[Text|High-tech LED reporter Gan Qin] 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 decline in 2011 and 2012, and the market has gradually started since 2013. Warm up.
It is generally believed in the industry that the use of sapphire materials as LED chip substrates has many advantages: firstly, the production technology of sapphire substrate is mature and the device quality is good; secondly, the stability of sapphire is good, and it can be used in high temperature growth environment; finally, the mechanical strength of sapphire High, easy to handle and clean. In addition, the sapphire substrate is moderately priced and easy to scale.
Tiantong Holdings Co., Ltd. (hereinafter referred to as "Tiantong Holdings") has been committed to the research and development and production of sapphire substrates since 2010. It is one of the few companies in China to master the production technology of large-size sapphire substrate materials. In 2013, Tiantong Holdings has formed a scale of 100 sets of 90Kg crystal growth furnaces, leading the industry peers.
“The company has made significant innovations in the technology of long crystal technology. The 4-inch sapphire substrate adopts the self-developed TKY-2 method crystal growth technology, which can not only grow A crystal, but also grow C crystal, which has quality and cost. The core competitive advantage.†Pan Jianqing, chairman of Tiantong Holdings, said that the company C has originality to the sapphire crystal technology and has applied for 11 patents, including 7 invention patents.
According to reports, Tiantong Holdings large-size substrate has excellent reaction between technical parameters and use end. The main performance indexes of 4-inch products are as follows: 1. Surface roughness: Ra<0.2nm; 2. Back: Ra: 1.0±0.3um; , warpage: 0~-10um; 4, bending degree: ≤15um; 5, crystal performance index: C to 150K, crystal maximum size up to 15 inches, dislocation density below 600pit/cm2, rocking curve half height and width 15 arc Less than seconds.
2014 (5th) High-tech Golden Globe Award--The annual LED good product selection has been opened, and has entered the enterprise registration stage (June 7-July 31). Known as the “Oscar for the LED industryâ€, this year, it attracts many well-known companies from the industry. This time, Tiantong Holdings will participate in the Golden Globe Awards with the above 4-inch sapphire substrate.
Pan Jianqing said, "At present, the company has stabilized the production of C to 90Kg sapphire crystal and 4 inch substrate, effectively filling the blank of domestic large-size sapphire products. The successful development of C to 150Kg 15-inch sapphire crystal also shows the leading of Tiantong. R & D capabilities." It is reported that 15-inch sapphire window material (C-direction) can effectively replace imported materials.
