发明名称 半導体装置の製造方法
摘要 To provide a method of manufacturing a semiconductor device including a step of attaching a surface protective tape onto the surface of a wafer which has completed the wafer process, a step of subjecting the back surface of the wafer to back grinding, and a step of attaching a peeling assist tape onto the surface protective tape while vacuum-adsorbing the back surface of the wafer to apply a tension to the assist tape, thereby separating the surface protective tape from the wafer, wherein a vacuum suction system has a peripheral suction system for the peripheral part of the wafer and an internal suction system for the internal region of the wafer.
