Rotational grinding of silicon wafers—sub-surface damage ...

Mar 25, 2004  The type, extent and distribution of the sub-surface damage vary with different grinding conditions. Wafers ground in ductile mode are bound to have a different kind of damage distribution in depth than those ground partially or completely in brittle fracture mode. The existence of two types of sub-surface damage was demonstrated.
