Silicon Wafer Back Grinding

Thin Silicon Wafers The Process of Back Grinding for

Backside Thinning (or Back Grinding) Wafer grinding or backgrounding is the most popular method for thinning wafers. The dimension to which a wafer can be thinned depends heavily on the machine used, but most thin silicon wafers have around
