[Text / high- tech LED reporter Zhou Jin] With the gradual increase of the LED downstream application market, the entire industry chain has brought a positive drive, the price of each link of the LED industry chain is in a rapid decline channel. Taking the chip as an example, the overall market price has fallen by more than 70% in the past three years, with an average annual decline of nearly 30%.
Although the price decline has made the market competition more and more cruel, the technological improvement of domestic chip manufacturers has made the gap between themselves and imported chips smaller and smaller, and it has brought more market opportunities to domestic chip manufacturers.
As an upstream technology and capital-intensive area, there is always technology behind the growth of the chip market. This also brings new opportunities to domestic chip manufacturers. How many different chips are there in the future?
In 2013, the high-tech LED conference, on the afternoon of November 25th, the chip equipment and materials sponsored by Tiantong Gaoxin Group, Wu Donghai, technical director of Tongfang Optoelectronics and Lighting Industry, will "how many different chips are in the future" Make a keynote speech.
Wu Donghai believes that with the gradual maturity of technology, domestic chips and imported chips are no different. At the same time, with the increasing demand in the LED lighting market, there will be new demands arising from the reduction in LED production costs. "For the chip, the manufacturing cost should not be further reduced, but also continue to improve the luminous efficiency of the chip."
"The injection of high current has become an inevitable trend, and the chip area has to be gradually reduced." Wu Donghai said that the new demand has also put forward new requirements for the chip. The injection of large current requires the chip to have low Vf and excellent IV performance. Also have a low Droop effect and good heat dissipation.
With the development of the new Flip-Chip technology, the advantages of the Flip-Chip chip become more and more obvious. Wu Donghai believes that the new demand for the chip will be realized through this new chip technology. "New Flip- Chip chip technology can meet the market demand because of its good heat dissipation and high current injection."
Wu Donghai said that Flip-Chip technology will have obvious advantages especially for high-power products, while small and medium-sized power products, traditional dressing chips will still be the mainstream solution in the short term.
