SPIE Advanced Lithography 2011 showed few new tools or techniques, but many new materials and integration tricks to extend 193i into double-patterning for IC HVM, while EUV and DSA developments continue according to expert Dr. M. David Levenson of BetaSights.

E-beam Initiative adds four members and starts on Design for E-beam (DFEB) for mask makng for ICs to reduce mask costs at 22nm and below.

Post-optical lithography (NGL) technologies EUV (EUVL), e-beam direct-write (EbDW), and nano-imprint (NIL) all need work as shown at SEMICON/West 2010, major costs limitations.

While EUV Lithography may now be inevitable, according to SEMATECH Program Manager Bryan Rice, it may not be indispensable. SEMICON West offered a snapshot of progress towards the 32nm, 22nm, and 16nm device nodes at the Device Scaling TechXPOT, and the industry appears to have patterning options even if EUV encounters further delay.
