In 2014, the production capacity of LED sapphire crystal ingot equipment increased by 53%.

Patterned substrate manufacturers have benefited from the large-scale introduction of patterned sapphire substrates by LED chip manufacturers in Taiwan and Mainland China to improve luminous efficiency. For example, manufacturers such as Ruijie, Zhaoyuan, Zhejiang Crystal, and Dongguan Zhonggao have switched from 2-inch to 4-inch wafer production, and all have good performance. The output value of the patterned substrate market has increased by 8% annually from US$656 million in 2013. From a long-term perspective, due to the increase in the rate of LED manufacturers importing patterned substrates and the increase in the production of large-size wafers, the agency estimates that the output value of the patterned substrate market will increase to US$1,098 million in 2016.
