Silicon Wafer Production

Grinding brings the slice into a rough thickness and flatness tolerance after which the lapping process removes the last bit of unwanted material from the slice faces, leaving a smooth, flat, unpolished surface. Lapping typically achieves tolerances of less than 2.5 µm uniformity in wafer surface flatness.
