发明名称 Method of producing a thin semiconductor chip
摘要 A method of fabricating a semiconductor chip includes the providing an adhesive layer on the outer area of the active surface of a device wafer and attaching a rigid body to the active surface by the adhesive layer. The device wafer is thinned by treating the passive surface of the device wafer. A first backing tape is connected to the passive surface of the device wafer. The outer portion of the rigid body is separated from the central portion of the rigid body and the outer portion of the device wafer is separated from the central portion of the device wafer. The central portion of the rigid body, the outer portion of the device wafer and the outer portion of the rigid body are removed from the first backing tape. The device wafer may be diced into semiconductor chips.
