Domestic sapphire materials have been madly expanded from 2010 to 2011, and now the sapphire substrate plant is relatively cautious about the expansion of equipment. The mainland China sapphire material factory is basically 2 inches, compared with the 4-inch substrate film in South Korea, Taiwan and other places, the mainland factory is in the passive pricing power.
For the trend of the sapphire market, LED inside research assistant Wu Yingjie believes that the sapphire substrate market price has gradually come out of the bottom, the 2-inch sapphire crystal rod market benefited from the LED and non-LED market demand, the price of March began to pick up, The price falls on USD4.2~4.5; the 4-inch crystal rod market obviously benefits from the LED market demand, the price has come to USD16~18; the 6-inch crystal rod market has limited LED demand manufacturers, plus the original SoS market. Turning to the development of SOI technology, the price of 6-inch sapphire crystal sticks is still flat.
Thanks to the hot demand in the lighting market, the LED industry is not weak in the off-season; the use of sapphire substrates on smart phones is becoming more and more diversified, including the camera's protective lens and the Home button are beginning to introduce sapphire substrate materials. The demand for sapphire substrates continues to grow. Wu Yingjie expects that the supply and demand of the sapphire substrate industry will be balanced in 2014.
LED inside analyst Wu Yingjie said that from the development trend of epitaxial wafer size, chip manufacturers have been moving to large-scale epitaxial wafer production since 2012, thus increasing the demand for 4-inch sapphire substrates. LEDinside estimates that the production of 4-inch epitaxial wafers will be 41% of the total 2-inch capacity in 2013 and will grow steadily to 45% in 2017. The production of 4-inch epitaxial wafers will become the mainstream market development.
