In this work, important use cases for HV-SEM will be explored by simulation, such as HAR hole / trench imaging with various profiles and depths, buried feature imaging to understand detection and effective resolution with depth for optical overlay cases, and buried defect and void detection, using a new improved electron beam simulator which greatly extends utility of JMONSEL, AMAG SimuSEM, enabling many complex simulation scenarios to be achievable with many improved outputs and other augmentations. The use of simulation designed experiments (DOEs) to predict best conditions and performance for the above applications will be demonstrated, along with some physical validation in the HV-SEM process space for the JMONSEL/SimuSEM physics kernel by reproducing a few cases in the literature and to experimental results on recent AMAG7 HAR measurement targets.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
