Surface Integrity Control During The Precision ..

2006 3 29 In this example a 50 mm diameter BK7 testpiece was ground on a 5 axis Edgetek grinding machine using a resin bond diamond grinding wheel. The workpiece was rotated at 5.5 rpm and the grinding wheel traversed from the outer edge to the centre. Thus the chip thickness varied from a maximum value at the outer edge to a minimum value at the centre.

Back Grinding Determines the Thickness of a Wafer

2020 9 24 Back grinding is a step of grinding the back of a wafer thinly. This isn't just simply about reducing the thickness of a wafer this connects the front end process and the back end process to solve problems that occur between the two processes. The thinner semiconductor chips are the higher the integration can be through higher chip stacking.
