LED Epitaxial Chip Industry Development in 2012

International LED Epitaxial Chip Industry Development Status LED epitaxial growth and chip manufacturing links have a high technological content in the LED industry chain, a large investment in equipment, and a relatively high profit margin. They are typical capital and technology-intensive industries and their technologies and development. The level has a decisive influence on the LED industry structure of each country and the market position of each company. In recent years, driven by the downstream demand, the penetration of LED in the backlight, lighting and other fields will continue to increase. According to the National Semiconductor Lighting Research and Development and Industry Alliance statistics, the global LED chip demand in 2008 was converted to 23.6-inch wafers per month, up to 2.01 million chips per month by 2010, and the compound annual growth rate was reached during this period. 65%, its forecast, by 2015, the total demand for LED chips equivalent to 2 inches of epitaxial wafers will reach 18.75 million / month, about 9 times in 2010.

Development status of domestic LED epitaxial wafer industry China's LED industry has started to develop from packaging. The initial chip relied mainly on imports. In recent years, driven by the strong demand in the downstream and supported by local policies, major LED epitaxial chip companies in China have increased investment in R&D, and actively formulated With regard to the expansion plan, the market's investment in the epitaxial chip segment will continue to increase, which will accelerate the development of the domestic LED epitaxial chip industry. By 2011, the localization rate of domestic chips has reached 70%. According to statistics of National Semiconductor Lighting Engineering R&D and Industry Alliance, the overall market size of China's LED epitaxial chip industry was approximately 2.3 billion yuan in 2009, and it has risen to 6.5 billion yuan in 2011, with a compound annual growth rate of 68.11%.

According to the National Semiconductor Lighting Research and Development and Industry Alliance statistics, the domestic demand for LED chips was reduced to 490,000 pieces/month in 2010, which is a 48% increase from the same period of last year. It predicts that domestic demand for LED chips for display will increase in the next five years. The trend of steady growth will continue to be maintained. With the further increase in the penetration rate of backlight sources and the start of lighting applications, the demand for domestic LED epitaxial chips will increase substantially. By 2015, the domestic demand for LED chips will be equivalent to 2 inches of epitaxial wafers. It reached 5.55 million tablets/month, about 11 times that of 2010.

In 2012, barriers to entry in the LED epitaxial wafer industry 1. Technical barriers to LED epitaxial growth and chip manufacturing processes require a number of specialized technologies involving optical, electrical, materials science, surface physics, inspection technology, lithography and other multi-disciplinary knowledge, and There are more than one hundred process parameters that need to be controlled in the production process such as physical analysis, structural design, parameter setting, and equipment control. This requires not only profound theoretical knowledge, but also long-term experimental testing and mass experiments. Data as a basis. Especially in the LED epitaxial growth process, the MOCVD equipment needs to be accurately matched with the epitaxial growth technology in the setting of the temperature zone, the adjustment of the temperature-changing transformation process, the growth rate control, the degree of automation, the ratio of the carrier gas and the gas source, and each MOCVD apparatus. Due to the inherent differences in process parameters, there is a need for long-term production experience as a guide, which places high requirements on the technical background and operational experience of technical personnel. Therefore, it is difficult for newly entering enterprises to carry out mass production of LED epitaxial wafers and chips in a short period of time.

2. Process management barrier LED epitaxial growth and chip manufacturing process belong to the fine production process and require strict process management and production control. LED downstream products have high requirements on the production yield of the chips. In mass production, a small number of chips will cause the entire end product to be scrapped. Therefore, higher requirements are placed on the stability of the LED chips. It is necessary to accumulate long-term and large-scale production experience to ensure the stable quality of the chip while ensuring large-scale production and to effectively control the cost of the process flow management. Therefore, product manufacturing process management will become a major obstacle for new entry companies.

3, scale barriers LED epitaxy chip industry early investment, product fixed cost is high, the need to form a scale advantage, improve equipment utilization efficiency in order to effectively control costs and strengthen the competitiveness of enterprises. At the same time, the downstream packaging companies generally hope that the selected chip suppliers can fully match their capacity requirements to ensure the stability and consistency of the purchased chip products. Therefore, only the outsourcing chip manufacturers with scale production capacity can establish large downstream customers. A stable cooperative relationship. Newly-entered companies lack the experience of large-scale production management, and it is difficult to form advantages in terms of cost and scale in a short period of time, thus constituting an entry barrier.

4, brand barriers LED chip quality is the key factor in determining the LED terminal products, so downstream manufacturers of LED chip suppliers to provide high reliability and stability of the product, LED chip products usually require more than half of the certification process before they can be Downstream vendors accept it, and downstream vendors choose a supplier to develop a certain degree of stability and continuity, usually not easily changed. Existing mainstream epitaxial chip manufacturers have a good brand reputation, and through the establishment of long-term relationship with downstream manufacturers to ensure a stable relationship between supply and marketing, new companies must be able to provide stable and mass-produced chips for a long time to obtain downstream Manufacturer's approval. Therefore, in the fierce market competition, LED epitaxial chip manufacturers' brand and market reputation form a certain barrier for new entrants.

5, capital barriers LED epitaxial growth and chip production requires the purchase of expensive and advanced production equipment, and each manufacturing process involves many processes, all require professional and even customized equipment and test equipment. For example, the MOCVD equipment used for epitaxial growth needs to be sold at a price of RMB 10 to 20 million each, plus auxiliary equipment, clean workshops, etc. The establishment of a large-scale LED epitaxial wafer production line usually requires several hundred million yuan, and therefore capital entry barriers. Higher. In addition, LED epitaxial chip industry as an emerging high-tech industry, technology advances day by day, the company needs continuous large-scale investment in R & D to ensure technology updates and product upgrades, thus consolidating the company's competitiveness in the market. As a result, LED epitaxial wafers and chips require large capital investment, which also poses a high barrier to new entrants in the industry.

Under the AC system series, we have two different waves system, modifed sine wave and pure sine wave. The pure sine wave AC system is more stable, but the Modified Sine Wave system will has cheaper price and smaller size. Use series connection PWM charge circuit. Charge efficiency is 3%-6% higher than witnout PWM, gives longer life to products.
