A high-brightness
LED CHIP device MOCVD (Metal Organic Chemical Vapor Deposition Equipment) was
successfully launched, representing the international advanced level, and breaking
American and European companies in this field in one fell swoop monopoly.
MOCVD machine is the most critical equipment in the production process of high-brightness LED chips. Due to the high technical difficulties, long development cycle, and late start of domestic industrialization, the market of led chip machine is mainly monopolized by European and American companies.
In recent years, since the penetration of high-brightness LED chips in outdoor led displays, backlighting of LCD panels, and automotive applications has continued to increase, especially in the semiconductor lighting market, the demand for mass-produced MOCVD equipments has shown an explosive growth. The annual demand reaches hundreds of units, and the market is worth billions of dollars.
China's LED epitaxial wafers and packages have achieved remarkable achievements in both scale and quality. The proportion of domestically produced products has increased significantly. However, key equipment, especially mass-produced MOCVD, still depends on imports. Production costs remain high, which severely restricts the LED industry. development of. Therefore, the development of a more cost-effective domestic commercial MOCVD equipment is an urgent requirement for LED epitaxial chip companies across the Taiwan Strait.
In September 2010, Ideal Energy started the MOCVD project. In two years, the ideal energy technology team designed and developed the MOCVD equipment with independent intellectual property rights, and completed the first generation of single-cavity independent equipment and high output rate. The production and assembly of the cluster production system successfully achieved the luminescence of GaN-based LED epitaxial wafers.
After nearly one year's operation of the equipment prototype, its performance has reached a predetermined target, and it passed the acceptance of the Shanghai Municipal Science and Technology Commission in May 2012. Based on the process validation results and customer feedback, the second-generation mass production MOCVD equipment was developed on the basis of the first-generation prototype. A single cavity can produce 84 2-inch wafers at a time, which exceeds the mainstream imported equipment.
The mass production models have been significantly improved in terms of output rate, reliability, and operating economy, and are most suitable for commercial mass production. The product has applied for 20 domestic and foreign patents.
