Wafer Thinning - Silicon Valley Microelectronics

Fine grinding with a 1200 to 2000 grit sand & poligrind fine grind. This typically removes ~30µm or less of material at ≤1μm/sec and provides the final finish on the wafers. A 1200 grit sand leaves a rough finish with visible grind marks, while 2000 grit sand is less rough, but some grind marks are still apparent.

Also, by using a BT100 wheel for rough grinding and a Poligrind (Photo 6), which uses ultra-fine abrasive, for fine grinding, it has become possible to implement a thinning process, using grinding only. This can be achieved not just for 8-inch wafers but also 300 mm wafers, which in many cases would require a stress relief process.

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 two-step backgrinding operation will use dual spindles with grinding wheels mounted on each spindle.
