Back Grinding Determines the Thickness of a Wafer SK

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

Wafer Backgrinding and Semiconductor Thickness

Wafer backgrinding is the first step in semiconductor packaging, the process of encasing one or more discrete semiconductor devices or integrated circuits (IC) for protection. Known also as wafer thinning or wafer lapping, backgrinding reduces wafer thickness to allow stacking and high-density IC packaging.
