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.

摘要: In a process for a semiconductor typically represented by a vertical power MOSFET, etc. of repeating various fabrications in a state of a thin film wafer with the thickness of the wafer being 200 μm or less, it is a standard procedure of conducting processing in a stage of bonding a reinforcing glass sheet to a device surface of the wafer (main surface on the side of surface) in the step after film thickness-reduction. However according to the study of the present inventors, it has been found that about 70% for the manufacturing cost is concerned with the reinforcing glass sheet. In the present invention, a stress relief insulation film pattern is formed to the peripheral end of the rear face of a wafer in which processing to the device surface (surface side face) of the wafer has been completed substantially and back grinding has been applied.
