  • Publication number: 20220146444
    Abstract: A method for measuring a resistivity of a silicon single crystal by a four-point probe method including: a first grinding step of grinding at a surface of the silicon single crystal on which the resistivity is measured; a cleaning step of cleaning the silicon single crystal subjected to the first grinding step; a donor-annihilation heat treatment step of heat-treating the silicon single crystal subjected to the cleaning step; and a second grinding step of grinding at least the surface of the silicon single crystal subjected to the donor-annihilation heat treatment step on which the resistivity is to be measured, where the resistivity of the silicon single crystal is measured by the four-point probe method after performing the second grinding step. This provides a method for measuring a resistivity of a silicon single crystal by which stable measurement is possible over a long period of time after a donor-annihilation heat treatment.
