Sapphire wafer prices rising due to growing demand, say Taiwan makers
Julian Ho, Taipei; Adam Hwang, DIGITIMES [Tuesday 30 July 2013]
Global demand for sapphire wafers is growing due to use in smartphones in addition to LEDs, and therefore prices of sapphire wafers are rising, according to Taiwan-based sapphire wafer makers.
Apple has taken the initiative to use sapphire wafers to make the protective cover on the iPhone 5 rear camera, and LG Electronics and Samsung Electronics have followed suit for their high-end smartphones, the sources indicated. An estimated 1.5 million 2-inch sapphire wafer equivalents are used in iPhone 5 production each month, and additional monthly demand for sapphire wafers from LEDs is about 4.5 million 2-inch units, the sources said. In particular, LED lighting is expected to increase demand for PSS (patterned sapphire substrates), the sources noted.
