• The back-end process Step 3Wafer backgrinding

    With a 2000 grit grinding process the stress required to break the die was 50 percent higher than the stress needed to break a die with a (larger) 1200 grit grinding 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.
