A method includes the steps of: (a) fixing a front surface of a wafer (semiconductor wafer) having the front surface, a plurality of chip regions formed on the front surface, a dicing region formed between the chip regions, and a rear surface opposite to the front surface to the supporting member; (b) in a state of having the wafer fixed to the supporting member, grinding the rear surface of the wafer to expose the rear surface; (c) in a state of having the wafer fixed to the supporting member, dividing the wafer into the chip regions; (d) etching side surfaces of the chip regions to remove crushed layers formed in the step (c) on the side surfaces and obtain a plurality of semiconductor chips. After the steps (e) and (d), the plurality of divided chip regions are peeled off from the supporting member to obtain a plurality of semiconductor chips.
