Abstract: Two grinding methods, parallel grinding and cross grinding, were applied to the horizontalaxistype rotary surface grinding of silicon and tungsten carbide. It was found that the cross grinding method results in better ground surface roughness than parallel grinding for the silicon wafer and that an isotropic ground surface topography is achieved for both silicon and tungsten carbide by cross grinding.
Under the priority of accuracy and grinding rigidity to design the key components of multiaxis linked parallel grinding system of aspheric surface, such as high speed grinding spindle, B axis grinding rotary table, clamps and center high adjusting system.

Grinding wheels for manufacturing of silicon wafers: A silicon wafer back grinding Grinding is an important process for manufacturing of silicon wafers. The demand for silicon wafers with better quality and lower price presents tremendous challenges for the grinding wheels used in the silicon .
dance with the rules of layout. A silicon wafer provides the basis of the integrated circuit. Wafers are processed using a grinding process that produces a flat surface that is still conductive at this stage. The wafer is insulated by growing a thermal oxide layer so that leakage of current between transistors is prevented. A conducting layer is
