Why standards?

The SEMI International Standards Program is one of the key services offered by Semiconductor Equipment and Materials International (SEMI) for the benefit of the worldwide semiconductor, photovoltaic (PV), LED, MEMS and flat panel display (FPD) industries. Standards offer a way to meet the challenges of increasing productivity while enabling business opportunities around the globe. The program, started over 40 years ago in North America, was expanded in 1985 to include programs in Europe and Japan, and now also has technical committees in China, Korea and Taiwan.

In 1997, the Program was expanded to cover other areas with activity in these industries among suppliers and users. The program operates as a neutral forum for the exchange of information among suppliers and users resulting in the production of timely and technically accurate specifications and other standards of economic importance to the industry. It is a vehicle for networking, partnering, and professional growth. Over 5,000 technologists worldwide, representing both device manufacturers and equipment and materials suppliers, participate in the program. These individuals work toward resolving a variety of process and product related issues in both the front and back-end areas in semiconductor, photovoltaic, and flat panel display manufacturing.

What are standards?

Standards are voluntary technical agreements between suppliers and customers, aimed at improving product quality and reliability at a reasonable price and steady supply. Standards ensure compatibility and inter-operability of goods and services.

SEMI standards are written documents in the form of specifications, guides, test methods, terminology, practices, etc. These documents are published in the 16 volume set of SEMI International Standards. SEMI standards cover every aspect of photovoltaic and semiconductor manufacturing: 3D-IC, Equipment Automation (Hardware and Software), Facilities, Gases, High Brightness-LED, MEMS/NEMS, Materials, Microlithography, Packaging, Photovoltaic, Process Chemicals, Silicon Material & Process Control, and Traceability. Guidelines are also developed to cover safety related issues. In addition, standards are published for Flat Panel Displays. The publication catalogue provides a listing of the available standards and guidelines.

What are the benefits of participating?

The SEMI International Standards Program is first and foremost an opportunity for industry representatives to participate in state-of-the-art technical discussions, while also establishing the future direction of the semiconductor, photovoltaic, and FPD industries. By participating in standards, companies can influence important industry trends.

Companies utilizing standards can decrease manufacturing costs, increase reliability and productivity, and access global markets. On an individual basis, participation helps to reduce design work, provides access to evolving technology and technical developments, and aides personal development.

How are standards developed?

The SEMI International Standards program provides the framework and procedures for industry experts to meet, discuss, and develop essential standards and guidelines. Once the need for a standard has been identified with appropriate input from the user community, a task force is assembled to carry out the development effort. The task force may be regional or international. The result of the task force deliberations is a draft document responsive to industry needs. The draft is reworked until the task force develops consensus. After the task force is satisfied with its work, a wider consensus is developed by reporting to the parent regional technical committee or subcommittee to obtain comments from other members who did not participate directly in the document development. Frequently, broader international consensus is also obtained informally at this time.

When the regional technical committee agrees that a reasonable consensus has been reached, it initiates the worldwide balloting process to confirm that the document has global consensus. This process is managed by the SEMI Headquarters office. Regional offices in China, Europe, Japan, Korea, and Taiwan provide additional direct member interface. At least 60% of the issued ballots must be returned, so it is very important for ALL registered technical members to vote. All negative viewpoints must be considered, but unanimous agreement is not required.

The culmination of this development effort is the application of the new standard by the industry. Frequently, SEMI organizes Standards Technical Educational Programs (STEPs) to communicate new standards to the industry and show the advantages of using them. Users cite SEMI standards in their purchase specifications or utilize them in equipment and materials evaluations. Suppliers cite conformance of equipment, materials, or services to SEMI standards in their advertising and product literature. Use of SEMI standards is entirely voluntary, and so their usefulness to the industry can be assessed by the frequency of use.

Management of the program is provided by industry volunteers serving on administrative Regional Standards Committees in North America, Europe, and Japan. These committees also consider the document history to determine that all the mandated procedures have been followed, and that all opinions have been properly considered. The International Standards Committee has the overall responsibility for the conduct of the program. It establishes the regulations governing the program procedures and maintains relationships with other standard-setting organizations worldwide.

Benefits of Standards

Standards are a form of technology that transcends international boundaries. More importantly, SEMI Standards development conducted on an international basis spurs the dialogue that results in joint ventures, technology licenses, and outright sales. Standards are not just developed by and for engineers; their use should be viewed as a management tool, and consequently should be accompanied by high level support for standards-setting activities.
