Prof. Masato Shibuya was awarded the JSAP Takuma Award 2011 for invention of the phase-shift mask (PSM) and opening the field of advanced lithography, as reported by independent PSM inventor Marc Levenson.

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 […]

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 […]

At SEMICON West this year, ASML announced tools that fleshed out their Holistic Lithography scheme introduced at SPIE’s Advanced Lithography Symposium in February of this year. The key idea of Holistic Lithography, according to Bert Koek, senior vice president of the applications products group at ASML, is integrating computational lithography, wafer printing, and process control […]
