Now OCI says it is looking to capture a 20% share of the global ingot market by 2015 and to emerge as one of the world’s top 3 ingot providers.
OCI CG Business planning team leader Yang Jae-yong concludes, “After pilot operation at the end of last year, the mass production has been put in place, and the product has passed the sample tests of the world’s leading wafer manufacturers. We will focus on 6-inch ingot, a high value- added product, and try to increase consumer satisfaction and secure competitiveness in the global market.”

efforts escalate TriQuint, Mitsubishi Electric, Nitronex, RFMD and Cree are among the companies announcing new developments on GaN devices
As products using GaN technology continue to gain acceptance in military and commercial applications, development activities at microelectronics companies are accelerating.
GT’s ASF sapphire growth furnace which utilises HEM for producing high quality boules and cores suitable for the LED industry and other industries requiring high quality material
A recent article in The Korean Times reported that GT’s ASF furnaces, which use the Heat Exchanger Method (HEM) growth process, incorporate a cost-effective sapphire crystallisation methodology for the high yield production of quality material.
HEM, was initially developed in the US to produce 8” - 12” single-crystal sapphire in 1971. OCI says it is different from other methods as the single-crystal sapphire ingots grow from bottom to top. What’s more, HEM produces large diameter single crystals with precise control over the temperature gradient.
“Starting up a new sapphire production facility takes tremendous planning and coordination to ensure a successful launch,” notes Cheryl Diuguid, GT Advanced Technologies’ vice president and general manager of its 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 says its ability to produce LED-grade sapphire at diameters of up to six inches will help to position it as a top sapphire producer in the region. The company’s entrance into the LED industry using 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.

The Strategy Analytics GaAs and Compound Semiconductor Technologies Service (GaAs) viewpoint, “Compound Semiconductor Industry Review October-December 2011: Microelectronics,” captures product, technology, contract and financial announcements for companies such as RFMD, Skyworks, Fujitsu, Anadigics, Agilent, Hittite Microwave, TriQuint, Avago, NXP Semiconductors, Microsemi, Renesas Electronics, Freescale, Broadcom, Cree and Murata Manufacturing.
“GaN-based products have demonstrated performance advantages for military systems for some time and they are finally beginning to see acceptance in commercial applications, such as CATV and wireless infrastructure,” notes Eric Higham, Director of the Strategy Analytics GaAs and Compound Semiconductor Technologies Service. “As these application areas broaden, the industry is responding by increasing their efforts to develop new products, processes and partnerships.”
Asif Anwar, Director, Strategy Analytics Strategic Technologies Practice, adds, “Recent announcements indicate growing interest in GaN-on-Silicon processing to reduce cost and higher voltage GaN processes, which will improve power handling performance.”
The October - December quarter of 2011 saw mostly positive revenue reports from microelectronic companies, with Skyworks cementing its position as the leading GaAs device manufacturer. Companies continue to diversify through reorganisation, partnerships and product development aimed at adjacent and high performance market applications. GaN development activity continues strongly with several foundry and product announcements.
In the report, Strategy Analytics has summarised financial, product, contract and employment developments from leading compound semiconductor device suppliers in Q4 2011. These announcements address a variety of commercial
