Grinding residual stresses of silicon wafers affect the performance of IC circuits. Based on the wafer rotation ultra-precision grinding machine, the residual stress distribution along grinding marks and ground surface layer depth of the ground wafers are investigated using Raman microspectroscopy. The results show that the ground wafer surfaces mainly …
Grinding marks are regard as a great obstacle to manufacture spherical and aspheric surfaces with higher surface quality, lower energy and wastage. The scallop-height was studied for optimizing the grinding parameters firstly to reduce its effect on grinding marks. Secondly, the expression of grinding points distribution was established to characterize the grinding marks …
