According to statistics, as a large number of LED manufacturers continue to march upstream, the demand for MOCVD equipment has expanded dramatically. In 2011, only the equipment purchases in the Asia-Pacific region are expected to exceed 1,000. Through the transmission, the demand for LED sapphire substrates in the global market will be violent. As a result, the supply and demand relationship of sapphire substrates will gradually surface. He Zaihua, a senior researcher at China Investment Consulting, pointed out that in the current substrate technology, the sapphire substrate dominates with absolute advantages. Nichia chemistry and Toyota Synthetic are both sapphire substrate technologies. In large LED companies, CREE uses silicon carbide substrates. Because of its mature silicon carbide generation technology, it has formed a monopoly in the field of silicon carbide. Situation. For most merchants, the choice of sapphire substrates with mature technology is significantly better than the cost-effective silicon carbide technology. Among them, the price/performance ratio is the reason why sapphire substrates can seize the market, and there is no large-scale development of silicon carbide and GaN substrates. s reason. In 2010, the backlight panel was the absolute force to drive the demand for sapphire substrates. Among them, the shipments of mobile phones, monitors, LCD TVs and other industries directly stimulated the demand for sapphire substrates. As the penetration rate gradually increased, the mobile phone field The growth trend is gradually slowing down. Next, the large demand for sapphire substrates will be reflected in the large-scale demand for LCD TVs. In December, the "flat-panel TV energy efficiency limit value and energy efficiency rating" will be implemented, which will give LED LCD TVs Demand has opened a new breakthrough. According to the “2010-2015 China Semiconductor Lighting (LED) Industry Investment Analysis and Forecast Report†released by China Investment Consulting, the total demand for crystal grains in the overall backlight market reached 48% in 2010, which means that the sapphire The substrate needs should be as high as 3.5 million. Each penetration of LED lighting by 1% will directly drive the growth of 1.07 million sapphire substrates. If the global penetration rate reaches 50%, an incremental demand for 53.5 million sapphire substrates will be formed. Zhang Yulin, research director of China Investment Consulting, pointed out that the demand in the downstream electronics market will become more and more intense. Such large-scale demand will prompt manufacturers to increase production capacity to meet market demand. However, due to the high barriers to entry in the industry, short-term supply is in short supply. Next, the price of the product will inevitably rise significantly. This has been reflected in the first half of 2010. Under the dual influence of rising prices and demand, existing manufacturers will obviously benefit.
