The SEMI Standards program was established in 1973 using proceeds from the west coast SEMICON show. Its first initiative, following meetings with silicon suppliers, was a successful effort to set common wafer diameters to be used in silicon manufacturing. This standardization helped the industry avoid a wafer shortage from 1973 to 1974, that had previously been anticipated. The standards would become internationally utilized over the years, through partnerships with the ASTM, the DIN, and other national standards organizations. Before these standards, there were more than two thousand different specifications for silicon and by 1975 80% of all silicon wafers met with the SEMI standard. It was first published annually as the Book of SEMI Standards. With three new standards published annually in the mid-2000s, the book was eventually replaced with a CD-ROM, and now standards are available online on an annual subscription basis.
