  1. 2004 Update to Lithography Chapter of the ITRS Masaomi Kameyama Chairman of the Japan Lithography Technical Working Group

  2. Changes to Litho Tables for 2004 • CD control (total CD control) • US and Japan TWG studies concluded that <4nm 3s CD control has no known solutions • CD control will remain red for the present and future nodes • Definition of potential solutions • More specific criteria for N to N+2 nodes • N+3 node and beyond may be more broad ranging and inclusive • Changes to coloring, footnotes, etc. • Definition of overlay in Tables 77a and 77b • Mask table values updated • Resist table values updated • More discussion needed (2005 update probable) • LWR/LER definitions and values with input from PIDS, FEP and Metrology • APC requirements

  3. New criteria for potential solutions • All infrastructure (masks, tools, resist,…) needs to be in place to meet the ramp for the specified node • Technology must be planned to be used by IC makers in at least two geographical regions • For nodes with black coloring, the requirement to have more than one region support is not applicable • Technology should be targeting leading edge critical layer needs • Consideration (not a requirement): 100 tools worldwide over the life of that tool generation
