HC SemiTek Receives Aixtron Tools for LED Manufacture
China based firm HC SemiTek has received six CRIUS tools for manufacturing GaN LEDs at its Wuhan facility.
Aixtron has announced that HC Semitek placed an order for six additional CRIUS Gallium Nitride (GaN) epitaxial growth reactors. The six machines in the 31x2-inch wafer configuration have been delivered to the company’s modern facility in Wuhan.
With the rapid expansion of LED-based displays, backlighting and solid state illumination, manufacturers are choosing solutions that support flexibility and headroom to meet the diverse demands of volume applications.
According to Rong Liu, President of HC SemiTek, “The CRIUS enables significant operational flexibility and enhanced growth efficiency for state of the art UHB GaN LEDs. Our technology team is highly talented with a rich research experience gained from world leading research institutes. We now wish to extend our manufacturing capacity quickly and conveniently as per our strategic expansion roadmap for the displays environment. While this poses many challenges for providers – how to efficiently create precision epiwafers at very low cost – management through the responsive Aixtron support team will enable optimized process set-up without incurring project delay.”
The past year has been a boom year for MOCVD LED product development and manufacture, particularly in China. In addition to major companies testing the market for new business in areas such as residential lighting and mobile display applications, start-ups are making significant investments.
Lumileds to Lead LED Market for Automotive Lighting
Frost & Sullivan says Philips Lumileds’ products offer more lumens per Watt at a lower thermal resistance than those of competing LED suppliers.
Based on its recent analysis of the automotive light- emitting diodes (LED) market, Philips Lumileds has been awarded “2010 Global Frost & Sullivan Award for Technology Innovation of the Year”.
LEDs offer enhanced functionality to vehicle owners when compared to halogen, high-intensity discharge, and incandescent lighting systems. One of the primary benefits is its unlimited service life.
Unlike a filament bulb, the consumer never replaces it, unless the vehicle is involved in a collision. But the most attractive feature of LEDs is the ability to change color and brightness, giving vehicle designers the flexibility to develop mood lighting systems as a value-added feature to the car.
According to Frost & Sullivan, only three companies in the world have the technological capacity to produce automotive-grade LEDs that meet the exacting needs of vehicle manufacturers and their lighting suppliers. The firm thinks, that Philips Lumileds has done the most to advance the development of LEDs for motorists and the global auto industry.
Lumileds has two main LED product lines for automotive lighting. The LUXEON line is designed for high-power headlamps and daytime running lights. Its SnapLED and SuperFlux lines are red, red-orange, and amber LEDs used for taillights and signaling applications.
“The main differences between Philips Lumileds products and its main competitors are its Thin Film Flip Chip (TFFC) technology, which offers improved thermal handling and Lumiramic Phosphor technology which improves light quality,” says Frost & Sullivan Program Leader Stephen Spivey. “This represents a significant competitive advantage against the high-power devices of its two main competitors, particularly for the front of the vehicle, where the light requirements present the biggest challenges to lamp designers.”
