会社のニュース UV technology innovation and high-end manufacturing empowerment

Ultraviolet light-emitting diode (UV LED) technology has rapidly evolved from its initial application in curing to become an indispensable "lithography tool" and "bonding expert" in the semiconductor, precision optical assembly, and high-end manufacturing fields. Thanks to its revolutionary breakthroughs in power density, wavelength stability, and long life, UV LED is accelerating industrial processes towards higher precision and efficiency.

In photolithography, a core process in semiconductor manufacturing, UV LEDs are showing great potential, particularly in the deep UV (Deep UV) band.

Traditional photolithography relies on bulky and expensive mercury lamps and physical masks. The latest deep UV microLED display array wafer technology, by providing highly efficient, high-resolution deep UV light sources, paves the way for low-cost, high-precision "maskless lithography." This greatly increases the flexibility of pattern exposure and is expected to significantly reduce manufacturing costs.

In precision manufacturing steps such as advanced packaging and wafer edge exposure, UV LED concentrated light sources, with their controllable, narrow-bandwidth spectrum, and stable output, have replaced traditional broadband light sources. This ensures uniform and precise photoresist exposure, which is key to improving chip yield.

UV LED light sources offer significant advantages in the active alignment and bonding of precision optical components, such as smartphone cameras, LiDAR sensors, and automotive headlights:

Active alignment requires fast and stable fixation of optical components using UV-curable adhesives after they are optimally positioned. UV LED light sources offer high radiant power, enabling rapid curing and effectively shortening production cycle times. Their low heat output (cold cure) prevents thermal shifting of aligned components during the curing process, significantly improving end-product reliability.

Industry leaders like Phoseon have demonstrated that industrial-grade UV LED lamps can operate for over 60,000 hours with highly stable light output. This long-term reliability is crucial for high-end manufacturing lines that operate.

UV LED technology is no longer a one-size-fits-all, standardized product. The future trend is to provide highly customized UV LED curing systems tailored to different substrates (such as plastics, glass, and composites) and production speeds.

Through advanced thermal management, precise heat dissipation, and integrated intelligent control systems, UV LED technology is providing core light source support for automated, green factories under the "Industry 4.0" model.
