Application manufacturers forced the upstream of the cost of silicon-based GaN into a weapon
In this regard, Veeco's executive vice president of compound semiconductor business William J. Miller said: "Veeco was selected as Samsung SAIT to study silicon gallium nitride, and commercialized this technology for mass production of GaN power devices, we believe that A huge strategic R&D victory."
LED application manufacturers force upstream to reduce costs
The latest research report of Nomura Securities reduced the investment rating of LED packaging factory Yiguang (2393) from "neutral" to "subtraction". Nomura pointed out that LED light packaging factories such as Yiguang will be the main victims of LCD panel manufacturers seeking to reduce production costs this year; it is estimated that the revenue growth rate in 2011-12 will be only 12-14%, and the gross profit margin is expected to drop to 20%. -25%.
Silicon GaN is the next step to reduce LED cost
On March 25th, Bridgelux (Purray Optoelectronics), a US investment in VTAF, a subsidiary of TSMC (2330), officially announced that it has achieved the use of GaN-On-Silicon LED technology. 135 lumens per watt. This means that Bridgelux has become the industry's first manufacturer to achieve commercial grade performance in silicon semiconductor substrate LED technology.
According to the Bridgelux study, the performance of silicon-on-silicon LEDs is comparable to the top-of-the-line sapphire substrate LEDs introduced 12 to 24 months ago. It is estimated that in the next two to three years, GaN-on-silicon LED products used in the commercial market will be available for sale.
At the same time, Bridgelux also believes that the cost of LED epitaxial products is expected to be greater if existing gallium nitride is formed on larger diameter, lower cost silicon wafers and processes compatible with modern semiconductor production lines. The process is effectively reduced by 75%.
Semi-harvester for Agriculture:
The semi-feeding harvester can complete the harvesting, delamination, separation of stems, removal of sundries and other processes at one time, and the Rice Harvester machine for obtaining grain directly from the field is mainly suitable for rice harvesting, wheat harvesting, and this reaper machine can adapt to deep mud feet. Under the serious harvest conditions, the grain cleanliness after harvest is very high, and at the same time, the stem integrity after harvest can be guaranteed, so that farmers can complete harvesting and granulation with a single operation, thus saving manpower and material resources and greatly reducing the burden of farmers.
Semi-harvester for Agriculture Technical Parameters:
1. Size: 3650*1800*1820 (mm)
2. Weight: 1480KG
