For example, you want to grind a silicon wafer from 725 micrometers to 50 micrometers. The first stage will involve coarse grinding the wafer down to 100 micrometers using a machine. Next, you will need to further finely grind the wafer,

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. Silicon (Si) and Dicing Before Grinding (DBG) Process,,Dicing Before Grinding (DBG) of silicon wafers is frequently used for the manufacturing of memory devices with stacked thin die used in mobile devices. It is also adopted in the manufacturing of a wide range of semiconductor devices that need thinner die for the purpose of high-profile manufacturing, such as microcontrollers for mobile device and chips for IC cards.Silicon wafers manufacturing - Sil'tronix Silicon Technologies,Silicon wafer edge grinding. As the cutting process is creating sharp edge, a step for edge grinding is necessary to eliminate peripheral stress and scratches. At the end of this step, the final diameter is setted. Silicon wafer lapping. The wafers are putted on satellites for double side grinding. This step allows to eliminate the saw marks, improve the TTV (Total Thickness Variation) and,
