In a semiconductor wafer that has semiconductor devices arranged in a plurality of device-formation-regions and a TEG placed in dividing regions that define the device-formation-regions, a TEG-placement portion is arranged in the dividing regions partially expanded in width, and the TEG is placed in the TEG-placement portion. Additionally, a protective sheet is stuck to the semiconductor wafer, then plasma etching is performed, and the TEG is removed in a state where it remains in the dividing region and stuck to the protective sheet together with the protective sheet by peeling off the protective sheet, thereby the device-formation-regions are divided into individual pieces, and the semiconductor chips are manufactured.
