  • Patent number: 11724352
    Abstract: A wafer processing method in which a wafer including devices on a front surface side is processed. The method includes a wafer-with-protective-component forming step of forming the wafer with a protective component through sticking the protective component formed of a resin that softens by heat to the front surface side by pressing and heating the protective component, a thickness measurement step of measuring a thickness of the protective component in the wafer with the protective component, and a grinding step of holding the wafer with the protective component by a chuck table and grinding a back surface side of the wafer until a thickness of the wafer becomes an intended finished thickness. In the grinding step, the thickness of the protective component measured in the thickness measurement step is subtracted from a total thickness of the wafer with the protective component to calculate the thickness of the wafer.
