Silicon Carbide Grinding and Cut-Off Wheels. 107 products. Grinding wheels and cut-off wheels are covered in abrasive grit and used for grinding, cutting, and machining applications. Grinding wheels remove material from metal, glass, wood, brick, or concrete. Cut-off wheels cut or notch these surfaces.

Semiconductor Back-Grinding

The backgrinding process involves using a diamond-resin bonded grinding wheel to remove the silicon material from the back of a silicon wafer. Using a grinding wheel is highly effective, and faster and less expensive than chemical-mechanical processes and is used to remove the bulk of substrate material prior to final finish grind, polish or ...

Wafer Backgrinding | Silicon Wafer Thinning | Wafer Backgrind

Oct 22, 2019· The Process. The process of thinning wafers involves using a mechanical grinding wheel, chemical slurry, and IR equipment- to help you measure the thickness. A classic grinding process would involve three stages: coarse grinding, fine grinding, and polishing. For example, you want to grind a silicon wafer from 725 micrometers to 50 micrometers.

Wafer backgrinding - Wikipedia

The stock removal process removes a very thin layer of silicon and is necessary to produce a wafer surface that is damage-free. On the other hand, the final polish does not remove any material. During the stock removal process, a haze forms on the surface of the wafer, so an extra polishing step gives the wafer a mirror finish.
