The Takano WM-7SR wafer surface analyzer is being used to analyze unpatterned surfaces on wafers for particles. | The Takano WM-7SR wafer surface analyzer is being used to analyze unpatterned surfaces on wafers for particles. | ||
The instrument detects, counts and sizes defects on wafers with semiconductor substrate materials. The instrument uses a 405 nm laser beam which is scanning over the wafer surface to detect defect contamination, i.e. particles. When the laser beam hits a particle, it will scatter and be detected. | The instrument detects, counts and sizes defects on wafers with semiconductor substrate materials.
