Semiconductor Lithography (Photolithography) - The Basic Process

WebLithography is a printing process that uses a flat stone or metal plate on which the image areas are worked using a greasy substance so that the ink will adhere to them by, while … Weblithography using the following Rayleigh’s formula (3); R = k1 × λ/NA, where λ is the exposure wavelength, NA is the numerical aperture of projection optics, and k1 is a constant depending on the lithography process. As k1 decreases, the lithography becomes more difficult. The theoretical lower limit of k1 is 0.25 for the projection diamond wire for granite cutting

WebA lithography (more formally known as ‘photolithography’) system is essentially a projection system. Light is projected through a blueprint of the pattern that will be printed (known as a ‘mask’ or ‘reticle’). With the pattern encoded in the light, the system’s optics shrink and … Rayleigh criterion equation. In the Rayleigh criterion equation, CD is the critical … Creating EUV light.
