Warping of silicon wafers subjected to backgrinding process

This study investigates warping of silicon wafers in ultraprecision grindingbased backthinning process. By analyzing the interactions between the wafer and the vacuum chuck, together with the machining stress distributions in damage layer of ground wafer, the study establishes a mathematical model to describe wafer warping during the thinning process using the elasticity theory.
