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 focus the pattern onto a photosensitive silicon ... WebFor this measurements openings in resist are needed, it means you have to make lithography and develop. Unexposed areas (where thickness is measured) are developed very slow, too. This "dark...

WebThus, the erosion of the exposed resist during development is rather high, the resist starts thinning. An exposure dose too high also illuminates nominal dark re-sist areas via scattering, diffraction, or reflection. As a consequence, the resist structures re-maining after development are much larger than determined by the photomask.
