IBM and MediaTek to Collaborate on Wireless 100x as Fast as Wi-Fi
CompoundSemi News Staff

October 22, 2007...IBM and MediaTek announced a joint project to develop millimeter wave technology that could wirelessly transmit a full-length high definition movie to and from a home PC, hand-held device, retail kiosk, or television set in seconds. The companies will integrate IBM's new mmWave radio chips, antenna, and package technology with MediaTek's expertise in digital baseband and video processing chips. IBM and MediaTek boasted that it would allow the transmission of a full-length high definition movie almost as fast as clicking the remote control. According to IBM, data transmission in the mmWave frequency band could be at least 100 times faster than current Wi-Fi standards. IBM gives the example of a 10 Gigabit file being transmitted in a mere 5 seconds compared to ten minutes with current Wi-Fi standards. Such a device would open up a wide range of multimedia possibilities.

IBM Research demonstrated a dime-sized prototype packaged chipset made from its 0.13-micron silicon germanium BiCMOS process to wirelessly transmit uncompressed HD Video in February 2006. "This collaborative effort will enable consumers to wirelessly transfer large multimedia data files around their home and/or offices in seconds," said Dr. T.C. Chen, vice president, Science & Technology, IBM Research. "This will enable a world where you can have your entertainment when you want and where you want it." IBM News Release

CompoundSemi News Staff

October 22, 2007...The photovoltaic company, Heliovolt, announced that it has raised a total of $101 million in Series B funding. Just days after the Austin City Council voted to approve an abatement of 60 percent of property taxes over ten years if Heliovolt sets up a manufacturing facility there, Heliovolt announced a $24 million increase in series B funding. The council hopes the incentive will put Austin on the top of the list of potential locations for its photovoltaic production facility, according to an article in the Austin American Statesman. Although the choice is not official, based on the timing of the funding announcement, the incentive package from Austin, Texas may have worked. The company was also recently distinguished as an AlwaysOn GoingGreen Top 100 company.

The funding was raised with investments from Sequel Venture Partners, Noventi Ventures, and Passport Capital. Heliovolt says that the additional funding will be used to more quickly scale-up and globally deploy the company’s proprietary manufacturing process for CIGS building-integrated solar products. Ron Bernal, General Partner with Sequel Venture Partners commented, “From an investment perspective, HelioVolt’s FASST manufacturing process embodies the most attractive technological and economic characteristics within the CIGS category, as well as the broader solar landscape.

US Air Force Increases Funding for Tandem CIGS Photovoltaics at Ascent Solar
CompoundSemi News Staff

October 17, 2007...Ascent Solar Technologies, Inc. (Ascent Solar) of Littleton, Colorado USA, a developer of thin-film copper indium gallium selenide (CIGS) photovoltaics, announced that the US Air Force Research Laboratory (AFRL) has increased funding for its development of high-performance thin-film tandem photovoltaics (PV). The contract modification adds up to $749,000 over a 27-month period. Tandem solar cells are solar cells in a stack in which the top one collects only the blue light of the spectrum, and the bottom collects the remaining portion of the spectrum. Since 1995, AFRL funded the development of flexible CIGS at ITN Energy Systems. Now, it continues the funding the technology development, but at Ascent Solar.

Since 1995, AFRL has provided funding for the development of the flexible CIGS at ITN Energy Systems, Inc. Now AFRL funds the research at Ascent Solar, including the development of aspects of future tandem devices. Experts expect that the tandem solar cell approach combined with CIGS technology will reach 20% efficiency in the future. Ascent Solar Chief Technical Officer Dr. Joseph Armstrong stated, “...In terrestrial and building integrated photovoltaic (BIPV) applications, such as roofing tiles and building facades that operate at elevated temperatures, future tandem devices can provide a significant advantage over existing thin film by delivering more power in less area.” Ascent Solar News Release

Rohm Increases Emission Wavelength of Nonpolar Laser Diode to 463 nm

October 17, 2007...Rohm Co. Ltd. demonstrated its blue nonpolar GaN-based laser diode. The company was able to increase the emission wavelength of the laser that uses the nonpolar plane of GaN crystal to 463nm, measured during pulse oscillation, according to an article in Nikkei Electronics. The wavelength is reportedly the longest for a nonpolar GaN laser diode.

The article pointed out that only recently a research group from Rohm and Tohoku University reported the increased wavelength of 452nm. Rohm also succeeded in reducing the threshold current to 41 mA or roughly 1/3 of the 130 mA current required for the 452 nm wavelength, the Nikkei Electronics article said.

Cree Announces Commercialization of 100-mm Zero Micropipe SiC Substrates
CompoundSemi News Staff

October 15, 2007...Cree of Durham, North Carolina USA, announced the commercial production release of its 100-mm Zero Micropipe (ZMP), n-type silicon carbide (SiC) substrates. The commercialization is the result of a project that was partially funded by the U.S. Army and the Defense Advanced Research Projects Agency (DARPA). SiC can be used in power, light, and communications components, such as power-switching devices, light-emitting diodes (LEDs), and RF power transistors for wireless communications. Cree first demonstrated the 100-mm version of its Zero Micropipe substrates in late may 2007.(Ref: Coverage).

Cree named the SiC substrate product Zero Micropipe because the company says it virtually eliminates micropipes, a common crystalline defect in SiC. Micropipes can decrease overall device performance, reduce reliability, and can decrease the number of usable electronic devices per wafer. In late May, Cengiz Balkas, Ph.D., Cree vice president and general manager for materials stated, “...We expect that ZMP technology can significantly improve device yields, expand the range of products that can be designed and produced, and enable manufacturing at higher-volume levels than had been possible before.” (Ref: May 23, News Release). In the most recent announcement Balkas stated, “The integration of this technology across other Cree product lines is expected to accelerate the adoption of SiC as a high-volume, production-ready material platform.” Company News Release

Commentary & Perspective...

Sensory Overload
Jo Ann McDonald, founding editor

October 17, 2007...Those who travel extensively know all about the multitude of mixed signals that scream at you in airports and other public gathering places. But those of us who play hermit in labs or other quiet dwelling places sometimes experience a significant culture shock when we actually see all the end products our compound semi and solid state lighting industry marvels have made possible. To the sheltered few, seeing them at work can result in an absolute state of sensory overload!

As one among the semi-retired, I purposely don't get out much anymore. In my case, I spend the vast majority of my time at my ranch in Central Texas tending to our longhorn steers, native wildlife, and other ranch critters, logging onto my laptop only when I need to check email or write this weekly McDonald Report column. In 2003, like so many others, I vowed never to fly anywhere again, but broke that promise this summer with a trip to Minneapolis for a family reunion and again last week for a flight to the San Francisco airport, via DFW, to attend my 50th high school reunion in Burlingame, California (class of 1957). With all the downtime they require in the airports these days, I had plenty of time to catch up with what's been going on in the "outside world." Even though I routine track the world's most leading edge advanced technologies (i.e. compound semi-based), in my opinion, the experience was truly mind-boggling.

I got to see iPods and iPhones at work, flat screens I never dreamed were so large, clear and vivid (and loud plus unnecessarily cluttered), cellphones glued to a variety of ears, earpieces that made people look like the old White House secret service guys and everyone in a hurry... but reasonably cheerful. Behind the scenes at the airport was probably the most impressive. The technologies that do the security scanning are fast and efficient, I found the security people competent and friendly, and the Skyrail at DFW truly fast, though I got kinda tired of the same droid voice over and over again. Not that I want to repeat it, but all in all, it was a surprisingly uplifting experience.

What were pervasive were the handheld devices our tech world has helped make possible. They are, of course, marvelous and varied. But in my opinion, they've created somewhat of a backlash. Although most people have become absolute pros at multitasking, they're a bit overly dependent on them and certainly not concentrating on what should, perhaps, be foremost in the concentration realm. Like driving. I saw a number of unbelievably stupid blunders being committed by people behind the driver's wheel that could have been avoided if they'd had both hands on the wheel and eyes on the road instead of talking on their phones or text-messaging or making entries in their digital diaries. We used to think the woman putting on makeup while driving was the biggest hazard. That's nothing compared to what's now going on.

The flat screens our tech world has helped create are marvelous. If you're scouting for the latest best product, you don't have to look any further than your nearest airport. I was really impressed by the overall quality, but totally unimpressed by the content. How can anyone possibly track all the clutter CNN puts out in the constant scrolls, and how can anyone take real news seriously when FOX news is screaming constant hysteria? "Panic Central 5" should be the name of the local news source. When I was in Minneapolis in June, I arrived the day after the big bridge collapse. One of my cousins lived 3 doors down from the bridge and we toured the scene with me pointing out the insanity of the television media. Sure enough, Bambi was putting on makeup, giggling and carousing with the crew, and then when the lights and action came on, she changed to her "totally sincere look" interviewing families of the victims. In another clutch, the current governor of Minnesota was being interviewed, talking in a most distraught manner, but another cousin, who was the COO for ex-governer Jesse Ventura, shared with us that the current governor was the one who vetoed spending for bridge improvements and upgrades. Hypocrisy reigns supreme out there, and we're all smarter if we remember that.

I got an absolute kick out of the plethora of shops and restaurants that are now in some airports. Minneapolis and Dallas-Ft. Worth are the most impressive; San Francisco the dregs (where you're lucky to find a hamburger). In Minneapolis, there's an Ike's restaurant (the best!), a Harley-Davidson Shop and a Cashmere Shop (I stopped to pet the cashmere, a pair of cashmere socks costing only $65). Much fun. In DFW, there's a sign that said it all: "The Malls Are Getting Jealous". But don't plan on shopping at SFO unless it's for the most expensive water ever, and a bit of SF sourdough bread, or See's and Ghiradelli chocolates.

In Northern California, due largely to the tech downturn that evidently continues for many, I discovered some interesting facts from fellow travelers and those I met up with at the reunion. In contrast to though who are still un- or under-employed, Google employees are doing great, so the Silicon Valley dream of becoming an overnight millionaire still exists. According the mother of a new Google employee, there are a number of millionaires at that spectacular company who are under 30, and her daughter, who lives in downtown San Francisco, has a Google-owned bus that comes to drive the SF employees the half hour plus to work. Very cool. So keep on dreaming and working hard. Maybe your company too will hit it big one of these days.

In my old hometown of Burlingame, I was pleasantly surprised to see that that particular SF bedroom community hasn't changed a bit, except for the better. It's the most lively, vibrant, upscale village anyone has ever had the pleasure of visiting, let lone living in. And despite the local government trying to get rid of the hazardous eucalyptus trees that are unique to Burlingame (nonnative with shallow roots that can easily topple in high winds--fortunately there aren't many high winds there), they still reign supreme, majestically setting that town apart from all others that string up and down The Peninsula. While many may fly into SFO, which is actually on the border of Burlingame and Millbrae, and stay in one of the many hotels near the airport, few travelers actually venture west across the highway, (toward the ocean) to downtown Burlingame. If you ever get time, do so. It's well worth the effort. There's literally... Nowhere Else But Burlingame.

As for the reunion itself, for those of us still alive (we're all about 68 now), collectively we looked great! It was such a pleasure to hear the stories of successful careers as lawyers, engineers and other professionals, and even more pleasurable to see pictures of everyone's grandchildren. It's those grandchildren I think about now that I'm safely back to my hermit lifestyle. Will there be so many humans on earth that they'll have a tough time repeating our success track? Will the environment be able to sustain the increased population?

I was greatly encouraged to hear that, while I was gone, on October 12 this year's Nobel Peace Prize is to be shared, in two equal parts, between the Intergovernmental Panel on Climate Change (IPCC) and former USA Vice President Albert Arnold (Al) Gore Jr. "For their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change." What this means to me and to the compound semi and solid state lighting industries we champion in these pages, is that the technologies we create, especially advanced solar cells and LEDs, now have a real chance of catching on. And if they enjoy as extensive an installed base as our handheld devices and flat screen TVs, well... our grandkids just might have a chance of thriving the way we've thrived these last 50 years. So keep up the great work!
