Wafer Bow/Warp Optical Analyzer from Japan
A wafer bow/warp optical analyzer uses laser reflection to measure wafer bow, warp, and total thickness variation across 300mm semiconductor wafers. It is critical for stress analysis after deposition processes in semiconductor manufacturing. This optical measurement system falls under tariff item 9031.41.00 as it is designed for inspecting semiconductor wafers.

Import Tips
• Provide specifications showing the analyzer is designed for semiconductor wafers, not general flatness measurement
• The CBSA may require evidence of the laser reflection measurement method
• Verify if the system includes any data processing units that might affect classification
