Production of optical systems for semiconductor manufacturing
ZEISS SMT develops future technologies at Oberkochen, makes them ready for series production and manufactures them on site. Mirrors and lenses are ground in some buildings, polished to high precision in others and then coated, and in the cleanrooms the frame parts from the high-precision mechanical production are assembled with the lenses and mirrors and adjusted with sub-micron precision. More than 2,700 people are employed in Oberkochen to produce optical systems for semiconductor manufacturing. A site expansion whose groundbreaking ceremony was in May 2022 is creating around 25,000 square meters of additional space there for production and production-related areas.
All in all more than 2,700 people are employed in Oberkochen to produce optical systems for semiconductor manufacturing.
