A typical application for SEMs in the semiconductor industry consists of evaluating the critical dimensions (CDs) of the patterns typically printed on a silicon wafer. The path towards smaller and smaller structures and the introduction of new process materials require leading-edge metrology, thus challenging the capabilities of current generation tools and pushing the CD technique to its limits. Beyond this, the instrument should offer reliable data on target profile and shape with no decrease in usual quality parameters like resolution, precision and accuracy. We review the characteristics such an SEM should comply with in order to keep the pace with integrated-circuit technology, along with suitable solutions to improve metrological outputs.
