Silicon (Si) and Dicing Before Grinding (DBG) Process
In the DGB process, die separation is performed by grinding (processing using a grinding wheel), not by dicing (cutting using a blade). The DGB process does not require full-cut dicing or die separation using a blade, so the risk of backside chipping is greatly reduced. Improvement in Die Strength

This removal is typically done by a grinding process and is known as back side grinding, although it can be anticipated that other methods than grinding might be used. In one method, a protection tape is placed on the top side of the wafer to protect the circuitry, and the back side is thinned by grinding.

Wafer dicing Wikipedia
The DBG or "dice before grind" process is a way to separate dies without dicing. The separation occurs during the wafer thinning step. The wafers are initially diced using a half-cut dicer to a depth below the final target thickness. Next, the wafer is thinned to the target thickness while mounted on a special adhesive film and then mounted on to a pick-up tape to hold the dies in place until they are ready for the packaging step. The benefit to the DBG process is higher die strength. Alternatively, plasma dicing ma

Wafer backgrinding Wikipedia
Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and high-density packaging of integrated circuits (IC). ICs are produced on semiconductor wafers that undergo a multitude of processing steps. The silicon wafers predominantly used today have diameters of 200 and 300 mm. They are roughly 750 μm thick to ensure a minimum of mechanical stability and to avoid warping during high-temperature processing steps.
