WebIntroduction As lithography moves deeper into the low-k1 regime, co-optimization of layout, mask, and lithography is critical to deliver a production-worthy patterning solution. The goal of co-optimization is to create a design, along with its corresponding resolution enhancement technology (RET) solution, that is relatively insensitive to manufacturing process variations. WebOptical Lithography. Photolithography is a patterning process in which a photosensitive polymer is selectively exposed to light through a mask, leaving a latent image in the polymer that can then be selectively dissolved to provide patterned access to an underlying substrate.
