Lithography fabrication

WebLithography is the heart of the semiconductor fabrication process. It is used to pattern specific shapes of a thin layer on a rigid substrate for fabricating electrical devices. … WebIn the Rayleigh criterion equation, CD is the critical dimension, or smallest possible feature size, and λ is the wavelength of light used. NA is the numerical aperture of the optics, defining how much light they can collect. Finally, k1 (or the k1 factor) is a coefficient that depends on many factors related to the chip manufacturing process.
