor wafer also has plural chip regions and an evaluation element region that is that is defined as a region between the plurality of chip regions and that has a cutaway region that is subjected to dicing when separating an individual chip and a remnant region that is not subjected to dicing when separating the chip, and a lowermost layer electrode pad and an uppermost layer electrode pad that are formed at the remnant region and at a pad region are configured by a combination of metals having a line width of less than or equal to a predetermined value.
