To sustain generations of feature downscaling on the wafer, photolithography itself has had to evolve. The advance of Complementary metal-oxide-semiconductor (CMOS) technology offers the opportunity to incorporate diverse microsensors with reading circuits on the same silicon substrate [3][4], acheiving the integration of an increased number of systems and electronic devices by integrated circuit (CI), allowing a reduction in cost per chip when produced in masse, In addition to the well-known wavelength challenges in optical lithography, sustaining increases in total layout information density-a doubling every two years or so, per Moore's Law-further strains pattern transfer capabilities and costs for advanced designs. Data points for transistor physical gate lengths, which typically are less than the half-pitch length, are also. In addition to the well-known wavelength challenges in optical lithography, sustaining increases in total layout information density-a doubling every two years or so, per Moore's Law-further strains pattern transfer capabilities and costs for advanced designs. A single, layout is decomposed into a set of relaxed-pitch mask pat-, terns, and the original layout image is reconstructed with, separate exposures of those masks combined with the aid, of etch and deposition processes. Fundamental to all of these processes is lithography, ie, the formation of three-dimensional relief images on the substrate for subsequent transfer of the pattern to the substrate. III.
