[Text|High-tech LED reporter Jili] With the rapid growth of the LED lighting market and the expansion of the sapphire non-LED application market, the sapphire substrate has experienced a low in 2011 and 2012, and the market has gradually started since 2013. Warm up.
In LED applications, the demand for 4-inch sapphire substrates is rising rapidly, and it is expected that the growth rate will be over 30% this year and next. However, due to the sapphire manufacturer's production conversion from 2 inches to 4 inches, it is necessary to continue to expand production capacity due to the tight supply of 4-inch sapphire crystal rods and graphic sapphire substrates (PSS).
Zhejiang Dongjing Bolante Optoelectronics Co., Ltd. (hereinafter referred to as “Dongjing Bolantâ€) has been committed to the research and development and production of sapphire substrates since 2012, and introduced the high-efficiency sapphire graphic substrate technology to realize the industrialization of PSS. To meet the demand for high-brightness blue LED chips for PSS, it is one of the few companies in China to master the production technology of large-size sapphire substrate materials. Most of the PSS currently on the market is a 2-inch micron-sized PSS. The 4-inch micro-nano PSS of Dongjing Bolante has the advantages of graphic size, good shape consistency, high density and low defects.
In the 2014 (5th) High-tech LED Golden Globe Awards - Good Product Awards, Dongjing Bolant will carry LEDs with a 4-inch graphic sapphire substrate (PSS) model: D4(N)PSS.
Liu Jianzhe, deputy general manager of Dongjing Bolande, told reporters that in the current market where PSS is mostly 2 inches micron PSS, the East Crystal Boland 4 inch graphic sapphire substrate is quite competitive. The advanced technology is to use a high-density photoresist pattern mask or a self-developed SiO2 nanosphere as a mask (the invention patent: CN1022147443B), which is prepared by ICP dry etching technology. 4-inch hemispherical or triangular pyramidal PSS in nanoscale pattern size.
The East Crystal Bolander 4-inch sapphire substrate is excellent in technical parameters and use. The main performance indicators of the 4-inch product are as follows: 1. Graphical appearance: triangular cone 2. Pattern size: a width 2.7 microns high 1.7 microns b width 500 Nano high 300 nm 3. Uniformity: less than 3% 4. Graphic defects: <30 ea, 100-300 micron <3 ea, 300 micron or more 0 ea below 100 microns.
The traditional micro-PSS can no longer meet the requirements of further improving the light extraction efficiency of LED devices, and the LED industry's large-scale wafer era is also coming. Dongjing Bolante R&D team has 4 inch micro-nano PSS preparation technology with independent intellectual property rights, which effectively fills the blank of domestic large-size sapphire products. Since the establishment of the company at the end of 2012, it has been widely praised by LED epitaxial chip customers at home and abroad.
At present, Dongjing Bolant has reached 150,000 pieces of 2 inch PSS per month and 20,000 pieces of 4 inch PSS. It is estimated that by the end of 2014, the production of 4-inch PSS will reach 50,000. Dongjing Bolante will also play an early start, the leading edge of technology, so that product technology is at the leading level at home and abroad.
At present, the 2014 (5th) High-tech Golden Globe Award - the annual LED good product selection has entered the WeChat voting stage: August 8 - September 30.
