China growing trend of LED Chip in 2018
Since 2016, the LED industry has been in a period of rapid development, and by 2018, a new pattern has emerged. Looking at the entire LED industry chain, we can see that the LED chip field is a high-margin link in the LED industry chain.
Domestic major LED chip companies have successively expanded production, domestic LED chips will have the problem of excess capacity, chip prices will turn downwards, foreign LED chip makers tend to be cautious in expanding production, supply growth is limited, China's LED chip factory Ao'Yang Shun Chang, Huacan Optoelectronics, Sanan Optoelectronics, etc. rely on the support policies of local governments, and rely on the advantages of capital, scale, etc. to actively expand production, and global LED chip production capacity gradually shifts to mainland China.
2018 LED chip market size
In 2016, LED chip Epistar shut down 25% of the blue chip production capacity, the supply & demand relationship of LED chips changed. The LED chip industry started to pick up in the second half of 2016, with the outbreak of the small-pitch LED market in 2017 and the downstream packaging of LED chips. The expansion of the industry has led to a certain gap in the supply of LED chips. The utilization rate of LED chip companies in China has approached 100%, and the output value of China's LED chips has maintained a rapid growth.
The data shows that in 2017 China's LED chip (excluding Taiwan, the same below) industry output value reached 18.8 billion yuan(RMB or CNY, exchange rate approx. 1USD=6.35 Yuan), an increase of 29.7% from 2016, accounting for 40% of the global LED chip output value; MOCVD possession from China is more than 1,600 units, net increase of 246 units around the year, LED chip production capacity accounts for more than 54% of the world.
It is expected that by 2018, MOCVD machines in China will continue to increase by 288 units to 2,200 units. With the major expansion of domestic LED chip companies, domestic LED chips will suffer from overcapacity, and chip prices will shift downwards. The growth rate of domestic LED chip's output value will slow down. It is expected that China's LED chip output value will reach 22.5 billion yuan in 2018, a year-on-year increase of 19.7%. The top three companies in the market will have a capacity ratio of 47.8%.
LED chip prices gradually reduced-
After years of development, the price of LED chips has been reduced through the improvement of light efficiency. The cost of chip production is mainly variable and fixed cost. The variable cost includes about 65% of substrate, metal organic reaction source and gas, and the fixed cost includes depreciation and other about 35%.
The improvement of the manufacturer's technology brings about the improvement of the LED light efficiency. The number of chips that can be cut per unit area of the epitaxial wafer increases, the cost of the chip decreases, and the chip price also decreases year by year.
LED chip industry changes
According to statistics, the market size of China's LED chip industry in 2016 exceeded 14.5 billion yuan, an increase of 11.54% from the same period of last year. From the second half of 2016 to the end of 2017, prices have stabilized and rose steadily. With the increase in production capacity of Chinese mainland manufacturers, and the gap between technology and Taiwan is getting smaller and smaller, the advantages of price, delivery, and rapid market response are obvious, and the LED chip country's production rate increased from 50% to 80% in 2008-2016. It reached 10.6 billion yuan, while imports were 3.3 billion yuan. Due to the significant price/performance advantages of mainland chip manufacturers, the export ratio has also improved. The export rate in 2015 was 8.1%, and in 2016 it increased to 9.6%.
China's LED chip industry output value (100 million yuan)
The global market share of the top ten manufacturers increased from 66.1% in 2010 to 85.3% in 2017. China's LED chip production capacity is concentrated at Sanan Optoelectronics, Huacan Optoelectronics, and other leading companies. In addition to OSRAM still plans to expand production whereas no other manufacturers from foreign manufacturers have large-scale production plans. Most of China's domestic chip makers have been unable to expand production and gradually withdraw from production capacity competition. Although Megachip has launched a new LED chip project, its impact on the market in the short term is still very limited.
Increased concentration of production capacity at the mainland chip factory-
LED chip industry development trend
In recent years, due to government policy support and R&D capital intensive investment in China, and accompanied by a large number of Chinese Taiwanese and South Korean LED industry technical experts and teams joining local companies, the average technical level of domestic LED epitaxial chip companies has made considerable progress and has achieved International advanced level.
Reducing the cost of epitaxy and chips is crucial for promoting LED applications. In recent years, researchers have started with new technologies, new structures, and new processes. Through technological innovation, they have continuously reduced the costs of epitaxy and chip production. The cost of white LED packaging will be reduced from US$25/klm in 2009 to US$0.7/klm in 2020, with the ultimate goal of LED cost being US$0.5/klm, and the average annual cost will drop by more than 30%.
In addition to luminous efficiency and unit cost, in LED display screens, backlights and other applications, the LED chip's light decay, brightness, color consistency and anti-static capabilities are also key technical indicators related to LED applications.
Although the expansion rate of several large manufacturers is surprising, the overall capacity expansion rate is relatively limited (145%). Considering that new machines such as Veeco's Red Bull, A7 micro- and A6 and some Axitron's R6 have become new machines. After the main model, K465i, CRUIS2 and earlier models gradually exit from the market, the overall market supply was more concentrated, and the capacity increase was also lower than expected.
In addition, subsidies for local government MOCVD equipment are relatively more concentrated. Differing from the pattern of early equal division, local governments are now more inclined to select companies with subsidies that have demonstrated good operational and management capabilities in the market economy.
The strength of the subsidy also needs to be determined according to the mode of one-on-one negotiation according to the company's strength and negotiating ability. Companies with advantageous industry status and good tax paying ability are in a more favorable position in bargaining with local governments.
From the supply structure point of view, because the expansion progress and margins of Sanan from 2017 to 2018 is only slightly higher than the expansion rate of the entire industry, compared to the fact that the absolute amount of expansion is not small, but relatively compared to Huacan and Aoyang, the expansion operation appeared too conservative.
The supply structure of the LED chip industry has lost the opportunity to transform into a structure similar to that of the semiconductor foundry industry, and may gradually form a three-legged structure similar to the DRAM memory industry. In contrast, assuming that CR3 is equal, the three-legged structure lacks stability, and its competitive strength is higher than that of a super strong one and is also higher than that of a duopoly structure.
With an industry profit of nearly 75%, Sanan, an industry leader, has the power to sacrifice some of its profitability to operate its production deterrence strategy, forcing back potential entrants (Zhao Chi) and compelling its competitors (Hua Chan, Aoyang Shunchang) to be more cautious to expand.
Although the big oligarchs in the LED chip industry will not be openly enough to jointly allocate output by a formal agreement, the increasingly high industry concentration and the demand price elasticity of LED chips will force companies to reach a tacit understanding and take the initiative to limit the production in order to keep price.

The degree of understanding and cooperation between the three oligarchs will become the key factor in determining the price trend of LED chips in 2018. However, the three oligopolistic structures have natural instability, and new game models are still in forming.
