Abstract (en)

[origin: WO2011095189A1] The invention relates to a method for treating a product wafer temporarily bonded to a carrier wafer, comprising the following steps: grinding and/or back-thinning the product wafer on a flat side facing away from the carrier wafer to a product wafer thickness D of < 150 µm, in particular < 100 µm, preferably < 75 µm, more preferably < 50 µm, especially preferably < 30 µm, and after the grinding and/or back-thinning, treating the surface of the flat side using means for reducing an, in particular structural, internal stress of the product wafer.
