[Text|High-tech LED reporter Luo Shenghua] Benefiting from the heavy volume of downstream LED lighting demand, the LED chip industry has also tended to decline in the past years, continuing the supply and demand boom since the second half of last year. A number of LED chip companies have also accelerated the pace of expansion, mergers and acquisitions.
In addition, due to the higher than expected demand for PCs and servers, coupled with proper capacity management, chip companies have achieved good profits this year. According to industry analysts, the environment of the semiconductor industry in 2015 will continue to be favorable, and the current market environment may continue.
However, from the market feedback, although the chip is still in short supply in the first half of the year, the price has not rebounded, but the decline has stabilized. Moreover, the relative surplus of production capacity is further eroding the original meager profits of epitaxial chip manufacturers. How to highlight the encirclement and discover the new continent is imminent.
To change this situation, the chip factory itself must continue to innovate and improve the technical yield, while strengthening the cost control.
"The lower the performance of the luminaire, the higher the cost of the chip, the more the customer pays more attention to the price of the chip. However, as the chip size decreases, the profit margin is lower. Most small-sized chips on the market are sold at a loss." New Guanglian Semiconductor Research and Development Director Huang Huishi said at the 2014 High-Tech LED Annual Meeting on the morning of December 13th by Liyang Optoelectronics, the “Technology Driven Supply Chain Transformation New Opportunities†sub-forum.
In order to gain market competitiveness, companies are also innovating in technology, but whether new technologies can be truly successful requires enterprise efforts. "New equipment and new technologies are opportunities and challenges for small enterprises. How to take advantage of the advantages of small enterprises to seize opportunities is worth considering!" Huang Huishi said.
Taking 4, 6 inch epitaxy as an example, with the decline of the price of sapphire substrate, the advantages of large-size substrate will gradually appear. It is expected that the share of 4-inch epitaxial wafer will reach 80% or more in the next 2 years. The mosaic, warpage and etch consistency of the 4-inch PSS substrate, as well as the uniformity of 4-inch epitaxial growth, warpage control and yield, are all urgent problems to be solved.

As the drive current increases, the current, light and heat distribution inside the chip tends to be concentrated. Under high current drive, different product designs will cause the temperature difference inside the chip to reach 30 °C or higher, and the reliability of the accumulation point will be A significant drop, it is easy to damage the product. Therefore, product technology improvement and innovation are essential to ensure product quality.In order to gain market competitiveness, companies are also innovating in technology, but whether new technologies can be truly successful requires enterprise efforts.
