Back Grinding Determines the Thickness of a Wafer | SK ...

When the wafer is thick, super fine grinding can be performed, but the thinner the wafer is, the more necessary the grinding is to be carried out. If a wafer becomes even thinner, external defects occur during the sawing process. For this reason, if the thickness of a wafer is 50㎛ or less, the process order can be changed.
