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.
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.
The 2010 SPIE Advanced Lithography conference is where we first get glimpses of the future of nano-scale patterning technology for manufacturing. Sometimes, many fuzzy blobs come into focus as a picture in a single moment, and Yan Borodovsky of Intel showed how to do 22nm node litho the day before SPIE officially started. At both […]
Another back-to-the-future possibility for next-generation lithography (NGL) is direct write e-beam (DWEB), revitalized with multibeam clusters, curvilinear mask writing, and character projection (CP). The E-beam Initiative used the recent SPIE gathering to announce that it had added six new member companies, including GlobalFoundries and Samsung. Aki Fujimura, CEO of D2S and Managing Director of the […]
This year’s plenary sessions of the SPIE Advanced Lithography Symposium exposed the complexities of patterning ICs in high-volume manufacturing (HVM) at the 22nm node and beyond. Steppers using 193nm ArF immersion (193i) will be extended using double-patterning (DP) schemes, since the extreme-ultra-violet litho (EUVL) infrastructure is again delayed. R&D to support DP integration has led […]
The SPIE’s 7th Frits Zernike Award for Advances in Optical Microlithography goes to M. David Levenson, BetaSights Litho & DFM Editor, in recognition of one of the most important developments in lithography resolution enhancement of the last twenty years, the phase shifting mask (PSM). About 30 years ago at the IBM San Jose Lab, Levenson […]
If EUV lithography is to succeed, infrastructure gaps will need to be addressed forthwith. The lack of inspection tools for EUV masks and substrates constitutes one such gap, now recognized as a priority by SEMATECH. At the OSA/APS Frontiers in Optics (FiO) meeting held in San Jose, October 11-15, Carmen Menoni of Colorado State University […]
Founded in 1984 with Flemish government support, IMEC has reached 25 years. To celebrate the organization’s accomplishments, BetaSights joined other industry media outlets attending a research review event in beautiful Leuven, Belgium. From 1999 to 2009 has been the “phase of international breakthrough” as described by current president Luc Van den hove. Working with OEMs […]
KLA-Tencor recently announced its long awaited 193nm reticle defect inspection tool, the Teron 600. Wafer scanners adopted 193nm exposure wavelength years ago in order to shrink circuit features below the resolution limit set by the previous (248nm) wavelength, roughly 130nm. The photomasks used in those tools, however, continued to be inspected at 257nm, in spite […]
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. Yan Borodovsky […]
