Grinding - a process where a milling tool is used to grind material from the wafer to create the desired wafer thickness or surface finish. This is typically quicker than lapping but may not work with certain materials or very thin wafers. Etching - a process where chemicals are used to alter the surface finish of a wafer by "etching" the material.

Where a grinding pad is used on a revolving platen, it will always wear unevenly due to the difference in relative movement speed and pad area across the pad diameter, this means that the grinding effect on the sample will change during the process, reducing the accuracy of the sample and the uniformity. Lapping is a more gentle process as the ...
