Buy Silicon Wafer The Process of Edge Grinding Silicon

This process is carried out using a profiled diamond wheel, and the edge profile pursues the shape provided by SEMI M10307. Usually, the SEMI standard profile is not suitable for MEMS appliion, especially if the wafers still need to be thinned after processing. The asymmetric edge profile is more ideal for this. Why is Edge Grinding Done?

The thinning of wafers is called grinding. As a rule, the grinding process takes place in several steps, each with a finer grain of the grinding wheels. On the one hand, this serves to optimize the process duration and, on the other hand, to reduce the damage to the crystal caused by grinding in the crystal.
