Funding Awarded for Carbon Nanotube Manufacturing System Commercialization
CompoundSemi News Staff

June 5, 2006...The Advanced Technology Institute (ATI) at the University of Surrey, and its partner for plasma processing, a deposition system maker, CEVP, have won project funding to develop a tool to grow nanomaterials. The funding infusion from South East England Development Agency (SEEDA) of £215,000 increases the total project development capital to £450,000. The program’s goal is to commercialize a device for mass producing carbon nanotube technology. The organization says that it has created a promising prototype called NanoGrowth which it hopes to develop into a “turnkey” tool for manufacturing highly bespoke nanomaterials on 3-inch substrates. ATI hopes the tool will eventually scale up to 12-inch substrates.

Chemical vapor disposition (CVD) requires temperatures above 700 degrees Celsius to grow carbon nanotubes. NanoGrowth however, uses a plasma enhanced system that allows significantly lower processing temperatures. ATI says that mass production opens the door to a wide range of possible products and applications. In addition to selling the NanoGrowth machine itself, the University and CEVP hope to develop some carbon nanotube-based products. "SEEDA funding will help us transform the prototype NanoGrowth machine into a world-beating technology platform for nanomaterials," said Professor Ravi Silva, lead investigator at the Advanced Technology Institute. "We are already talking with multinationals about a range of high-tech products, and as well as developing the tool, we are actively examining routes to create a spin-out vehicle for this exciting technology." The Advanced Technology Institute expects the benefits of the research and development project to extend to compound semiconductors, solid-state lighting, and high-efficiency solar cells.

Presenters will discuss the latest advances in LCD displays, backlighting, plasma displays, and organic light-emitting diode displays. Among the companies we regularly cover: MOCVD equipment maker Aixtron, optical component company, Bookham, optical component maker and test and measurement company, JDSU, micro-display pioneer Kopin, and lighting company, Osram Sylvania will be exhibiting. (Ref: SID web site). According to SID, the conference will have 250 exhibitors and a record 540 total papers-including 61 Invited Papers and 14 Distinguished Papers-will presented over four days by the top display experts in the world. These will reportedly examine the entire gamut of the industry's hottest topics. In what some industry watchers consider a sign of the switch to a new technology, cold cathode fluorescent lamps (CCFLs) are not on the agenda. Not surprisingly, LED backlighting will be among the presented topics. (Ref: SID web site).

TDI Hopes to Open the Door to More GaN Devices
CompoundSemi News Staff

June 5, 2006...Technology and Devices International Inc.(TDI) of Silver Spring, Maryland USA, hopes to fill the industry’s need for 4–inch substrates which have a high-latice and thermal match with gallium nitride (GaN). TDI has reported fabricating substrates of 4-inch diameter with a layer of aluminum nitride (AlN) on silicon carbide (SiC). The company says these substrates are ideal for group III materials. The group-III nitride compound semiconductor material family includes gallium nitride (GaN), aluminum nitride (AlN), indium nitride (InN) and their alloys TDI’s new product is aimed at substrate applications for ultra high power AlGaN/GaN devices such as high electron mobility transistors (HEMTs) and high frequency power amplifiers for next generation of wireless communications. Other possible applications include high power blue and ultra violet (UV) light emitters, light emitting diodes (LEDs) and laser diodes (LDs). According to the company, the product prototype consists of 10 microns thick of single crystal AlN film deposited on a 4-inch SiC wafer. The company points out that the substrates provide both the unique thermal conductivity of SiC and the exceptionally high intrinsic electrical resistivity of AlN.

“Development of 4-inch semi insulating substrates for high power GaN-based HEMTs has a long history and we are pleased to inform nitride community and especially our customers that the first prototype of AlN-based 4-inch substrate has been fabricated. The prototype was fabricated using proprietary stress control technology and crystal growth equipment developed by TDI for deposition of thick crack free AlN films,” stated Vladimir Dmitriev, President and CEO of TDI. He added, “Our customers have been asking about 4-inch substrates from the very introduction of the first 2-inch AlN-on-SiC wafers three years ago followed by 3-inch product introduction a year ago. This new product will allow our customers to use existing 4-inch device manufacturing lines, reduce production cost and speed up commercialization of GaN devices. We plan to start pilot production of 4-inch AlN-based substrates in a few months and make the first product shipments in the last quarter of 2006.” Company News Release

CompoundSemi News Staff

June 1, 2006...Global Communication Semiconductors, Inc. (GCS), a compound semiconductor foundry in Torrance, California USA, will begin offering its proprietary high linearity HFET foundry process to address the high dynamic range requirement of base station driver amplifiers. "GCS has a number of proprietary FET technologies including 0.5um and 0.25um PHEMT processes. Our 0.5um high performance HFET process is the latest addition to the FET family. With a breakdown voltage of 16V with a pinch off voltage of -2.0V, this technology was developed specifically with high linearity in mind and it is ideal for linear amplifiers that require high dynamic range," commented Jerry Curtis, CEO of GCS. "As a performance example at 2.0 GHz, when biased at 8V and 50% Idss, our 1.2mm HFET device can achieve an output power of 28.1 dBm with a Third Order Intercept (TOI) point of 48.5 dBm. With a 20.4 dB linear figure of merit, a difference between TOI and P1dB, our HFET is by far one of the most linear foundry processes ever available. Similar linear performance can also be achieved at 5.0V bias. The superior linearity makes it well suited for use in both analog and digital wireless communication infrastructure and subscriber equipment including 3G, cellular, PCS and fixed wireless system," continued Mr. Curtis.

Hot Markets: WiMax, Warm Whites & "lexel"

June 1, 2006...WiMax apps appear to be driving the compound semi (CS) communications sector these days, while warm white light and "lexel" technology appear to be catching on in the fledging field of solid state lighting (SSL). The only thing down this month are the price tags of USA publicly held stocks. Along with virtually all their big brother stocks in the overall tech sector, the model CS/SSL stock portfolio dipped in May from a healthy November to April run-up.

My CS/SSL model stock portfolio now includes 14 companies representative of the fields we cover in these pages. Virtually all stocks traded over USA exchanges dropped from 3 to 7% during the last month. In late March, my model CS/SSL stock portfolio was hitting remarkable heights of a 60% rise in value (ref: March 20th McD Report... but it's hard to pick "the benchmark", given the bubble-burst from the point where many of them were trading in double digits six years ago and are trading at single digits now). The last few days have seen an upturn, so maybe it's going to be one of those exciting summers.

Macroeconomics aside, the star performer in the portfolio remains the steadfast and relentless Cree (Nasdaq symbol, "CREE"), which continues to perform as my poster-child company by leading in both the CS and SSL industries. But does the company's stock performance reflect the real story of Cree's progress and contributions? Far from it. Cree was one of the first I selected when forming the model portfolio one year ago because it's one of my all-time favorite companies. Buying in a year ago at what I thought was a reasonably low of $25/share. (At least compared to the triple-digit peak of the bubble). By mid April, the price had made a 6-month run from 25 to 35 and then promptly plopped back to 25. The (hopefully short-lived) panic made for some attractive buying opportunities for those that believe. Would that I could afford more than the representative 100 shares...

It's important to keep in mind that the drop was totally unrelated to the company's performance as Cree continues to be a top contributor in all their wide bandgap (WBG) substrate and device pursuits. Take their strides in the WiMAX space, for example, which is turning out to the hot app area currently driving excitement in the nitride/electronics community. The WiMAX standard is playing a major role in a movie that could be titled The Unwired World: Part 3, featuring cellphones, wireless LAN in the house/coffee shop, next wireless (real, 1+Mbit) Internet Everywhere. Without much excitement happening in the telecom stocks, too many trade publications have paid such sparse attention to WiMAX that I actually had to go back and look up what it stands for, and who's driving what. Cree's recent release of a new GaN HEMT power amp for WiMAX transistor options was the wake up call. Ref: Cree news release and our coverage.

WiMAX stands for World Interoperability for Microwave Access, Inc. The lower case "i" is clever, but then everyone's playing with combos in lower case as editors boycott anything in all caps. According to the WiMax Forum website, www.wimaxforum.org, WiMAX is a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL, providing fixed, nomadic, portable and, eventually, mobile wireless broadband connectivity without the need for direct line-of-sight with a base station. WiMAX technology will be incorporated in notebook computers and PDAs by 2007, allowing for urban areas and cities to become “metro zones” for portable outdoor broadband wireless access. It's obviously, the wave of the future.

The hot area in the SSL side of our reporting right now is the overall field of "warm white" LEDs. North Carolina SSL startup (and Cree spinout) LED Light Fixtures Inc. (LLF) is the latest to report significant warm white breakthroughs this week at Lightfair International (ref: news release). The question some have is: Are we correctly, or mistakenly making warm whites an interim holy grail? The incandescent in your closet still can't help you see black vs. dark blue socks. And natural sunlight is still the preferred hue for humans. Maybe we should be talking up "the full spectrum future" where we deliver better light, hue-keyed on different phases of sunlight rather than just more lumens per watt. I get the feeling that's what TIR's "lexel" technology is all about, and that they're trying to form a WiMAX-like standard for the SSL industry with lexel.

TIR made quite a splash at Lightfair this week with the official branding of lexel, which could indeed prove to be a linchpin SSL integration technology (ref: coverage). TIR is slowly honing their message about lexel but they're pulling the media's chain by spelling it in all lower case. If their intent is to indeed establish a WiMAX-like standard, I'd have branded it LeXel or leXel. (Not too late to change, TIR! The evolution would make a good story.) In my book they made a major error by affixing the trademark-applied-for symbol of "TM" to their wire releases. (FYI... the "TM" means the trademark has not-yet- been issued by the USPTO. Following said issue, the company gets to affix the classic "R" with a circle around it. Try and dupe that on the wire services!) The trademarks symbols are for spec sheets and ads, but they matter not to the press. Editors just delete them. Take a look at a typical wire service, (ref: Yahoo) and you'll see what I mean.

That aside, thanks to "lexel," TIR Systems is finally being added to my model stock portfolio. I've tracked TIR since it was a startup which was during the early days of commercial compound semiconductors. Originally listed on the old Vancouver Stock Exchange back in the 1980s, TIR became formally listed on the Toronto Stock Exchange (TSX) in 2004. As publically disclosed way back in October I think TIR will do especially well thanks to their lexel technology. TIR.TO aka TSX: TIR was trading at close of day yesterday at $1.26 (Canadian dollars), down from a year high of $2.15. In 2004 it went public and traded at about $6. Beyond Cree & TIR, the other 12 stocks in the portfolio look to have turned up from the May slip, perhaps on the speculation that the new US Treasury Secretary, Hank Paulson, CEO of Goldman Sachs (ref: Fortune mag Jun 1 article for a fun profile) might push back on that growing government spending that tends to give markets the jitters. All these stocks are traded on the USA's Nasdaq exchange and include: ANAD (Anadigics), AIXG (Aixtron), AXTI (AXT), CLRK (Color Kinetics), EMKR (Emcore), JDSU (JDS Uniphase), KOPN (Kopin), RFMD (RF Micro Devices), SPIR (Spire), TQNT (TriQuint), WJCI (WJ Communications), and VTSS (Vitesse). As usual, with all these, I'm in for the longhaul, and I try my best to tell readers at least 30 days ahead of time if I'm adding or deleting from the list before actually doing so (like my commentaries would actually change anything, but hey... you never know). Let's expect growth as people continue to catch on to what our technologies really mean.
