Erlangen, Germany). During grinding, deionized (purified) water is being used to cool the grinding wheel and the wafer surface. Surface grinding can be used for grinding wire-sawn wafers, to replace or partially replace lapping. It can also be used for grinding etched wafers, to partially
Single crystal silicon wafers of 300 mm diameter with the (100) plane as the major surface are used for this investigation. To block the possible effects of the variations in surface quality of the test wafers, all the test wafers have been lapped with 7 μm Al 3 O 2 abrasive slurry, removing 50 μm from each side of the wafers.. Only one side of the wafers is ground and the grinding removal ...
