WebThe inspection of structured and unstructured wafers during the entire manufacturing process is permitted by the optical inspection system MicroProf ® DI. FRT's automated defect inspection allows for maximum quality. Productivity can be increased as a result, and costs can be saved by avoiding the further processing of defective wafers. WebThe wafer surface inspection system LS series can detect defects on unpatterned wafers with a mirror-finished surface. Applied technology of laser scattering achieves high sensitivity and high throughput detection of small contaminants and various types of defects on wafer surfaces prior to patterning.
