• Back Grinding Determines the Thickness of a Wafer

    2020 9 24 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.
