Warping of silicon wafers subjected to back-grinding process ...

This study investigates warping of silicon wafers in ultra-precision grinding-based back-thinning 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.

The back-end process: Step 3 – Wafer backgrinding ...

For wafers with diameters of 200 mm, it is typical to start with a wafer thickness of roughly 720 µm and grind it to a thickness of 150 µm or less. The coarse grinding typically removes approximately 90 percent of the excess material. A typical two-step backgrinding operation will use dual spindles with grinding wheels mounted on each spindle.
