Investigation of precision grinding process for production

Investigation of precision grinding process for production

The appliion of precision grinding for the formation of a silicon diaphragm is investigated. The test structures involved 26 mm diam diaphragms with thicknesses in the range of 25150 μm. When grinding is performed without supporting the diaphragm, bending occurs due to nonuniform removal of the silicon material over the diaphragm region.

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?

With a 2000 grit grinding process, the stress required to break the die was 50 percent higher than the stress needed to break a die with a (larger) 1200 grit grinding process. Figure 2 shows the method of applying the test force to the die, and Figure 3 shows the difference in the scratches on the wafers using different grits to grind the silicon.
