description A silicon wafer single-side polishing method that can significantly improve the stepped minute defect occurrence rate is provided. The silicon wafer single-side polishing method comprises: a first polishing step of performing polishing on one side of a silicon wafer under a first polishing condition; and a second polishing step of performing polishing on the silicon wafer under a second polishing condition in which at least one of an applied pressure and a relative speed in the first polishing condition is changed, after the first polishing step, wherein a polishing rate ratio according to the first polishing condition is higher than a polishing rate ratio according to the second polishing condition.
