Application Summary AI generated

This standard specifies an automated non-contact scanning method for measuring the warp of silicon wafers, which is the deviation of the wafer's median surface from a reference plane. It is applied in the semiconductor manufacturing industry for quality control and process monitoring of polished or epitaxial silicon wafers used in integrated circuit fabrication. The method ensures accurate, repeatable warp measurements without physically contacting the wafer surface, preventing damage during testing.
