Webmetrology specifications are evolving in recognition of this. As the linewidth variation is the determining factor of roughness effect on product, the ITRS now specifies LWR over a window of spatial frequencies. Previous versions specified LER with no frequency window. The 2003 roadmap requires that the LWR litho control, the amount of WebAfter litho metrology was measured using optical imaging metrology, as well as after etch metrology using both SE and CD-SEM for comparison. We investigate 2 types of machine learning techniques with SE data: model-less and model-based, showing excellent performance for after etch in-cell on-device overlay metrology. Publication:
