INFICON was formed in June 2000 from the instrumentation businesses of three well-known international vacuum technology companies merged in 1996 under the Swiss company OC Oerlikon (formerly known as Unaxis). Our initial public offering was November 9, 2000, both on SIX Swiss Exchange and NASDAQ. In 2005, INFICON delisted its stock from NASDAQ. INFICON started to pay out dividends in 2006.
