Breaking the technical bottleneck in the industry
340nm Short-Wave Near-Ultraviolet Vertical LED Chip
Born in a company in Taicang
And thus selected
ISA’s “Top 100 Global Semiconductor Lighting Innovations”
Recently, the International Semiconductor Lighting Alliance (ISA) held its 2025 member conference in Xiamen, where the “340nm Short-Wave Near-Ultraviolet Vertical LED Chip” developed by Suzhou Lifan Semiconductor Co., Ltd. won the “Top 100 Global Semiconductor Lighting Innovations” award.
“Traditional flip-chip short-wave near-ultraviolet LED chips suffer from low light efficiency due to total internal reflection at the interface between the epitaxial layer and the substrate, and the poor thermal conductivity of the substrate limits the chip’s heat dissipation capability, affecting its performance and lifespan,” said a representative from Lifan Semiconductor. These issues have long been a challenge in the industry. In response, Lifan Semiconductor has continuously increased its R&D investment, overcoming technical challenges to develop epitaxial growth technology and substrate separation technology, successfully achieving the preparation of vertical structure chips in this wavelength range, and launching the 340nm short-wave near-ultraviolet vertical LED chip, which has achieved goals such as light efficiency doubling, high current driving, and ultra-long lifespan, breaking the technical bottleneck in the industry.
“Being recognized as one of the ‘Top 100 Global Semiconductor Lighting Innovations’ is a validation and encouragement of our continuous improvement in technological innovation capabilities,” said a representative from Lifan Semiconductor. Currently, this 340nm short-wave near-ultraviolet vertical LED chip has been widely applied in high-end application scenarios such as industrial intelligence, biomedical, environmental technology, and material aging.
Suzhou Lifan Semiconductor Co., Ltd. was established in 2021 and focuses on strategic emerging fields such as intelligent transportation, new displays, and intelligent sensing, providing optoelectronic chips and other compound semiconductor optoelectronic products. The company possesses complete intellectual property rights across the entire industry chain of optoelectronic compound semiconductors, including epitaxy, chips, packaging, modules, and applications, with patents covering Europe, the United States, Japan, South Korea, and other countries and regions.
It is reported that the International Semiconductor Lighting Alliance (ISA) is a global non-profit organization established in 2010; the “Top 100 Global Semiconductor Lighting Innovations” award was first evaluated in 2021, with an independent scoring committee composed of well-known industry experts from around the world, aimed at promoting and facilitating the sustainable development of the global semiconductor lighting industry. The year 2025 marks the fifth evaluation of this award, with a total of 9 winning projects selected. To date, the “Top 100 Global Semiconductor Lighting Innovations” has recognized a total of 48 winning projects.
Chasing the new and the innovative
In Taicang, the semiconductor industry represented by chipsis competing in the “chip” race!
In recent years, the semiconductor industry in Taicang has developed rapidly, playing a significant role in forming an innovative pattern of “enterprise tiered cultivation and industrial high-end ascent” for advanced material industry innovation clusters. Currently, Taicang has formed an electronic information industry chain that includes computer and smart consumer devices, integrated circuits, and new displays, gathering a number of semiconductor chip companies.
In the future, our city will continue to create a favorable environment for scientific and technological innovation, accelerating the construction of a tiered cultivation system for technology-based enterprises, to boost the development of the semiconductor industry and seize new opportunities.
