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

    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. Scratches and Wafer Strength After backgrinding, the wafer will exhibit a scratch pattern on the backside (Figure 1a).
