its subsidiary, GT Crystal Systems, has entered into a purchase agreement with Chongqing Silian Optoelectronics Science & Technology.
MOCVD tools processing two- and four-inch wafers. The large diameter cores will be produced from boules grown in GT›s ASF sapphire growth furnaces installed in the company›s newly expanded sapphire manufacturing facility in Salem, Massachusetts. This is the same technology which has been sold commercially to GT›s ASF equipment customers.
Soraa reveals its disruptive LED 2.0 technology
The firm’s LED MR16, built on its breakthrough gallium nitride on gallium nitride technology, is superior to halogen
GT’s ASF furnaces produce high quality sapphire crystal material that is well suited for LED manufacturing
«We are pleased to announce this important agreement for large diameter sapphire cores and to continue our long and successful relationship with Silian,» said Cheryl Diuguid, GT Advanced Technologies› vice president and general manager of its Sapphire Equipment and Materials Group.
«Silian has an outstanding reputation for providing high quality substrates to some of the most advanced LED producers in the industry. This contract further validates that sapphire material produced in our ASF furnaces is well suited for use in the LED supply chain.»
«ASF-grown sapphire has helped Silian and our customers to achieve the high yields necessary for the maturing LED industry,» said David Reid, COO and general manager, Chongqing Silian Optoelectronics Science & Technology. «The consistency and quality of ASF-grown sapphire has served our business well and we look forward to continued collaboration with GT Crystal Systems.»
The ability to produce LED-grade sapphire at diameters of six inches and larger helps to accelerate the transition to next generation MOCVD production tools capable of handling the larger diameter wafers.
Larger substrates allow more efficient MOCVD production processes than current generation
Soraa, a developer of GaN on GaN solid-state lighting technology, is launching its flagship product, the Soraa LED MR16 lamp.
The firm says this new product is the first LED lamp to provide superior performance to a traditional halogen MR16. It is also claimed to be the first LED lamp to provide halogen-equivalent brightness without requiring a mechanical fan and payback within months, not years.
The Soraa LED MR16 lamp based on GaN on GaN technology represents a revolutionary breakthrough in lighting technology: LED 2.0.
Founded by Shuji Nakamura, Steve DenBaars, and James Speck, Soraa leverages decades of expertise from the father of modern LED lighting, Shuji Nakamura, and preeminent solid-state lighting experts from the University of California, Santa Barbara. The company is headquartered in Fremont, California, where it houses the world’s first GaN on GaN light-chip fabrication facility and their lighting products design lab.
Soraa says its pure GaN crystal is up to one thousand times purer than GaN on sapphire or GaN on SiC substrates, the platforms other LED lighting technologies rely upon today.
“Our technological foundation enables Soraa products to emit more light per LED material and handle more electric current per area than competitors, providing the highest quality light that makes for a perfect, more energy efficient
