MERRIMACK, USA: GT Advanced Technologies Inc. announced that OCI Co. Ltd, its long-time South Korea-based PV and now also a sapphire equipment customer, has begun production of sapphire boules and cores in its new manufacturing facility. The company has completed the initial installation of GT’s ASF sapphire growth furnaces that were purchased in January 2011.
In a ceremony on March 2 to commemorate its new sapphire production facility, OCI mentioned it has begun the shipment of 6-inch sapphire cores as well as 2-inch and 4-inch products to top manufacturers located in Taiwan and Korea. The new eco-friendly plant has an annual production capacity of 4 million millimeters of sapphire.
“Starting up a new sapphire production facility takes tremendous planning and coordination to ensure a successful launch,” said Cheryl Diuguid, GT Advanced Technologies’ VP and GM, Sapphire Equipment and Materials Group. “I am proud of the effort of our service and installation team who worked closely with OCI’s production and engineering team throughout the entire process to deliver a state-of-the-art sapphire production facility that is now producing high quality material.”
OCI’s ability to produce LED-grade sapphire at diameters up to six inches will help to position them as a top sapphire producer in the region. Their entrance into the LED industry utilizing GT’s ASF sapphire growth technology expands the relationship between the two companies. OCI and GT have successfully partnered together for a number of years in the PV industry where OCI has quickly grown to become one of that industry’s top polysilicon producers.
