Wafer Backgrind

November 20, 2017, anysilicon

Wafer backgriding is a process of thinning the wafer to meet the required thickness before packaging the die into its package. Wafer backgrinding is also called wafer thinning or wafer back-lapping. Backgrinding process is not a mandatory step in ASIC production, however, thinner semiconductor packages has made it unavoidable.
