Zusammenfassung:PROBLEM TO BE SOLVED: To provide a device of pasting a protective tape to a wafer so as to efficiently seal the peripheral end of the wafer, and to provide a method of manufacturing a wafer to which a protective tape is pasted.SOLUTION: A device of pasting a protective tape to a wafer includes a protective tape pasting section (d) for pasting a protective tape A, having an external diameter larger than that of a wafer W, to the rear surface of the wafer W so as to project from the peripheral end of the wafer W, and an end sealing section (i) for pasting a protective tape B, having an external diameter larger than that of the wafer W, to the surface of the wafer W to which the protective tape A is pasted in the protective tape A pasting section, so as to project from the peripheral end of the wafer W, integrating the peripheral end of the protective tape A and the peripheral end of the protective tape B, and sealing the peripheral end of the wafer W. 【課題】ウエハの周端部を効率よく封止することができるウエハへの保護テープの貼付装置および保護テープが貼付されたウエハの製造方法を提供する。【解決手段】ウエハWの外径よりも大きい外径を有する保護テープAを当該ウエハWの周端部から保護テープAが突出するようにウエハWの裏面に貼付するための保護テープAの貼り付け部dと、前記保護テープAの貼り付け部で保護テープAが貼付されたウエハWの表面に当該ウエハWの外径よりも大きい外径を有する保護テープBを当該ウエハWの周端部から突出させて貼付し、保護テープAの周端部と保護テープBの周端部とを一体化させ、ウエハWの周端部を封止するための端部封止部iを備えていることを特徴とする。【選択図】図2
