  LED chip, a solid state semiconductor devices, LED is the heart of a semiconductor chip, the chip is attached to one end of a stent, one end is negative, the other end is connected with the power supply of the cathode, the entire chip package to be epoxy resin.

Also known as LED light-emitting chip, is the core component of LED lights, that is, P-N junction. Its main function is to convert electric energy into light energy, and the main material of the chip is monocrystalline silicon. Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a P-N junction between them. When the current passes through the wire acting on the chip, the electrons are pushed into the P region. In the P region, electrons combine with the hole and then emit energy in the form of photons, which is the principle of LED luminescence. The wavelength of light, that is, the color of light, is determined by the material that forms the P-N junction.

  LED chip industry as an important part of LED industry chain, its performance directly determines the development of LED industry. At present, the domestic lighting power type LED chip products have made great progress in the light effect, life and reliability, to develop graphics substrate, a transparent electrode and a full range of mirrors and a series of key technology. Domestic chips are expected to gradually penetrate and eventually replace imported chips by virtue of their superior performance and competitive price advantages.

At present, China's LED chip industry mainly formed by three safety optoelectronics, HC semitek, Elec-Tech, Tongfang, Australia Shunchang, changelight and other major chip manufacturers dominated the supply chain; at the same time, along with the silicon substrate LED technology has made breakthrough progress in latticepower as the representative of the new chip companies is expected to. In recent years, due to the "price war" and "crazy expansion" of vicious competition, the upstream chip prices have repeatedly bottom. In 2016, LED industry to pick up and slow capacity expansion rate, crystal power, chip manufacturers have three price, lead the LED industry pending another round of "price boom".
In 2017, the concentration of LED industry has been further improved, and the industry competition has become more rational. The major LED chip enterprises are moving towards a different way of development. What are the routines for the development of chip enterprises in China?
1, adjust the product line, founding the new application
The blue LED competition, with crystal power, light, Hong Hua upper Taiwan based LED chip business to the transformation of the road, four yuan LED has become one of the direction of its transformation. At the end of last year, four yuan revenue climbed above the record of LED, not only the blue LED dilution proportion, also has international visibility, to help manufacturers improve price protection ability; crystal electric last season has lift to 25 ~ 30百分比, if this season quaternion LED maintains a high visibility, do not rule out the light hung 50百分比 continue to move up; to four yuan China is full; turn into four yuan LED.
Taiwan factory LED pointed out that Japan and South Korea in the four yuan LED almost no manufacturer, with a small amount of an optoelectronic machine, however, industry characteristics of four yuan LED do not take large amount of standard specifications, with phosphorus, arsenic and other chemical substances involved in environmental issues, plus the mainland audit will tend to be strict, not logical is the national support for the project, so China manufacturers in Taiwan turned into a four yuan LED relative odds.
The industry said, when the mobile phone terminal demand with the connection of iris recognition, night vision function, and automatic driving, four yuan LED, the price is better than laser light in the light angle; the long term, although Micro LED is still in development, but the future is also one of the kinetic energy of red LED.
In addition, Micro LED is also the main direction of the major Taiwanese chip enterprises. Micro light emitting diode (Micro LED) is expected to become a new generation of display technology, Taiwan factory such as LED crystal power plant, are actively involved in the hope of Luanda, accelerate the commercial production process. Taiwan ITRI optimistic forecast by Micro LED in 2017, large-scale public display will debut.
"Because of the small size of the Micro LED, the epitaxial crystallization of the crystal and the process of grain fabrication should be developed in conjunction with the transfer equipment and system applications," said Zhang Shixian, spokesman for crystalline silicon. In the process of epitaxy and grain, MicroLED has a high probability of success. As for next year's production, it will be very hard.
Zhang Shixian said, Micro LED need to have good technology, patent capabilities, and in conjunction with materials, equipment, systems and factories jointly developed, the threshold is high, especially red LED. Crystal has an advantage in killer applications.
Lextar chairman Su Fengzheng said, Micro LED is a new technology, new applications, have the opportunity to increase the amount of use of LED, which is one of the direction of the layout of the new application of luanda. At present, many companies are in the layout, progress varies. As for when commercial production, he believes that the initial investment rate of poor, more people to invest in the yield after the promotion of the learning curve can not be omitted. Generation after generation of new technology is always ready, ronda.
Of course, the car LED is also the focus of many chip manufacturers. Vehicle LED lighting is one of the most popular applications in LED market. Countries have benefited from through environmental regulations to require gasoline vehicles to improve fuel consumption, and the trend of hybrid electric vehicles, electric vehicles and actively introducing new technology, plus the electronic development, a new field of automotive LED lighting has become many manufacturers to actively research, development and preparation.
Crystal electric R & D center Xu Jialiang associate pointed out that car LED lighting has matured, there will be more new applications, such as situational lighting and head up display; car LED lighting technology has gradually put in place, awaiting departure. For example, the headlight group, night vision systems and ADAS advanced driving assistance systems, etc., will use white LED, IR, LED and LD components, which are global LED manufacturers, can not be ignored new blue ocean. In Europe, with the mandatory mandatory day lights (DRL) on the road, LED lights have gradually jumped out of the relatively mature steering lights, taillights. Due to market demand expansion, and manufacturers mature technology, cost and yield optimization, and the car factory verification time is enough, so that LED light source can further into the car outside the lamp market, will be able to make great contribution to revenue.
2, capacity expansion, to seize market share
A few years ago, LED lighting industry crazy expansion, market demand is too saturated, serious overcapacity lead to price wars and industry reshuffle, a number of LED companies in 2015 losses. With the LED market to pick up, LED epitaxial chip prices have stabilized. 新葡的京集团3522vip

  In January 9, 2016, three optical announcement that the net proceeds of 3 billion 454 million yuan. Among them, 1 billion 910 million yuan for Xiamen Sanan optoelectronics industrialization (two) construction project ". Xiamen photoelectric industry (phase two) project with a total investment of 3 billion 645 million 100 thousand yuan, construction period of 24 months, mainly engaged in LED epitaxial wafer and chip production. At present, an optoelectronic domestic market share of about 30百分比, the company expects expansion in 2017 33百分比, the end of the year up to 2 million / month, expected revenues will exceed the size of crystal electric, become the leading international LED chip.

Similarly, Hua Guang photoelectric in the expansion of the road is not inferior. In 2016, China invested 6 billion yuan to expand its production. It was put into operation in July 2017 at the new plant in Yiwu and will reach an annual output of 3 million LED chips. Hua Guang photoelectric as a small distance LED chip leader will benefit and expand, is expected to achieve by the end of 2017 LED chip 1 million 400 thousand / month production scale, reaching second of the country, the world's top scale.
In May 15th this year, the disclosure, the Commission received non-public offering of not more than 368 million shares approved the company intends to raise funds not more than 2 billion yuan total, will invest LED flip chip, LED chip scale package project. Among them, the LED flip chip project with a total investment of 2 billion 500 million yuan, intends to use fund-raising 1 billion 500 million yuan, is expected to form an annual output of flip chip 5 billion production capacity.
Xiamen dry shine photoelectric in May 5th passed the "main business expansion of the company's motion.". In 2017, red, yellow, LED epitaxial wafers and chips will continue to benefit from the continued growth of small screen display areas. The expansion project has a total investment of 737 million yuan, which is used to expand the production of red and yellow LED chips and three junction GaAs solar cells. The main equipment is 20 sets of four yuan MOCVD epitaxial furnace and the corresponding chip production equipment.
Australia Shunchang LED chip as the lighting chip, the existing capacity of 200 thousand / month, 2016 production 2 million 50 thousand, 2 million 540 thousand sales. New production capacity of 60 / month, is expected to start climbing in the two quarter, the end of the two quarter can be full production, 2017 of the production capacity can reach 750-800 million. In December 2016, Australia Shunchang in cooperation with the domestic leading enterprises to promote LED LED packaging wood Linsen, two expansion plan.
This year, Siu Chi shares have also joined the LED chip industry. June 30th, Siu Chi shares issued a notice, the company will invest not less than 1 billion 500 million yuan, and not higher than 1 billion 600 million yuan, in Nanchang High-tech Industrial Development Zone Investment in building LED epitaxial chip and chip production projects.
Last year, due to many small chip companies due to competition lack of ability to exit the stage, because the past two chip companies for market expansion and even conservative, slow down the pace of production, LED chip production capacity last year led to the lack of preparation. This year, LED chip due to tight production caused by several rounds of price increases, so that these scale more pre - chip enterprises to accelerate production pace.
3, the acquisition of mergers and acquisitions to achieve diversification
As a simple and fast way of development, M & A has been pushed by many capital LED companies. Through mergers and acquisitions, some enterprises in the vertical expansion, LED layout of the whole industry chain; some enterprises have entered a new industry; more enterprises through mergers and acquisitions overseas companies to go abroad, to the world. In the field of LED chips, many chip enterprises through mergers and acquisitions to achieve diversified development.

 Although a few days ago, China Optoelectronics released a merger on the suspension of harmony light, but said it will still start the transaction at the right time. Huacan in recent years has acquired Yunnan langene Technology (completed), MEMSIC semiconductor (in progress), focusing on its acquisition of cutting-edge technology industries and industrial chain collaboration, the future will continue to promote international cooperation and mergers and acquisitions.

Huacan chairman Yu Xinhua said that the synergy effect of LED and the main value of MEMSIC semiconductor sensor industry, and focus on the layout of LiFi (visible light communication industry). The cumulative shipments of more than 1 billion kinds of MEMS MEMSIC semiconductor sensor, its application fields include consumer electronics, automotive electronics and industrial control. As a key component of safety airbag, new high precision accelerometer downstream customers include Ford, GM, BMW, Benz, Microsoft, etc.. M & a new semiconductor, contribute to the promotion of LED products to enter the automotive industry supply chain.
The same Sanan Optoelectronics Market is more active in mergers and acquisitions. Before, an optoelectronic wholly owned subsidiary of Xiamen Sanan integrated circuit Co. Ltd. according to the laws of the Cayman Islands to set up a wholly owned subsidiary of its own monetary funds at $226 million (about 1 billion 502 million yuan) to buy GCS HOLDINGS INC.100百分比 stake. This acquisition has failed to get through the Committee on foreign investment approval, but three determination to seek diversified development pace did not stop there. Last year, also once heard an optoelectronic to buy OSRAM news, after once clarification is only the preliminary contact, but from which we can see the ambition and ambition of the Sanan optoelectronics.
4, powerful combination, all-round layout
If you say that an industry is a business can not be determined, then a number of enterprises to join forces to get together, LED industry is also true. Powerful alliances, especially in the upper and lower reaches of the industry chain, have become "more sought after" development models.

  As NVC and Elec-Tech Chinese lighting industry leader LED whole industry chain, this combination had remarkable. One is the lighting industry channel and brand leader, is a leading source of the upstream chip and NVC through the cross holding Elec-Tech form, develop downstream cooperation; and through the Australia Shunchang Linsen joint venture subsidiaries to carry out cooperation; to establish a joint venture with CREE optoelectronics, the main power LED packaging products; MLS and HC semitek signed a "strategic cooperation agreement, mutual benefit and achieve win-win goal, establish strategic cooperative partnership and so on.

The implementation of large enterprises and enterprise groups between the "strong alliance", especially the formation of trans regional, cross industry, cross ownership and transnational operations of large companies and large enterprise groups, can achieve complementary advantages, optimize the allocation of resources, reduce production costs, improve labor productivity, promote research and development of the cash constraint, to expand market share the amount and obtain more economic benefits.
