Nitride Semiconductors Co., Ltd.

Nitride Semiconductors Co., Ltd. (ナイトライド・セミコンダクター株式会社) is a Japanese semiconductor company based in Naruto, Tokushima Prefecture, dedicated to ultraviolet light-emitting diodes (UV-LEDs) and related crystal-growth technology. The company presents itself as the pioneer of UV-LEDs, stating that it succeeded in the world's first mass production of UV-LEDs in 2000. Its core competence is crystal growth technology, which underpins a product portfolio spanning GaN wafers (n-GaN, p-GaN, u-GaN), UV-LED wafers and bare chips, micro UV-LEDs, LED lamps, high-power surface-mount (SMD) devices, deep-UV LED SMD and COB units, and finished UV irradiation systems such as shower boxes, flood lights, flashlights, fluorescent-lamp-type UV lights, irradiators, high-power mini irradiators and 3D limelight products. The company also offers customized products. Nitride Semiconductors serves applications including sensors, resin curing, photocatalysis, display and lighting, and disinfection/sterilization. Its UV-LED Power SMD products, for example, are high-power devices with large-area chips intended for exposure light sources and curing of resins and inks, offered at wavelengths such as 365 nm, 385 nm, 395 nm and 405 nm. Its UV-LED bare chips cover wavelengths around 355–375 nm. The company has also worked on micro UV-LEDs with photonic crystals and on micro UV-LED displays, reflecting an R&D orientation toward next-generation display and photonic applications. The company is led by representative director (CEO) Yoshihiko Muramoto, who also writes the company's "Nitride Story" (NS Story) column. Under his leadership the firm has received recognition including being named a Top UV-LEDs Manufacturer in APAC 2026 and his selection among CEO Insights Asia's Top 10 Leaders From Semiconductors Japan. Nitride Semiconductors is a specialist, technology-driven supplier rather than a mass-market consumer brand, positioning itself as a UV-LED pioneer and core crystal-growth technology provider for industrial and scientific customers in Japan and overseas.

Nitride Semiconductors Co., Ltd. was founded in 2000 in Naruto, Tokushima Prefecture, Japan, and in the same year achieved what it describes as the world's first mass production of UV-LEDs. This founding achievement established the company as a pioneer in the ultraviolet LED field. From the outset, the company's core technology has been crystal growth, which it has continued to develop as the foundation for its GaN wafer and UV-LED product lines. Over the following decades, Nitride Semiconductors built a portfolio that spans the value chain from materials to finished systems. It supplies GaN wafers in n-GaN, p-GaN and u-GaN types, UV-LED wafers and bare chips, micro UV-LEDs, LED lamps, high-power surface-mount (SMD) modules, deep-UV LED SMD and COB units, and finished UV irradiation equipment such as shower boxes, flood lights, flashlights, fluorescent-lamp-type UV lights, irradiators, high-power mini irradiators and 3D limelight products. The company also offers customized products and maintains an R&D effort that has extended into advanced areas such as micro UV-LEDs with photonic crystals and micro UV-LED displays. The company has received a number of technology awards over its history, which it cites as evidence of its technical strength. Its representative director, Yoshihiko Muramoto, has led the firm and has been publicly recognized in the semiconductor industry; in December 2025 he was selected among CEO Insights Asia's Top 10 Leaders From Semiconductors Japan, and in July 2026 the company was selected as a Top UV-LEDs Manufacturer in APAC 2026. In March 2026, Muramoto delivered a keynote speech titled 'Micro Ultraviolet LED with Photonic Crystal' at OPTICS2026 in London, illustrating the company's continued emphasis on photonic-crystal-based micro UV-LED research. The company communicates with customers and the public through its website, product catalogs, technical explanations of UV-LED applications, and the 'Nitride Story' (NS Story) column written by its CEO.
