Silicon Wafer Lapping Stationary Turbine Blades from United States
Stationary blades in steam turbine-driven lappers that flatten silicon wafer surfaces to nanometer tolerances post-slicing. These blades guide lapping plates for ultimate flatness in semiconductor fabrication. They are classified under this tariff item as other stationary blades for steam turbines, not for repair or remanufacture.
