Wafer Level Aluminum Nitride LED Technology Validated

With the support of the Technical Research Institute of the Ministry of Economic Affairs of Taiwan, No. 4 Research Institute of Suntech and Sun Yat-sen Science and Technology Co., Ltd. jointly developed wafer-level aluminum nitride LED technology with its 20W ultra-high power VISES series LED aluminum nitride encapsulated lamp beads. In November, the product successfully passed the quality verification requirements for the lumen maintenance rate (LM-80) of the US Energy Star Energy.

Under the government's Green Energy Technology Development Policy, the Technical Department of the Ministry of Economic Affairs of Taiwan plans the development of industrial technologies in the energy sector. Among them, the Chinese Academy of Sciences plans to develop high thermal conductivity wafer grade aluminum nitride technology due to its high thermal conductivity. Features such as high insulation, high breakdown voltage, and high electron movement rate make it the best electronic component insulation substrate.

Optimistic about the application prospects of aluminum nitride substrates, Caige Technology and the Chinese Academy of Sciences jointly develop wafer-level aluminum nitride LED technology, this technology integrates Gaician wafer-level packaging process technology, and Chinese Academy of Sciences wafer-level aluminum nitride package substrate Technology, and the introduction of technology into product development and mass production.

The adoption of aluminum nitride wafer-level LED packaging technology, the technology advantage of this technology is that the product development can be imported into the 8-inch semiconductor manufacturing process, to open a high industrial value for the Taiwan Foundry replacement equipment, and effectively reduce the cost of the process, according to The preliminary assessment of production volume has lower costs and higher yields than conventional conventional packaging.

After product testing, aluminum nitride packaged LED products VISES 9090 20W at 85 °C test temperature, the verification agency 6,000 hours lit experiment, product lumen maintenance rate of more than 95% on average, test data is higher than the LM-80 specification in The 91.8% lumen maintenance rate of indoor residences is also higher than the outdoor residential and commercial 94.1% lumen maintenance requirement. It shows that the aluminum nitride technology developed by the Ministry of Economic Affairs special project has excellent performance in ultra-high power LEDs. With the highest level of performance in the world and the introduction of high-power packaged components, the energy-saving effect will be better than that of general LEDs. It will provide a great guarantee for Taiwan's LED lamp manufacturers to pass the LM-80 test of LED lamp beads and mass production of high-quality products. And help to help it quickly cut into the global lighting market.

In addition, Caige Technology will also develop automotive, security surveillance (IR) and clean technology (UV) LED applications to meet the diverse needs of customers. The company, under continuous cooperation with the Chinese Academy of Sciences, will become the main support for LED lighting manufacturers to enter the global LED lighting market.
