The wafer grinding by use of fixed abrasive diamond wheels is required to create a high-quality wafer surface in a short time. In general, it is known that the grinding performance of diamond wheel is mainly dependent on grinding wheel specifications and grinding conditions. The cutting edge distribution or abrasive protrusion height in depth-wise of a specified wheel is one of the most ...

Grinding marks on silicon wafers are caused by the axial run out of the cup wheel. Grinding marks present multiple angular wavelengths characteristics. A grinding marks formation model was developed. An angular wavelength model of the grinding marks was developed. Grinding marks can be suppressed by reducing the cutting paths aggregation.

Routine measurement of interstitial oxygen in silicon wafers utilizes infrared absorption at 1107 cm-1 (9.03 µm). This is the absorption band associated with anti-symmetric vibration of SiO2 in the silicon lattice. (7) The infrared beam passes through a wafer sample from the front to the back (Figure 2).
