Nichia
Nichia
Corporation (日亜化学工業株式会社, Nichia
Nichia
Kagaku Kōgyō Kabushiki-gaisha) is a Japanese chemical engineering and manufacturing company headquartered in Anan, Japan with global subsidiaries. It specializes in the manufacturing and distribution of phosphors, including light-emitting diodes (LEDs), laser diodes, battery materials, and calcium chloride.[3] The Nichia
Nichia
Corporation comprises two divisions — Division 1, responsible for phosphors and other chemicals, and Division 2, responsible for LEDs. In the field of phosphors the company has 50% of the Japanese market and 25% of the world market.[1][4] Nichia
Nichia
is the world’s largest supplier of LEDs. It designs, manufactures, and markets LEDs for display, LCD backlighting, automotive and general lighting applications with the many different leds across the entire visible spectrum. Nichia’s invention and development of white LEDs have spanned several accomplishments throughout the history of the company.

History[edit] The Nichia
Nichia
Corporation was founded in 1956 by Nobuo Ogawa (小川 信雄, 1912-2002) at Aratano-cho, Anan, Tokushima
Anan, Tokushima
to produce calcium phosphate for fluorescent lamp phosphors. The majority ownership is still held by the Ogawa family today. In 1966, Nichia
Nichia
began production of phosphors for fluorescent lamps. In 1971, Nichia
Nichia
began production of phosphors for color TVs. In 1977, Nichia
Nichia
began the production of tri-color phosphors for fluorescent lamps. One of Nobuo Ogawa's more well-known decisions was to support Shuji Nakamura to do research on gallium nitride light-emitting diodes, when it was generally considered a very risky business.[5] The research turned out to be a great success; however, the company received scrutiny for awarding a bonus of ¥20,000 (US$180) to Nakamura for his 1993 invention of the first high brightness blue-light LED, which was based on gallium nitride. Nichia
Nichia
later settled out of court with Nakamura for ¥840 million (US$7 million), in what was then the highest bonus ever awarded by a Japanese company.[6] Nichia
Nichia
supports financially a Polish company Ammono, which is the current (as of 2011) world leader in bulk Gallium Nitride (GaN) manufacturing of 2-inch diameter high quality bulk c-plane GaN substrates as well as non-polar M-plane, A-plane and semi-polar GaN wafer.[7] Nichia
Nichia
funds a joint research project with Ammono to develop ammonothermal gallium nitride growth, and in return Nichia
Nichia
took a stake in Ammono’s intellectual property, as well as access to the crystals that were made.[8] Several of Nichia's innovations have won awards, such as the Nikkei Best Products Award.[1] Japanese-born U.S. citizen Shuji Nakamura
Shuji Nakamura
won the Nobel prize
Nobel prize
for developing the blue light-emitting diode (LED) while working for Nichia
Nichia
corporation—the missing piece that now allows manufacturers to produce white-light lamps. According to Reuters, Nakamura invented the blue-light emitting diode while working at Nichia, but received next to nothing from the company for the work until 2004, when a Tokyo court ordered Nichia
Nichia
to pay him a record 20 billion yen ($185 million). The company appealed and Nakamura settled for about $8 million.[9] Major competitors[edit] Nichia
Nichia
Corporation's competitors include Seoul Semiconductor, Cree, Everlight Electronics, Lumileds, Epistar and Osram. Litigation[edit] In January 2006, Nichia
Nichia
launched a lawsuit against rival LED manufacturer Seoul Semiconductor
Seoul Semiconductor
Co., Ltd., alleging design patent infringement.[10] Nichia
Nichia
and Seoul Semiconductor
Seoul Semiconductor
announced that they have settled all litigation on patent and other issues as well as other legal disputes currently pending between them in the United States, Germany, Japan, United Kingdom, and Korea. The settlement includes a cross license agreement covering LED and laser diode technologies, which will permit the companies to access all of each other's patented technologies. In accordance with the settlement terms, all litigations are to be terminated by mutual withdrawal, with the exception of litigation in Germany involving patent DE 691-07-630 T2 of EP 0-437-385 B1, which was resolved following a February 2009 hearing.[11] References[edit]
