With a glut of GaAs capacity still in place, how can pure-play GaAs foundries survive and be profitable? Not easily, in the view of some senior industry figures. Michael Hatcher catches up with WIN Semiconductor and reports on what some see as a flawed business model.
As the market-share leader in cellular power amplifiers, RF Micro Devices continues to implement new technologies and introduce smaller and more highly integrated products. The company is now set to potentially double its dollar content within each handset by moving into the GSM/GPRS transceiver market. Compound Semiconductor spoke with Jerry Neal, RFMD co-founder and executive vice-president of marketing and strategic development.
Buoyant sales of DVD players and recorders in 2003 more than offset the third consecutive annual drop in sales to telecom applications as the laser diode market grew for the first time since 2000. Figures show that optical data storage is now dominating the laser diode market more than ever.
At the annual OFC conference in late February, members of a mildly optimistic fiber-optic industry gathered in Los Angeles to discuss the latest developments in what could be the start of a recovery for the depressed sector. Michael Hatcher reports.
A unique combination of self-organized quantum dot structures, an AlAs-GaAs material system and a defect-reduction technique promises to deliver dramatic advantages for GaAs-based devices in both optoelectronic and microelectronic applications, writes Nikolai Ledentsov.
As mobile phone handsets continue to be the key driver behind growth in HB-LED manufacturing, Michael Hatcher reports from the Strategies in Light conference on a serious ramp-up of production capacity in Asia, "kilolumen" sources and the development of LED headlamps.
For Matsushita Electric Industrial, recordable DVD is set to be huge this year, while a next-generation DVD recorder based on a GaN laser is scheduled for July. Meanwhile, the company is refocusing its GaAs MMIC production on the global market. Bob Johnstone reports from company HQ in Kyoto.
Last year, Bookham Technology transferred one of the world's most advanced InP fabs from Ottawa, Canada, to Caswell, the former Marconi facility in the heart of the English countryside. Michael Hatcher visited Caswell to check up on Bookham's progress.
Martin Murtagh, Pat Kelly and Roy Blunt report on a novel approach to photoreflectance spectroscopy that measures both cavity-mode and quantum well transition energies, promising to improve the quality assurance of VCSEL epiwafers and reduce the need for destructive testing.
We've analyzed some of the emerging technologies and markets that will shape 2004, including recordable DVD, wireless LAN and wide-bandgap microelectronics. First, Michael Hatcher discusses the trends that will affect the overall compound semiconductor market.
Having carved out a niche in back-end processing of sapphire and SiC wafers over the past couple of years, some laser tool manufacturers are now targeting GaAs and InP wafers. Meanwhile, others believe that these material systems will remain the preserve of diamond scribe tools and saws.
As chip manufacturers continue to improve the performance and reduce the cost of their products, new applications in areas such as airport lighting and car headlamps continue to emerge. Tim Whitaker reports from the Intertech LEDs conference.
Growth in the high-brightness LED market will be fueled increasingly by illumination applications over the next five years as the price/performance characteristics of devices improve. Bob Steele of Strategies Unlimited analyzes the development of the solid-state lighting marketplace.
