CompoundSemi News Staff

April 10, 2006...EETimes gave out their Annual Creativity in Electronics (ACE)Awards at a dinner ceremony at the Fairmont Hotel in San Jose, California USA. Leo Mathew, the principal solid state engineer at Freescale Semiconductor, won the Innovator of the Year, for the invention of the inverted T-channel field-effect transistor (ITFET), which reportedly combines horizontal and vertical structures into a single transistor. According to EETimes, “The technology promises to extend progressive CMOS scaling to the 45-nanometer and finer process nodes.” The award for interconnect, passives and electromechanical products went to Avago Technologies and Lumileds Lighting for their Envisium Power PLCC-4 surface-mount LEDs . The Envisium Power PLCC4 was initially introduced before the semiconductor products group of Agilent Technologies became Avago. (Ref: Coverage). EETImes says that the Ultimate Product finalists were chosen by editors to be the most significant products introduced over the past 12 months. Winners were determined by a vote of EE Times and eeProductCenter readers.

TDK Ships 25GB Blu-ray Discs
CompoundSemi News Staff

April 10, 2006...TDK of Tokyo, Japan has begun shipping its 25 GB recordable and rewritable Blu-ray Discs. According to the company, the one-sided recordable media with about three times the capacity of conventional DVD’s is now being sent to retailers throughout the United States. TDK, a dominant company in digital recording solutions, says it is first to the market with bare Blu-ray Disc media. The company has set retail prices at $19.99 for a 25GB BD-R (recordable), $24.99 for a 25GB BD-RE (rewritable). TDK will reportedly also ship the 50GB Blu-ray Disc media later this year with retail pricing set at $47.99 for a 50GB BD-R (recordable) and $59.99 for a 50GB BD-RE (rewritable). While the 25 GB versions have a single layer, the 50 GB versions expected out later this year have a dual layer recording structure. After sending out mass production samples of the 25 GB media in December, the company issued the relevant license, and began mass production. TDK is offering a 50 spindle package of the recordable media for bulk configurations.

One of the technologies that the company says makes the media much more durable than other DVD’s is its hard coating called Durabis which the company claims increases scratch resistance by a factor of 100. In addition the coating reportedly resists fingerprints. TDK says the coating eliminates the need for the protective cartridge that was introduced with earlier prototypes of the Blu-ray discs. Along with the other benefitial properties TDK claimed for the technology, the Durabis coating rapidly discharges electricity, and resists the accumulation of dust.The media offers a 2X (72MBps) recording speed. The company has already created a quad layer 100GB prototype, and the company is working on producing the first 200GB prototype. TDK News Release

Gallium Arsenide Market Still Expected to Break $3 Billion in 2006
CompoundSemi News Staff

April 6, 2006...Compound Semiconductor market analysis company, Strategy Analytics of Boston, Massachusetts USA, has reiterated their prediction that the gallium arsenide (GaAs) market will break the $3 billion per year barrier in 2006. The company indicated that the market is in line with their previously released, long-term forecast report for the gallium arsenide market, which predicts a healthy 36% increase in total sales revenue for the industry from 2005 to 2010. The company sited the growth of the demand for multi-mode and multi-band cellular handsets for much of the increase. According to the report and their latest assertions this growth will help to offset the alternative service provider (ASP) erosion.

"It's not just a case of increasing handset shipments which helps to increase GaAs device demand from the handset market over the next five years," observed Asif Anwar, Director of the Strategy Analytics GaAs and Compound Semiconductor Technologies service. "2006 and beyond will see the market shift towards EDGE/GPRS-based and WCDMA/EDGE multi-mode, multi-band architectures. This will actually increase the number of HBT and pHEMT die going into increasingly complex RF front-end module solutions." Company News Release

Alan Thompson Previews Our SSLS 2006 Meet in Taiwan

April 4, 2006...Our senior technology editor (and industry guru), Alan Thompson, is again serving as the hardworking program chair for our annual gathering of solid state lighting suppliers. We've renamed the event, now in its 4th year, the Solid State Lighting Supplier's Forum (SSLS 2006). Anyone who's anyone in the CS/SSL suppliers community will be there. Dates are May 9-11 in Hsinchu. After reading Alan's preview of the SSLS 2006, which follows, we're sure you'll want to be there too. Don't forget to register now as we're expecting a bigger than ever turnout...JMcD

Preview of SSLS 2006
by Alan Thompson

The familiar Blue conference series continues in Taiwan with the same location as past years with a title change, to Solid State Lighting Supplier's Forum 2006 (or SSLS 2006) for short. The new title reflects the increasing emphasis on lighting becoming the major market for LEDs, although other applications remain important and will certainly be covered. The conference will again be held at the Ambassador Hotel in Hsinchu, starting with our morning pre-conference workshop on Tuesday, May 9th, 2006 and concluding at noon on May 11th in, thereby enabling many participants to catch planes that day). You can easily access complete details about the conference, including the registration, hotel reservations, sponsorship, and exhibition opportunities at the web site, www.ssls2006.com

The pre-conference workshop this year is designed to get things off on the right note by underscoring the most important job suppliers now need to tackle... that of meeting the needs of lighting designers. Just the concept itself of having a prestigious lighting designer (Jeffrey Miller, the director of external affairs for the International Association of Lighting Designers) as the one teaching the SSL industry suppliers, systems integrators and packagers about what the end customer wants and needs is noteworthy in itself. You'll surely want to hear what Jeff has to say about the real issues facing suppliers. Jeff's workshop will run about 2 hrs and will be priced at the modest range of about $200 per attendee.

Looking at the agenda we've put together...
Tuesday afternoon, the main event gets underway with a brief welcome by the conference co-chairs, Dr. Y.S. Liu of ITRI, George Mueller of Color Kinetics, and Dr. Robert Walker of eLite Optoelectronics. The first session will be kicked off by our first keynoter, Dr. Robert Steele of Strategies Unlimited, who will give his updated comprehensive overview of the supply and demand markets for HB-LEDs.

Bob Steele's update will be followed by Asif Anwar of Strategy Analytics who will cover the supply chain for the solid state lighting industry. Several speakers will then cover the activities in the major LED producing countries and the session will conclude with a panel discussion tackling the controversial question of who will emerge as winners in the race to capture market share. After close of sessions Tuesday, we've lined up a networking reception sponsored by Veeco, from 6 to 8p.

Wednesday morning, I'll open the sessions by moderating a panel looking at the prospects for significantly reducing the cost ($/lm) of LEDs. With several companies already reporting efficacies of 100 lm/W for white, we cannot expect more than a 2X cost reduction by improving efficiency to the theoretical maximum. Therefore the cost of the device must be reduced over the next decade by one to two orders of magnitude to address the general lighting market. Can this be achieved by current projections or will disruptive technologies be needed? Can we learn from the IC (Si) industry's successful reduction of cost/transistor by multiple orders of magnitude over the past 30 years? Join us and hear our industry luminaries sound off on this topic. From there, we'll then move on to technology updates for materials.

In the afternoon several talks, appropriately titled: "Show me the Money" will look closely at how our industry's growth could be further financed, ranging from venture capital, mergers and acquisitions, and internal growth. This promises to be an exciting and controversial topic, given the projected rapid growth, with new companies emerging, and mergers starting to take place, particularly in Taiwan. Two keynoters will be featured in this session: Richard Chen of Vincera Ventures and Peter Moran of Doll Capital Management.

Later In the afternoon we will again from our workshop instructor, Jeff Miller, who is on the board of the International Association of Lighting Designers (the folks who put on Lightfair). Jeff will capsulate what was detailed in the workshop and tell us all what the lighting people really need in order to incorporate LED solutions into their designs. We then move on to applications, covering backlighting, automobiles, and architectural. The session concludes with a keynote presentation by George Mueller of Color Kinetics, with what promises to be a dynamic and thought provoking talk by a pioneer of solid state lighting.

That evening's networking reception will be sponsored by Rubicon, followed by the Grand Banquet, sponsored by Aixtron. I want to take this opportunity to thank all our sponsors. While major sponsorships slots are now all booked (note their names and hotlinks to their corporate sites at the head of each conference page), our conference coordinator, Tom Griffiths, says there are more slots for Gold Sponsorships still open, which will appeal to those seeking to exhibit at SSLS 2006.

On the last final day, Thursday, May 11th, the conference will focus on the rapidly growing arena of high output LEDs and how problems such as heat dissipation and high optical flux can be mitigated through innovative chip design and packaging technologies. As you can see by scrolling down on the agenda page, we've lined up a great cast of key SSL industry suppliers to report, including Phil Kwan, VP of Philips Lumileds. We also have some surprises yet to announce, so... as Jo Ann always likes to say in this column space... stay tuned... as that agenda page gets updated in these final weeks of preparation. She'll be covering those "surprises" here, as soon as they can be made public.

As always, ample opportunity will be given for networking at the breaks and evening receptions, plus over 30 companies are expected to exhibit during the conference, showing their latest and greatest solutions. This year promises to be even bigger and better than Blue 2005, which was very successful, so make Hsinchu in May part of your travel plans.

We look forward to seeing you there!
