WebThe subsequent proximity lithography machine has improved the contact lithography machine. A small gap is generated between the mask and the silicon wafer through the air cushion, and the mask and the silicon wafer are no longer in direct contact, but the imaging accuracy is not high due to the influence of the air cushion. . 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.
