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 […]
