Lithography sadp
WebWafers were inspected at four different SADP steps shown in Fig. 2: formation of core line/space pattern (core lithography), first core etch (APF1), sidewall spacer deposition, … Webcomplementary lithography. Metal levels in DRAM and Logic chips can have more complicated patterns that can’t be done with SADP. These metal layers require Litho Etch Litho Etch (LELE) type double patterning rather than SADP. This technique requires two exposures and pattering steps per layer and is more expensive than SADP. Some further
