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.

What is a Silicon Wafer? Silicon Valley Microelectronics
During the stock removal process, a haze forms on the surface of the wafer, so an extra polishing step gives the wafer a mirror finish. After polishing, the silicon wafers proceed to a final cleaning stage that uses a long series of clean baths. This process removes surface particles, trace metals, and residues.
