The 1997 National Technology Roadmap for Semiconductors (NTRS) and the 1999 International Technology Roadmap for Semiconductors (ITRS) include chapters outlining metrology needs for the silicon semiconductor industry during the next five years and beyond1. The grand challenges include affordable scaling, new materials and structures, and yield and reliability. Although additional requirements within these categories are detailed, it is often difficult for the analytical specialist or metrology equipment vendor to translate these grand challenges into detailed and meaningful roadmaps for success in analytical applications or instrument development. The path-to-impact of a single metrology activity is not always clear.
