WebHow it all began. Advances in the area of camera lenses enabled Carl Zeiss AG to produce novel optics for lithography for the company Telefunken in 1968. In 1977, ZEISS unveiled the S-Planar 10/0.28, the first lens to enable the opto-lithographic production of 1 µm structures. This laid the foundation for the first wafer stepper.
