Semiconductor Thickness Measurement & Wafer Backgrinding - MTI Instruments

MEMS memory is typically around 30 µm thick. Backgrinding removes a precise amount of material to achieve the desired thickness, but it also causes damage to the wafer's surface. That's why polishing is also used. This description of the wafer backgrinding process is high-level, but the entire fabrication process is very tightly controlled.
