Thin wafer thickness

WebDRAM memory usually requires semiconductor wafers with a thickness of 50 µm instead. 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.
