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.

2V Battery Pulse Restore System fully take into account the inconsistent of the physical resonance frequency between lead sulfate crystal and battery plates, select the optimal frequency of pulse waveform and pulse current intensity to "break" and "decompose" the lead sulfate crystals, ensure the best restoration effect of sulfide battery without any damage to the plates.
Off-line 2V Battery Smart Pulse Restore System, also be called  Battery Reconditioner or Battery pulse maintainer and  Reviver: mainly used in the whole industry of Electric Forklift power battery, Sightseeing car power battery, Golf Cart battery, Wind and Solar energy storage battery, UPS Back up power system, Telecom base site battery, State Grid and Military battery for Sudden affair,etc.
The system is composed of 3 parts and a professional standard restore process: 1) 2V Battery Restorer Device(100~3000Ah); 2) 2V Battery Digital Pulse Charger; 3) 2V Battery Discharge Tester.  Lead-Acid Battery Restoration system and Solution is applicable to all of Lead Acid Battery(AGM, GEL, VRLA, MF, Flooded, Dry, Traction, Deep cycle and Stationary), and widly used in 2V (200~3000Ah) cell batteries. 

Product features
1.  The smart pulse with fast rising front is resonant with the crystal of lead sulfate to dissolve the large lead sulfate crystal under the action of charging pulse, which can improve the capacity and prolong the service life of the battery.
2.  No need to add any chemical additives, does not change the internal electrolyte composition of the battery, safe and reliable; For water loss batteries only need to add deionized water before restoring. The output pulse voltage and pulse current are strictly limited.
3.  12 independent output, can repair 12PCS 2V/100Ah-3000Ah cells at the same time without interference. Each group is equipped with a separate voltmeter to monitor the voltage of the repaired battery in real time.
4.  Each system is equipped with "capacity selection" gear, according to the different capacity of the battery to select the appropriate gear, can be ensure better protection of battery plate in restore working.
5.  Each system is provided with automatic repair function, automatic repair system will smartly adjust the pulse duty ratio based on the receptivity of the battery without anyone on duty
6.  Each system is equipped with "High resistance repair" function, select the high resistance repair, specially for the long term stored batteries, even if the OCV is 0 Volt, but also can be easily activated.
