Feb 01, 2007018332Raman spectra of wafer surfaces ground by the 325 a, 600 b, and 2000 u grinding wheels. presence of the Si-III and Si-XII confirms that the Si momentarily exists in the metallic phase Si-II because the transformation from Si-I to Si-IBSi-XII a-Si is possible only by first transforming into me- Zhang Y.X. et al., Microstructure.
The fine-grained microstructure was characterised by extensive lateral cracks in the grinding process and widespread grain pullout during the mechanical polishing in contrast, the large elongated.
The objective of this study is to design and evaluate soft abrasive wheels for silicon wafer grinding. In this study, CeO2, SiO2, Fe2O3 and MgO soft abrasives are used in the design of soft.

Very even tex ture is usually made by two grinding oper173 at ions. The first reduces the peanuts to a med ium grind and the second to a fine smooth texture. The purpose of the present study is to compare the effects of three different grinding procedures on the microstructure of quotold.
The number, location and orientation of the samples examined are important parameters in sample selection. Sectioning, grinding and polishing are used to prepare a flat specimen with a mirror like finish. Care must be taken during sample preparation not to introduce artifacts which lead to invalid microstructure interpretations.

May 01, 2018018332The grinding wheel used in this study was a coarse-grained electroplated diamond grinding wheel with the abrasive grain size of 213 181m, the diameter of 75 mm, and the wheel width of 3 mm. The grinding wheel was conditioned by a vitrified diamond wheel with the method, as shown in Fig. 1, and the conditioning parameters are listed in Table 2.
Dec 15, 2016018332And it could control the subsurface damage depth using the fine grinding wheel and reducing the grinding depth. The relationship between surface roughness and subsurface damage was analyzed based on the indentation theory, which found that the simulation results were close to the experiment results when the value of m is in the range of 1814.
