wafer backgrinding quality

the silicon wafers used have a very high degree of flatness during manufacturing As part of the process of producing the wafers, the backside of these wafers is ground prior to dicing into the individual microchips, often as thin as 50 to 75 μm This conventional grinding step is referred to as wafer backgrinding and utilizes a diamond and
