Semiconductor Wafer Lapper from Japan
Electromechanical lapping machine with self-contained motor that uses loose abrasive slurry on cast iron plates to achieve sub-micron flatness on semiconductor wafer surfaces prior to polishing. Critical for bringing wafers within tight dimensional tolerances. HTS 8479.89.65.00 for wafer preparation equipment.

Import Tips
• Include flatness specification data (bow/warp <1μm) confirming semiconductor use
• Classify slurry pumps separately if modular to avoid integral machine valuation
• Certify lapping plates meet semiconductor contamination standards (ultra-pure cast iron)
