Over 90% of semiconductors are built on silicon wafers. The fine grinding process has great potential to produce very flat wafers at a low cost. Four papers on fine grinding have been previously published by the authors. The first paper discussed its uniqueness and special requirements. The second one presented the results of a designed experimental investigation. The third and fourth papers presented mathematical models for the chuck shape and the grinding marks, respectively. As a follow up, this paper develops a mathematical model for the wafer shape. After the model is described, its practical applications in wafer manufactur-ing are discussed. (C) 2004 Elsevier Ltd.
