WebDouble-patterning replaces a very challenging lithography step (with one expensive mask) with two simpler lithography steps (and two less expensive masks). You are trading off the additional cost and time required for a second patterning step for the simplification of the mask design. This concept can be extended to more than two masks. snap line in creoWeb25 feb. 2024 · Multiple mask lithography. The system, schematized in Figure 1B, is based on the use of several superimposed masks whose position can be controlled over time during the exposure phase, creating a gray-scale dose distribution over a specific area (Moser et al., 2012)..

The photomask blocks light in some areas and lets it pass in others. (Maskless lithography projects a precise beam directly onto the wafer without using a mask, but it is not widely used in commercial processes.) Exposure systems may be classified by the optics that transfer the image from the mask to the wafer. snap lines creo
