The effects of edge trimming

The effects of edge trimming

grinding. The wafers were thinned and polished to their finished thicknesses to verify edge chipping. Fig. 7 shows the number of edge chippings. This graph confirms the correlation between the number of edge chippings and the extent of damage due to rough grinding. When the edge is trimmed for a finished thickness plus 100 µm or more, edge chipping can be prevented. The aforementioned results ...

For wafers with diameters of 200 mm, it is typical to start with a wafer thickness of roughly 720 µm and grind it to a thickness of 150 µm or less. The coarse grinding typically removes approximately 90 percent of the excess material. A typical twostep backgrinding operation will use dual spindles with grinding .

Silicon Wafer Lapping

Silicon Wafer Lapping

Lapping is a mechanical process in which a pad is used with polishing liquid to to remove excess silicon from a wafer substrate, often producing a dull grey, semireflective finish. Lapping reduces stress which can build up during the ingot slicing process, while also helping to remove defects on the wafer front and back sides. Pure Wafer maintains both single and double side lapping tools ...
