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 ... WebDeep UV Photolithography. DUV technology for photolithography is exclusively based on projection optics since the pattern on the photomask is much larger than the final pattern developed on the photoresist. The …
