Aixtron AG: Latest developments and future trends in MOCVD technology

Topic: Industry Aixtron AG is the world's largest and most marketed LED equipment supplier. Recently, Mr. Michael Heuken, Vice President of R&D of Aixtron AG, gave a brief description of the latest developments in MOCVD technology and future technology trends.

It is understood that Ai Siqiang mixes large-size and multi-chip MOCVD equipment, and the market share of LED equipment has reached 70%. Ai Siqiang is the world's largest supplier of MOCVD equipment, with great research and development. center. Then, what is the mainstream direction of Ai Siqiang's future equipment? For LED manufacturing, the most obvious key challenge at present is still to reduce the cost per lumen and improve the efficiency of LEDs. Michael Heuken said that the cost of LEDs should be measured from the entire life. From the perspective of each device usage, Ai Siqiang will use various possibilities to reduce LED costs, including epitaxial wafer cost and packaging cost, while equipment and packaging. The cost will be high, and the cost of the epitaxial film is relatively low, only a small part of the overall cost. At the same time, Ai Siqiang will help LED manufacturers to reduce costs. From the perspective of the whole strategy, Ai Siqiang's research and development direction is of course a large-scale epitaxial wafer, and there are also many slices.

In the latest advances in MOCVD technology, Michael Heuken said that the company's MOCVD system is based on two unique technologies: Planetary Reactor® and Close Coupled Showerhead® (CCS®), both of which offer high throughput rates. Excellent consistency and process repeatability to achieve high yield and high cost of ownership. Both technologies are implemented on a common platform, giving users greater flexibility and scalability. The company's MOCVD system has a wide range of size epitaxial wafer processing capabilities, from 2?, 3?, 4?, 6?, 8? or even 12?, to meet the customer's constant pursuit of lower manufacturing costs. In addition, Ai Siqiang is also based on some other attractive new technologies. Taking OVPD (organic vapor deposition) technology as an example, OLED is expected to play an important role in the future solid-state lighting field once some key performance indicators such as luminous efficiency and lifetime can be achieved. Michael Heuken said that in the future, the company's research and development strategy will closely follow the market demand and translate the expected technical requirements into the technical goals of the MOCVD R&D team.

At this stage, Ai Siqiang has many competitive advantages in MOCVD technology. Michael Heuken said that, first of all, Ai Siqiang's core competitiveness and strength lies in the technology and equipment needed to provide complex vapor deposition processes. Different strategies, differentiating and different maturity technologies will be adopted for different end markets. . Secondly, Ai Siqiang has sufficient production equipment to meet the huge market demand of MOCVD at this stage. The LED market is becoming more mature, so Ai Siqiang pays more attention to cost and productivity improvements. As the initial technical barriers were gradually eliminated, the industry focus shifted to cost and productivity. In addition, Ai Siqiang is committed to solving customer needs and actively analyzing future market trends in order to consolidate the position of the world's leading manufacturer.

Michael Heuken pointed out that it can be said that it is an excellent opportunity to expand the LED industry. China and Taiwan are very important markets. The development of the LED industry is very important to the country, the company and the environment. While creating profits, it can also bring benefits to the company. LEDs are not only green energy-saving products, but also can create huge profits in this field. Therefore, in this important period, it is necessary to develop LED technology in China.
