Abstract— Double patterning lithography (DPL) is in current production for memory products, and is widely viewed as inevitable for logic products at the 32nm node. DPL decomposes...
When VLSI technology scales toward 45nm, the lithography wavelength stays at 193nm. This large gap results in strong refractive effects in lithography. Consequently, it is a huge...
