Attenuated embedded phase shifting photomask technology can improve lithography performance for both g-line and i-line steppers. Emphasis at i-line is shifting from development to production as lithographers integrate phase shifting masks into their processes. This paper describes pilot production of i-line and g-line, Cr-based, attenuated embedded phase shifter photoblanks and photomasks.
