Tokyo Electron Limited (東京エレクトロン株式会社 Tokyo Electron Kabushiki-gaisha), or TEL, is a Japanese electronics and semiconductor company headquartered in Akasaka, Minato-ku, Tokyo, Japan.[2]

TEL is best known as a supplier of equipment to fabricate integrated circuits (IC), flat panel displays (FPD), and photovoltaic cells (PV).[2] Tokyo Electron Device (東京エレクトロンデバイス株式会社 Tokyo Electron Device Kabushiki-gaisha, TYO: 2760), or TED, is a subsidiary of TEL specializing in semiconductor devices, electronic components, and networking devices.[2]

As of 2011, TEL is the largest manufacturer of IC and FPD production equipment in Japan and the third largest in the world.[2] The company was founded as Tokyo Electron Laboratories, Inc. in 1963.

On September 24, 2013 Tokyo Electron and Applied Materials announced a merger.[5] If approved by government regulators, the combined company, to be called Eteris,[6][7] would be the world's largest supplier of semiconductor processing equipment, with a total market value of approximately $29 billion. On April 26, 2015 the merger was cancelled to due anti-trust concerns in the United States.[8]


On November 11, 1963, Tokyo Electron Laboratories Incorporated was founded by Tokuo Kubo and Toshio Kodaka, largely funded by Tokyo Broadcasting System (TBS), with a capital of over five million yen. Later that year, their office opened in the TBS main building and began manufacturing thousands of quality-control and importing diffusion furnaces made by Thermco and selling Japanese-made car radios.[9]

In 1965, the company approached a rapidly growing business in the market, Fairchild Semiconductor Corporation and agreed to serve as a sales agency for them, increasing their capital to twenty million yen and began exporting IC testers, IC sockets, IC connectors, and other similar computer components.[9]

They opened a new office in San Francisco, California and their new branch, Pan Electron in 1968 establishing themselves as the only stocking distributor of imported electronic components in the region.[9]

One year later, they opened their still-functioning Yokohama office and established Teltron, a major manufacturer and distributor of car stereos, expanding their headquarters to fill the entire TBS-2 building and raising their capital to 100 million yen.[9]


Semiconductor Production Equipment (SPE)

TEL produces Semiconductor Production Equipment (SPE) for the following purposes:[2]

Thermal processing
Deposition of thin layers of dielectric material between transistors onto the silicon wafer surface in a heated low-pressure chemical vapor deposition (LPCVD) or oxidation process[10]
Photoresist coating/developing
Photoresist coating and developing to project a microscopic circuitry pattern on the wafer in photolithography[11]
Plasma etching[12]
Wet surface preparation
Wafer surface cleaning to remove foreign particles or contaminants such as dust[13]
Single wafer chemical vapor deposition
Deposition of thin layers of various materials, such as tungsten, tungsten silicide, titanium, titanium nitride, and tantalum oxide[14]
Wafer probing
Wafer probers for testing the functionality and performance of each die on the wafer[15]
Material modification/doping
Surface modification and doping using gas cluster ion beam (GCIB) technology[16]
Corrective etching/trimming
Corrective etching and trimming of thin films such as silicon, silicon nitride, silicon dioxide, aluminum nitride, and metals[17]
Integrated metrology (co-developed by TEL and KLA Tencor)[18]
Advanced Packaging[19]

Group companies

The Tokyo Electron Group consists of TEL and the following subsidiaries:[1][20]

Research and development

TEL's Leading-edge Process Development Center is located in Nirasaki, Yamanashi. TEL also has the Kansai Technology Center in Amagasaki, Hyogo Prefecture and the Sendai Design and Development Center in Sendai, Miyagi Prefecture. TEL Technology Center, America, LLC in Albany, New York is the R&D center in the United States. TEL is one of the partners of IMEC, a microelectronics and nanoelectronics research center in Leuven, Belgium.[1]

In July 2014, TEL announced the establishment of joint assembly lab with Institute of Microelectronics in Singapore. The lab is focused on the research and development of Wafer Level Packaging and assembly, to address the need of Internet of Things with devices of high performance and low power consumption.[21]


Tokyo Electron Hall Miyagi in downtown Sendai

TEL supports association football in Japan by sponsoring the J. League as a whole and the football club Ventforet Kofu based in Kofu and Nirasaki as well as the rest of Yamanashi Prefecture.

The company has acquired naming rights of two multipurpose halls:
