A typical semiconductor wafer may have a starting thickness of 775 µm, but the amount of material removed varies by device type. For example, the thickest wafers are used for logic gates and are 100 µm thick. DRAM memory usually requires semiconductor wafers with a thickness of 50 µm instead. MEMS memory is typically around 30 µm thick.
