Sapphire Substrates to Face Another Growth Peak

According to the latest ‘Global Sapphire Substrate Market Report’ published by the LED inside research department of market research institute TrendForce, sapphire substrate manufacturers are optimistic about the emerging demand for non-LED market applications in 2013 such as handset device applications, silicon-on-sapphire (SOS), and window films. With such prospects in the future, there are still many manufacturers fighting over the non-LED applications, with plans for production despite the low market prices, the firm adds.

Due to oversupply, sapphire substrate quality requirements from LED epiwafer manufacturers have risen, notes LEDinside. Existing LED makers are more willing to use sapphire ingots grown by the Kyropoulos (KY) method, so it has become even more difficult for most new-comers to enter the LED supply chain. Therefore, except for first-tier manufacturers, the utilization rates of most sapphire ingot manufacturers have been below 50%. However, since the introduction of sapphire for camera lenses in Apple’s iPhone5, demand for sapphire substrates from non-LED applications has begun digesting part of the excess production, bringing the sapphire substrate industry into a virtuous cycle.
