450 mm Standards at SEMI
For over 40 years, the SEMI International Standards Program has been well-known for developing global consensus standards for the semiconductor industry. The first 2-inch silicon wafer standard, SEMI M1, was published in the early 1970s. As technology progressed, so did SEMI Standards. In 2008, SEMI published the first standard for the 450 mm generation.
Committees are now active in China, Europe, Korea, Japan, North America, and Taiwan, and there are also active participants in India, Singapore, and many other countries. Over 4,600 technical experts from leading companies in all segments of the semiconductor supply chain are currently involved in developing SEMI Standards.
Industry Participation is Critical
Progress is being made on the possible transition to 450 mm wafers and the development of corresponding standards is an essential industry activity to enable this future direction. The SEMI Standards Program allows companies to collaborate in a precompetitive environment to define standards that encourage technical innovation and market growth.
Companies that actively participate in the development process stay current with industry technology trends, and more importantly, influence the direction of the industry. Join us in this important effort. Registration is free and only takes a few minutes. Or, contact a SEMI Standards Staff member for more details.
