San’an has completed a 30 percent transition from 2 inch to 4 inch sapphire substrate, and strives to reach 70 percent and above by next year, said  the company’s Chairman Secretary Li Xuetan.

The LED industry’s fierce price competition is putting manufacturers under increasing pressure to cut costs. To stand out from the crowd, Russia based manufacturer Monocrystal has sought alternative sapphire substrate market applications other than LEDs, such as smartphone markets. Mikhail Berest, Senior VP Global Sales Director, Monocrystal sheds light on the company’s sapphire substrate technology that has enabled these high end applications at day one of LEDforum Taipei 2013 that took place at Evergreen International Convention Center on Oct. 16-17, 2013.

With the unchanging trend of falling LED prices, chip manufacturers are constantly improving LED chip production process and technologies to lower costs. Semiconductor equipment company GT Advanced Technologies (GTAT) has developed Hydride Vapor Phase Epitaxial (HVPE) system that can replace nGaN and uGaN growth process in MOCVD. In the future, LED chip manufacturers can add HVPE systems to speed up epitaxy growth rates. Compared to adding MOCVD to expand production capacity, using HVPE system can increase production capacity and help LED chip manufacturers cut up to 25 percent of costs.
