Semiconductors are present in many common electrical and electronic devices. As semiconductors have evolved over the years and become more integrated, cleanliness and purity during the wafer manufacturing process have become essential. At the same time, fabrication requires the use of aggressive liquids, gases and plasmas and occurs under extreme temperature and pressure conditions. The requirement of purity in combination with a harsh environment presents many challenges. Trelleborg’s high-performance seals are engineered to withstand the toughest conditions guaranteeing the cleanest environment for semiconductor device manufacturing.
