Monocrystal Advances into the Land of 8-inch Sapphire
Leading global LED manufacturers are moving towards 8” sapphire substrates to make their devices.
Russian firm, Monocrystal, a manufacturer of electronic materials for LED and solar industries, is shipping its premium 8-inch C-plane epi-ready sapphire substrates to one of the world’s leading LED manufacturers.
In the past, LED industry players and experts have discussed the possibilities for the industry of employing larger than 2-inch sapphire substrates for LED production. The discussion revolved mainly around advantages and benefits of switching to 3- vs 4-inch substrates. Then, the use of 6-inch sapphire substrates appeared to be quite a remote prospect and any discussions of the 8-inch substrate opportunity became mostly a theoretical exercise.
However, Monocrystal says the world's leading manufacturers who are currently producing LEDs on 6-inch sapphire substrates are beginning to approach 8-inch substrates as well.
“It took leading LED manufacturers three years after the 6-inch sapphire substrates first became available on the market to launch R&D on their use for LED production. The period was shorter for the 8-inch substrates – Monocrystal was the first to introduce and ship them to a MOCVD system manufacturer in August, 2008, and approximately two years later, we have supplied our premium 8-inch C-plane epi-ready sapphire substrates for the R&D use at the forefront of LED manufacturing. The market dynamics in the LED space indicate a further shift toward the use of the larger diameter substrates, as well as the growing role of the suppliers, capable of meeting the high technology standards of the today's LED market,” said Oleg Kachalov, CEO of Monocrystal.
“Monocrystal has been supplying 8-inch sapphire substrates for the R&D on RFIC applications for the last two years, and we have gained considerable experience in large diameter sapphire substrates production. We are glad to be able now to support also our LED customers in making a technological breakthrough which will help bring forth the widespread use of the LED lighting,” added Mikhail Berest, VP Sales & Marketing of Monocrystal.
