  • Patent number: 7863104
    Abstract: 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.

  • Patent number: 7708854
    Abstract: Explained, inter alia, is a method in which a workpiece (52) to be processed is fastened to a work carrier (10) by means of a solid (62). The work carrier (10) is made of a porous material, e.g. of porous ceramic. This processing method permits simple manipulation of the wafer during the processing. In addition, the workpiece (52) can be easily separated from the work carrier (10) using a solvent.
