With a 2000 gritgrinding process, the stress required to break the die was 50 percent higher than the stress needed to break a die with a (larger) 1200 gritgrinding process. Figure 2 shows the method of applying the test force to the die, and Figure 3 shows the difference in the scratches on the wafers using different grits to grind the silicon.
