Patent ID: RE44986

Claim:
A method for polishing a semiconductor wafer having a front side and a rear side, comprising: polishing the rear side of the semiconductor wafer by means of CMP with a material removal with a profile along the diameter of the semiconductor wafer according to which material removal is higher in a center region of the rear side than in an edge region of the rear side , wherein the material removal is 0.2 to 0.8 μm in the center region of the rear side and is 0.02 to 0.2 μm lower in the edge region of the rear side ; and polishing the front side of the semiconductor wafer by means of CMP with a material removal with a profile along the diameter of the semiconductor wafer according to which material removal is lower in a center region of the front side than in an edge region of the front side , wherein the material removal is 0.2 to 0.8 μm in the center region of the front side and is 0.02 to 0.2 μm higher in the edge region of the frontside; and polishing the semiconductor wafer by means of DSP, wherein the DSP is carried out before polishing the rear side of the semiconductor wafer by means of CMP .
