Sapphire Substrates for LED: The big move toward 6" has already started
Live Webcast on Thursday, July 28, 2011 at 8:00 AM PDT
LEDs have already reached a sufficient price/performance level to enable massive adoption in LCD display applications. General lighting application will be the next and largest market for LED light sources. However, for most of the applications, LEDs are still too expensive. The industry consensus points toward the need for an additional 10x reduction in packaged LED cost of ownership expressed in $/lumen in order to compete broadly with incumbent technologies and enable massive adoption in most lighting application segments. To answer this demand, huge efforts have to be made all over the value chain, from the sapphire substrate to the final luminaire cost structure. Increasing the substrate diameter is one of these enabling technologies. 2009 saw the introduction of first industrial tools running 6” diameter for LED manufacture and this industry is now clearly moving toward larger substrate diameter. C-plan 3” and 4” already represent about 50% of the total surface shipped in 2011 and 6” is now reaching 5% of the production, thanks to companies such as LG, Samsung, Showa Denko, Osram or Lumileds who all moved to 6”.
