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.
