Nuvoton Technology Corporation Japan introduced the launch of its newest high-power violet laser diode, boasting an optical output of 4.5 watts at 402 nanometers, representing a 1.5-fold improve over its predecessor. The diode, designed to be used in maskless lithography techniques, will enter mass manufacturing in May.
The technological developments in Nuvoton’s new product are attributed to a proprietary gadget construction and enhanced warmth dissipation capabilities. The expanded design options handle widespread challenges confronted by violet laser diodes, akin to low wall-plug effectivity and thermal points, which beforehand restricted steady high-power operations.
By integrating this cutting-edge diode, Nuvoton goals to raise manufacturing throughput in optical gear used for superior semiconductor packaging. The firm’s new providing is especially vital for the rapidly-growing maskless lithography market pushed by synthetic intelligence demand, facilitating direct sample publicity from design knowledge and exact correction of substrate irregularities.
The laser diode additionally presents a viable semiconductor-based different to mercury lamps, catering to the wants of various optical purposes together with photocuring, 3D printing, and sensing. This aligns with the trade’s shift in the direction of wavelengths close to the mercury lamp i-line of 365 nm and h-line of 405 nm.
The new diode might be showcased at Nuvoton’s sales space throughout the Optics & Photonics International Exhibition (OPIE ’26) in Yokohama, Japan, from April 22-24, 2026.
