WebAug 19, 2024 · In a dark-field inspection method using EUV beam as inspection light, even if no defect is present, inspection signal may be obtained from a certain background level. This is due to surface roughness on the multilayer reflective film. The smaller the roughness, the lower the background level. http://www.nanolab.t.u-tokyo.ac.jp/pdffiles/PSI637508-usuki.pdf
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 optical inspection of patterned wafers can employ bright-field illumination, dark-field illumination, or a combination of both for defect detection. Patterned wafer inspection systems compare the image of a …
