Silicon wafers after cutting have sharp edges, and they chip easily. Wafer edge is shaped to remove sharp, brittle edges; rounded edge minimizes risk for slipping, too. Edge shaping operation makes the wafer perfectly round (off-cut wafers are oval shaped after slicing), the diameter is adjusted, and orientation flat(s) or notch is dimensioned or made.
Feb 14, 2020· Silicon wafer is a semiconductor material used for the production of integrated circuits and other applications. It goes through several microfabrication processes, including edge grinding, to guarantee the quality of the wafers. In this article, we will discuss to you in detail the process of edge grinding. What is Edge Grinding?
Edge grinding, aka Edge Profiling, is critical to the manufacturing of all semiconductor wafers and wafers that are used in the manufacture of many other processes, such as Sapphire, Quartz, Alumina or Silicon Carbide. Edge grinding is critical to the safety and survivability of the wafer.

Newly-developed grinding unit enhances the rotative precision of the spindle, and improves the surface roughness. The non-contact measuring method achieves the stable alignment. Performs the non-contact measuring of the pre-processed wafer thickness at multiple points, the diameter and notch depth of the post-processed wafer.
Jun 03, 2011· Silicon wafers were first thinned by means of coarse mechanical grinding with a mesh size of approximately #325, followed by fine mechanical grinding with a mesh size of approximately #2000. When applying a high feed rate to achieve higher material removal rate during the coarse grinding process, the thinned silicon wafer with edge .
The edge grinding step is critical to the safety of the wafer edge. Silicon in this crystalline state is very brittle and if the edge is not profiled or rounded off, it will flake during handling and certainly during follow-on processing steps both mechanical in nature and thermally dynamic in nature.
"Edge trimming" effectively removes the rounded shap e on the outer edge of the wafer which causes edge chipping, preventing the wafer from breaking. In this review, we report the effects of edge trimming, which has been adopted for improving yield when performing ultra-thin wafer grinding. 1. Introduction During wafer ultra-thinning, the ...
