Wafer grinding is potentially a more cost-effective process than lapping for flattening wire-sawn silicon wafers. Its success in replacing lapping, however, will depend on whether wire-sawing induced waviness can be effectively removed. FEA modeling has been used to investigate grinding and lapping of wire-sawn silicon wafers.
