The first SEMICON show was held in 1971 at the San Mateo Fairground in California, which featured “semiconductor processing equipment, materials, and service firms.” It featured 80 exhibitors and attracted 2,800 visitors. In 1973, the first SEMICON East show was held in New York City, with 120 exhibitors participating. This was followed by SEMICON Europa in Zurich, Switzerland (1975) and SEMICON Japan in Tokyo (1977), which attracted more than 200 exhibitors and 4,500 visitors. Through this and other activities, the organization grew from a domestic organization to one with an international focus. Part of this focus was to work with governments to reduce trade barriers and develop “a sympathetic regulatory climate” for its member organizations—companies that sold equipment and materials to firms that produce microprocessors.
