Semiconductor Wafer Lapper from Mexico

Semiconductor wafer lappers use abrasive slurries with temperature-controlled slurries to lap both sides of silicon wafers simultaneously, achieving critical flatness for device fabrication. Part of wafer preparation equipment in statistical note (a)(ii)(C). HTS 8419.89.95 covers the temperature-regulated lapping process.
