SEMI standards
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. [10] 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. [11] It was first published annually as the Book of SEMI Standards. [12] With three new standards published annually in the mid-2000s, the book was eventually replaced with a CD-ROM, [13] and now standards are available online on an annual subscription basis. [14]
Today, more than 1,000 SEMI standards and safety guidelines are available to address all aspects of automated fabs. The standards are developed and maintained by over 5,000 volunteer experts representing more than 2,000 companies, working in 23 technical committees and 200 task forces. [15] High-profile standards include wafer dimensions and materials, factory efficiency and reliability, equipment interfaces, and environmental, health and safety standards. [15] In 2022, SEMI published first ever a pair of Cybersecurity Standards, to help protect against future cyberattacks on factory equipment. SEMI E187 - Specification for Cybersecurity of Fab Equipment, and SEMI E188 - Specification for Malware Free Equipment Integration. [16]
The four main equipment communication standards are the SECS-I (which stands for SEMI Equipment Communication Standards) established in 1978 that deals with communication protocol and physical definitions, the SECS-II established in 1982 that deals with message format, the GEM established in 1992 that refines the SECS-II, and the HSMS that supersedes SECS-I established in 1994. [17] The organization also provides safety and ergonomics guidelines, the first of which was the SEMI S2 developed in 1993, followed by the SEMI S8 in 1995. [18]
Conferences and trade shows
SEMI was founded in 1970 as an association of semiconductor production equipment vendors. [17] At that time, most companies in the semiconductor industry exhibited at the Wescon Show on the west coast and the IEEE show on the east coast. Wishing to organize a show dedicated to semiconductor production equipment, 55 companies met in Palo Alto and agreed to found a new association, originally called Semiconductor Equipment and Materials Institute. [19]
The first SEMICON show was held in 1971 at the San Mateo Fairground in California, which featured “semiconductor processing equipment, materials, and service firms.” [17] It featured 80 exhibitors and attracted 2,800 visitors. [20] In 1973, the first SEMICON East show was held in New York City, with 120 exhibitors participating. This was followed by SEMICON Europa in Zürich, Switzerland (1975) and SEMICON Japan in Tokyo (1977), which attracted more than 200 exhibitors and 4,500 visitors. [20] Through this and other activities, the organization grew from a domestic organization to one with an international focus. [18] Part of this focus was to work with governments to reduce trade barriers and develop “a sympathetic regulatory climate” [21] for its member organizations—companies that sold equipment and materials to firms that produce microprocessors. [22]
Today SEMI organizes and produces nearly 100 technology showcases, trade shows, conferences and special events per year in all of the major manufacturing regions of the world. They include trade shows in China, Japan, Germany, Singapore, South Korea, Taiwan, North America, and Europe, as well as executive conferences, technical programs, and standards meetings. [23] [24] [25] The organization also has technical education programs, and a weekly email newsletter. Presentations delivered at its symposia are available to members of the organization on the Members Only section of the website. [12]
Market research reports
SEMI provides market research reports for the semiconductor equipment, materials, and LED industries. [24] Its billing data is considered an important leading indicator of demand trends and is closely watched within the industry and by semiconductor market analysts and investor. [26] It also releases the World Fab Forecast. [4]
The semiconductor equipment billings report provides a three-month rolling average of the book-to-bill ratio for semiconductor equipment manufacturers with headquarters in North America. It is released approximately three weeks after the close of each month. [27]
Data for the reports is collected directly from suppliers through a confidential data collection program via an independent financial services company. [28]
There are data collection programs in the following areas. [29] [30]
- Equipment market
- Packaging market
- Materials market
- Semiconductor Fabrication foundries and capacity
In-depth reports are broken down by region, supply chain segment, and equipment type.

Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically integrated circuits (ICs) such as computer processors, microcontrollers, and memory chips. It is a multiple-step photolithographic and physico-chemical process during which electronic circuits are gradually created on a wafer, typically made of pure single-crystal semiconducting material. Silicon is almost always used, but various compound semiconductors are used for specialized applications.
In electronics, a wafer is a thin slice of semiconductor, such as a crystalline silicon, used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells.

Consumer electronics or home electronics are electronic equipment intended for everyday use, typically in private homes. Consumer electronics include devices used for entertainment, communications and recreation. These products are usually referred to as black goods due to many products being housed in black or dark casings. This term is used to distinguish them from "white goods" which are meant for housekeeping tasks, such as washing machines and refrigerators, although nowadays, these would be considered black goods, some of these being connected to the Internet. In British English, they are often called brown goods by producers and sellers. In the 2010s, this distinction is absent in large big box consumer electronics stores, which sell entertainment, communication and home office devices, light fixtures and appliances, including the bathroom type.
Applied Materials, Inc. is an American corporation that supplies equipment, services and software for the manufacture of semiconductor chips for electronics, flat panel displays for computers, smartphones, televisions, and solar products.

Fabless manufacturing is the design and sale of hardware devices and semiconductor chips while outsourcing their fabrication to a specialized manufacturer called a semiconductor foundry. These foundries are typically, but not exclusively, located in the United States, China, and Taiwan. Fabless companies can benefit from lower capital costs while concentrating their research and development resources on the end market. Some fabless companies and pure play foundries may offer integrated-circuit design services to third parties.
Silicon Glen is the nickname given to the high tech sector of Scotland, the name inspired by Silicon Valley in California. It is applied to the Central Belt triangle between Dundee, Inverclyde and Edinburgh, which includes Fife, Glasgow and Stirling; although electronics facilities outside this area may also be included in the term. The term has been in use since the 1980s. It does not technically represent a glen as it covers a much wider area than just one valley.

In the early twenty-first century; foreign investment, government regulations and incentives promoted growth in the Indian electronics industry. The semiconductor industry, which is its most important and resource-intensive sector, profited from the rapid growth in domestic demand. Many industries, including telecommunications, information technology, automotive, engineering, medical electronics, electricity and solar photovoltaic, defense and aerospace, consumer electronics, and appliances, required semiconductors. However, as of 2015, progress was threatened by the talent gap in the Indian sector, since 65 to 70 percent of the market was dependent on imports.
The Chinese semiconductor industry, including integrated circuit design and manufacturing, forms a major part of mainland China's information technology industry.
