Consideration Of Missing Defect Suppression Technique In EUV Hole Patterning


This study focused on the defect behavior analysis with CD variation on EUV via hole pattern using photolithographic process and etch transfer performance. While defect requirements are not as stringent for memory devices, logic devices must be defect-free. Currently, a defect which comes from the process or material can only be detected by top-down inspection approach, however, it is difficult... » read more
