Abstract

Standards organizations active in surface analysis using TXRF and VPD/TXRF include: (a) American Society for Testing and Materials (ASTM), (b) Semiconductor Equipment and Materials International (SEMI), (c) Ultra Clean Society of Japan (UCS), and (d) International Standards Organization Technical Committee 201 (ISO TC/201). The standards activities are presently dynamic, and they are on an international scale, This paper provides an update on the status of these activities, and presents the challenges ahead yet to be resolved.
