Abstract
CD measurements have been extracted from SEM and HRTEM images of the same set of monocrystalline silicon features having linewidths between 40 and 200 nm. The silicon features are incorporated into a new test structure which has been designed to facilitate this type of CD-metrology study. The purpose of the work was to evaluate the calibration statistics of SEM transfer-metrology when HRTEM is used as primary metrology.
