Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of grinding a wafer where a grinding stone is not chipped even when grinding the wafer using the grinding stone of a high porosity.  <P>SOLUTION: The method of grinding the wafer grinds and removes a prescribed quantity of the wafer using a grinding wheel 33 equipped with a vitrified bond grinding stone which is obtained by connecting super abrasive with a vitrified bond and which is provided with countless pores, whose porosity is 75 to 95% by volume. The method comprises a first grinding process of grinding and removing the thickness of 0.5 to 0.95t, and a second grinding process of grinding and removing the thickness of 0.5 to 0.05t which remains without being ground and removed by the first grinding process in the case of setting a thickness of the wafer which has to be ground and removed to be (t). A feeding quantity per a unit time of grinding water to feed in a first grinding process is set to be smaller than that to feed in a second grinding process.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
