Challenges For Patterning Process Models Applied To Large Scale


Full-chip patterning simulation has been a key enabler for multiple technology generations, from 130 nm to the emerging 14 nm node. This span has featured two wavelength changes, a progression of optical NA increases (and a subsequent decrease), and a variety of patterning processes and chemistries. Full-chip patterning simulations utilize quasi-rigorous optical models and semi-empirical resist... » read more
