23.12.2020Generally, to effectively thin a wafer to its required thickness, a silicon wafer is ground in a brittle mode with a deeper cut prior to ductile-mode grinding, which inevitably induces SSCs in the wafer. Therefore, it is important to understand the formation mechanisms of SSCs to suppress their formation and propagation.
