WebHands-on experience in lithographic wafer patterning steps in fab or with simulation modeling. A very good understanding of optics and material physics is strongly desired. Experience in advanced technology nodes for DUV and EUV is a strong plus. Experience with hands-on metrology data collection on SEM Metrology tool is a plus. WebAbstract. A vast number of defect mechanisms arise in any modern VLSI fabrication process. Defects associated with the starting wafer and with lithography steps (i.e. resist-level patterns) are common to virtually all fabrication processes. Wafer defects are considered in Section 3.1 while lithography defects are discussed in Section 3.2.
