SOI Wafer MEMS Engineering

In MEMS sensors, such as pressure sensor, sensitivity of the sensor is directly related to SOI membrane thickness. High variability of thickness will result in poor device properties. Our proprietary technology allows us to produce ultra uniform SOI wafers through layer transfer instead of grinding and polishing processes.

The back-end process: Step 3 Wafer 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.
