Web1 feb. 2010 · 1. Introduction. Computer Generated Hologram (CGH) is widely used for testing of large aspheric surfaces. It, however, is difficult to fabricate by the well-known E-beam methods because most of the CGH requires a large diameter (ø75 to 1,000 mm) and a tough precision (position accuracy of each line in the CGH should be less than 50 nm.). WebMikrochips show structures 5,000 times finer than a human hair and are produced with light of the extremely short wavelength of 13.5 nanometers. For this purpose, EUV lithography optics from ZEISS SMT are used in production (no distribution in Germany). EUV technology is pushing the boundaries of what is technologically possible.
Semiconductor Lithography (Photolithography) - The Basic Process
Lithography uses simple chemical processes to create an image. For instance, the positive part of an image is a water-repelling ("hydrophobic") substance, while the negative image would be water-retaining ("hydrophilic"). Thus, when the plate is introduced to a compatible printing ink and water mixture, the ink will adhere to the positive image and the water will clean the negative image.
