M & M published 8 inch wafer level LED silicon based packaging technology

The day before the caijue science and technology published 8 inch LED silicon wafer level packaging technology, by the industry as a new breakthrough for the high power LED package; and in addition to innovative technology, but also because of TSMC caijue investment background, has been the focus of attention of the outside world.

Reporters recently in an exclusive interview with caijue science and technology general manager and CEO Mr. Lin Shunkichi, development and quality assurance organization deputy general manager Dr. Xie built and career development two director Mr. Ceng Defu, in-depth study of wafer level LED package LED package advantages and future market trends.

Caijue science and technology with rich experience in semiconductor manufacturing and exquisite manufacturing technology, heat radiation, LED packaging technology developed has excellent temperature control, and can be customized optical lens, in order to enter the LED industry to provide LED OEM service package. With quality management system, continuous improvement plan, long term internal training, audit and verification, it is able to provide continuous quality improvement to meet customer needs. And through the product engineering services, to achieve good yield control, thereby improving yield. To meet the needs of different customers, can also be combined with technology import or customized process services to meet customer expectations of differentiation.

The development of wafer level high power light emitting diode packaging technology with core optics and silicon packaging technology.

8 "silicon wafer high power LED base package

Morphological comparison of traditional high power LED packaging, packaging technology caijue science and technology has many advantages, such as good heat dissipation, reliability (due to the thermal expansion coefficient of silicon is consistent with the LED chip), control the consistency of color temperature (fluorescent powder coating because of high uniformity, miniaturization (wafer level) lens mold and MEMS) and elastic customized polycrystalline display design and layout.

Wafer level LED packaging technology thermal characteristics color temperature consistent small size

Caijue 8 inch LED silicon wafer level packaging technology, is the use of patented micro semiconductor MEMS fabrication through silicon perforation, mold lens and uniform fluorescent material coating exclusive technology, the whole piece of package and then cutting, mass production and reduce costs; in the single crystal LED packaging products is expected to drop to thermal resistance 2Co/W, and significantly reduce the interface temperature (junction temperature < 50Co at Ta=25Co).

R & D Vice President Dr. Xie further explained that compared with the traditional plastic or ceramic package caijue LED silicon based packaging technology, can greatly improve the heat dissipation efficiency of 50%, in order to prolong the service life of the components, and increase durability and reliability. On the other hand, the use of special research and development process of wafer level, consistency of color and temperature control, effectively improve the yield; and is suitable for miniaturization and display design of multiple grains, according to market and customer demand, further reduce the volume of the product, reduce the cost of products.

LED packaging technology new milestone monthly production capacity of 3 million high power

CEO Lin said that although the LED silicon wafer level package is a new milepost LED packaging technology, but this technology could still be imitated, at this stage of production is the biggest advantage of Yu their market leader, manufacturers will be difficult to catch up with them; secondly, in the economic scale, caijue with the fine material with the semiconductor and some equipment, a large number of cost can be saved early, with additional investment to achieve the fastest effect, cost-effective; finally is the production technology, optical design and experience accumulated over the years, able to provide customers a full range of solutions, and create more business opportunities by product.

In terms of production, to 1W LED to calculate the average monthly production capacity of more than 3000000, the yield is maintained within an acceptable range, and next year is expected to expand production 5-10 times, depending on the needs of the terminal market to make adjustments.
