Chemical Mechanical Planarization (CMP) Lapping Platform from Japan

CMP equipment using polishing pads and chemical slurries to planarize wafer surfaces during semiconductor fabrication. Though CMP-specific, classified under HTS 8460.40.80.80 as lapping/polishing machines for metal (silicon) finishing per statistical notes. Removes material layer-by-layer for multilayer chip construction.

Import Tips

Submit slurry composition analysis and removal rate data confirming material finishing function

Distinguish from Chapter 90 by emphasizing mechanical polishing over metrology capabilities
