BACKSIDE WAFER TREATMENTS TO REDUCE DISTORTIONS AND OVERLAY ERRORS DURING WAFER CHUCKING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240113039 titled 'BACKSIDE WAFER TREATMENTS TO REDUCE DISTORTIONS AND OVERLAY ERRORS DURING WAFER CHUCKING

Simplified Explanation

The abstract describes methods, device structures, and wafer treatment chemistries related to backside wafer treatments to reduce distortions and overlay errors due to wafer deformation during wafer chucking. A backside layer is applied to the wafer prior to chucking, and the chemistry of the backside layer lowers the surface free energy of the wafer during chucking to eliminate or mitigate wafer deformation during wafer processing.

  • Backside layer applied to wafer prior to chucking
  • Chemistry of backside layer lowers surface free energy of wafer during chucking
  • Eliminates or mitigates wafer deformation during wafer processing
