http://ltj-ts.jp/pdf/A-0.pdf 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 ...

Web25 jan. 2015 · Optical projection lithography is one of the enabling technologies that have driven the fast paced development of micro- and nanoelectronics over the past decades. First optical projection systems were introduced in the mid-seventies to manufacture microelectronic circuits with approximately 2 μ m wide features.
