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.

Applied Materials lauches Centris platform for AdvantEdge MESA etch chambers, claiming 180 wph throughput, 0.8nm CD, and 30% lower CoO. Also releases new ultra HDP Silvia etch chamber for Centura, claiming $10 per wafer TSV etch.

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.

Researchers at MIT have demonstrated deep subwavelength lithography using a photochromic contrast enhancing layer, as reported in SciencExpress April 9. A thin photochromic film on top of a conventional photoresist layer was exposed to two wavelengths of light with two distinct patterns. One wavelength exposed the photoresist while the other made the photochromic film opaque […]

Applied Materials’ Technical Symposium at SPIE 2009 featured a panel discussion on next generation lithography (NGL) that was moderated by the company’s Ken MacWIlliams. The outstanding panelists were C. Grant Willson (UT-Austin), Burn Lin (TSMC), Jongwook Kye (AMD), Steve Radigan (Sandisk), and Milind Weling (Cadence). As would be expected from this panel, EUV steppers were […]

At the Nikon Lithovisions 2009 Symposium on February 22 this year in San Jose, California, Masato Hamatani described the features and beta test results for the NSR-S620 scanning immersion exposure tool, optimized for double patterning lithography. While the tool boasts only one wafer stage, its “Streamlign Platform” concept shoots 200 wafers per hour with 2nm […]
