White LED demand `faces challenge of MOCVD tool backlog`
White light emitting diode (LED) demand will increase with the announcement by Apple of its iPad, placing pressure on their tight supply and backlog in the order of metal-organic chemical vapour deposition (MOCVD) tools, it has been claimed.
Analyst Munisamy Anandan, former president and managing member of Organic Lighting Technologies, commented on the Gerson Lehrman Group s website that many in the industry expected white LEDs to stay under the remit of solid state lighting, rather than being applied as backlighting for mobile telephones, notebooks and liquid crystal display televisions.
As such, there will be a shortage of supply of white LEDs in 2010, compounded by the backlog of MOCVD tools. He said that additional pressure will be placed upon the two major manufacturers of this equipment - Veeco Instruments and Aixtron.
However, Applied Materials has recently been awarded a grant by the US Department of Energy to advance epi tools for gallium nitride LED devices. An advanced multichamber hybrid epitaxial growth system will be developed, which will also be used for MOCVD.
This could help reduce the backlog in demand in the long term but may not help with the current situation.
Mr Anandan said the surge in white LED demand will benefit LED chip manufactures such as Osram Opto Semiconductors and Nichia.
The 13th CS International conference builds on the strengths of its predecessors, with around 40 leaders from industry and academia delivering presentations that fall within five key themes: Ultrafast Communication; Making Headway with the MicroLED; Taking the Power from Silicon, New Vectors for the VCSEL, and Ultra-wide Bandgap Devices.
Delegates attending these sessions will gain insight into device technology, find out about the current status and the roadmap for the compound semiconductor industry, and discover the latest advances in tools and processes that will drive up fab yields and throughputs.
