2018 11 29 2. WAFER THINNING PROCESS Si wafers are thinned in two stages backgrinding BG and stress relief Fig. 3 . During the grinding stage the two types of grinding are performed using wheels with different grit sizes. The grit size is generally described as # mesh and the larger the value the smaller is the grit size.

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.

2020 4 21 The back grinding process of the wafer is to put a layer of film on the front of the wafer to protect the integrated circuit that has been made and then use the grinding machine to reduce the thickness. After grinding and thinning the back of the wafer a damaged layer will be formed on the surface and the warpage is high which is easy to break.

The stock removal process removes a very thin layer of silicon and is necessary to produce a wafer surface that is damage free. On the other hand the final polish does not remove any material. During the stock removal process a haze forms on the surface of the wafer so an extra polishing step gives the wafer a mirror finish.
