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

24.09.2020  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. In this case, a Dicing before Grinding
