For a time, silicon was once considered by the industry to be a promising GaN-based LED substrate material, which attracted a lot of investors' influx. International LED manufacturers and domestic companies have joined the battle for silicon substrate technology research and development and industrialization, but as far as the current progress is concerned, the situation seems to be not optimistic.
The reporter learned that in recent years, epitaxial chip manufacturers including Purui Optoelectronics, OSRAM, TSMC and Jingneng Optoelectronics have been actively working on silicon substrate LED projects. But to this day, a few companies have claimed to have developed products that are comparable in quality and performance to sapphire substrate chips, but they have not really entered the market.
However, Zeng Haoyan wants to realize the mass production of silicon substrate LED chips in 2013, such as Purui Optoelectronics, Toshiba, Osram and other manufacturers. Now, there is still no movement, and there is a fascinating trend.
Was the silicon substrate technology that was once optimistic, why did it linger in the laboratory stage, and will its industrialization road “borrow†halfway?
Comparison of the three major substrate technology routes
Purui Optoelectronics has announced that the company has shifted its focus from sapphire substrate LED manufacturing to lower cost silicon substrate LED manufacturing, and has also laid off nearly one-fifth of its staff at Livermore headquarters. Puri Optoelectronics insiders revealed to reporters: "At present, the technical personnel of Puri Optoelectronics Silicon Substrate LED Project have already left, basically will not continue.
Crystal Energy Photoelectric: Falling into the mud
Although Jiangxi Jingneng Optoelectronics has repeatedly announced new breakthroughs in the light efficiency and other parameters of its silicon substrate products, its industrialization seems to have fallen into mud. According to the industry, “there are a total of six silicon substrate epitaxial furnace equipments, and three of them have already been out of operation. The silicon substrate project has been slow and difficult to achieve mass production.â€
TSMC: low-key exit
A senior executive from Taiwan revealed to reporters that "the TS chip product of TSMC has actually come out, but the price/performance ratio is not particularly good. The light efficiency can basically reach 95% of Cree products, but the price is about 90%, basically There is no attraction, and the yield is not high.†Zhang Hongbiao, director of the High-tech LED Industry Research Institute, said that at present, TSMC has underway the silicon substrate project.
Sanan Optoelectronics: finally give up
Regarding whether Sanan Optoelectronics considers silicon or silicon carbide as the substrate, Li Xue, a securities affairs representative, said that it will not be considered at present. For the silicon substrate, the company has done a lot of experiments before, but finally gave up. Li Xue said that no matter whether it is hardness or strength, silicon substrates have no sapphire; while silicon carbide has advantages in high-power chips, but the current mainstream is medium power.
