Wafer Backgrinding And Semiconductor Thickness

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 highdensity ic packaging.

Wafer Backgrind

Wafer Backgrind

Wafer backgrind wafer backgrind is the process of grinding the backside of the wafer to the correct wafer thickness prior to assembly. it is also referred to as wafer thinning. wafer backgrinding has not always been necessary, but the drive to make packages thinner and thinner has made it indispensable.

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. ifafer becomes even thinner, external defects occur during the sawing process. for this reason, if the thickness ofafer is 50 or less, the process order can be changed.
