  • Grinding of silicon wafers: A review from historical

    Using an in-feed grinder (a SSG machine) for flattening of substrate wafers, it takes two operations to grind both sides of the wafer, one side per operation. It would be more economical if both sides of the wafer could be ground simultaneously. This motivated the development of SDSG for flattening of substrate wafers [45–47].
