Leveraging blanket wafer film inspection to efficiently

This paper presents a methodology that uses unpatterned wafer inspection to detect material-related micro-masking defects in a tri-layer stack We investigated two approaches to detect the source of the micro-masking defect namely (i) defect source analysis (DSA) comparing patterned-wafer inspection results at post-develop and post-stack-etch and (ii) unpatterned-wafer inspection of
