Emcore Sells 49% GELcore Stake to GE; Names Nichia as GE's Strategic Partner
Jo Ann McDonald, founding editor

August 31, 2006...Breaking News... Speculation on "the street" earlier this week has been confirmed. General Electric Company (GE) has purchased Emcore's 49% of the GE/Emcore joint venture (JV), GELcore LLC of Cleveland, Ohio USA for $100 million. Concurrently, GE's Consumer & Industrial business unit inked a strategic alliance agreement with Nichia Corporation of Japan that this editor believes will result in Nichia's blue spectrum LED and phosphor technology expertise becoming the primary base technology ultimately fielded by GELcore into the budding solid state lighting (SSL) industry. (Ref: GE news release) The move now elevates GE to relatively equal ranks with its two major lighting company giant competitors, Osram of Germany, (which has always owned 100% of Osram Opto) and Royal Philips of the Netherlands, (which purchased all of Lumileds Lighting in San Jose last November. Ref: our coverage). Lumileds, now officially named Philips Lumileds, was originally a JV in which Philips and Agilent each owned equal shares. Osram Opto and Lumileds are blue spectrum (which includes white) LED chip makers, whereas GELcore has always purchased its starting LEDs from the outside, from various vendors. While some may call this announcement evidence of industry "consolidation," I see it as the lighting giants finally flexing their collective muscle, which spells nothing but good news for the entire SSL industry.

The founding head of GELcore in 1999 and then CEO of GE, Jack Welch, conceived of GELcore; Michael B. Petras, Jr. was named head of the JV. Michael is now VP for GE's electrical distribution and lighting. According to Michael, who has long been known to the compound semi community for his personal enthusiasm and strong support of solid state lighting, commented that "This agreement is a true win-win outcome for both parties and clearly demonstrates GE's commitment to solid state lighting technology. GE and Nichia's combined excellence creates a preeminent alliance that is ideally suited to support GELcore's efforts to accelerate the growth and penetration of LED-based lighting solutions in the $12 billion global lighting segment." Commenting on Nichia's stepped-up involvement with GE, Noboru Tazaki, executive VP and COO of Nichia added that, "This is a historic agreement when you consider that GE, a world leader in traditional lighting technology and LED systems and Nichia, a world leader in phosphor and optoelectronics technology are joining forces to advance LED technology and accelerate the penetration of LEDs into the general lighting industry." In the days ahead, I'll extend our coverage of this story in my next McDonald Report, adding opinions from various interested parties, but having personally been involved in the original conception of GELcore, I add the following initial perspective for our 2nd page LIGHTimes subscribers: Content continues for LIGHTimes SecondPage members...

Boeing Subsidiary, Spectrolab Awarded Contract for Solar Concentrator Cells
CompoundSemi News Staff

August 30, 2006...Boeing subsidiary, Spectrolab, has been awarded a 12-month contract to produce and deliver 600,000 solar concentrator cells to renewable energy company, SolFocus of Palo Alto, California USA.(Ref: Editorial Coverage). According to Boeing, the concentrator cells will be used to convert rays from the sun into usable electricity for consumers and businesses. Boeing says that the concentrator cells will be capable of generating more than 10 megawatts of power. This is estimated to be enough for 4,000 US homes. When the sunlight is concentrated, Boeing boasts that the average solar cell efficiency is above 35. Boeing points out that at this rate of efficiency, Spectrolab's concentrator photovoltaic cells can be more economical than electricity generated from conventional, flat panel photovoltaic systems.

Spectrolab will use multi-junction solar cells and light concentrating optics. Boeing contends that the cost of the mult-junction solar cells, which previously were used primarily in satellites, will be offset because fewer cells are required due to the use of the concentrators. In addition the improved efficiency, only a small fraction of the cell area is needed to generate the same power output of crystalline silicon or thin-film, flat-plate modules.

"Companies on the cutting edge of the renewable energy revolution come to us because we are the world's leading manufacturer of solar cells," said Charles Toups, vice president of engineering for Boeing Space and Intelligence Systems. "Our Spectrolab subsidiary has leveraged its expertise in space photovoltaic products to create solar cells with record-breaking efficiencies for Earth-based applications."

"Our mission is to deliver reliable solar-generated electricity at wholesale energy prices, and Spectrolab's multi-junction concentrator solar cells are key to making that possible," said Gary D. Conley, CEO of SolFocus. "Spectrolab's cells will be integrated into our upcoming solar concentrator field test program and then into the first phase of active deployments." Boeing News Release

August 30, 2006... II-VI and SemiSouth are not the only companies who have opened a new silicon carbide (SiC) production facility in recent weeks. Norstel of Norrköping, Sweden, officially opened its new facility on August 29. Thomas Östros, Swedish Minister for Industry and Trade and Mr. Mattias Ottosson, Chairman of the Municipal Executive Board in Norrköping, attended the Grand Opening of the 2000m2 (about 21,500 sq. ft.)facility.

According to the company, the construction of the plant began in February 2005. Norstel contends that the facility, which was designed and equipped with advanced infrastructure, process tools, and characterization equipment, is among the most technologically advanced sites focused strictly on producing single crystal SiC materials. The company also stated that the environmental impact is minimized through the use of sophisticated waste gas systems and in-house treatment of used process chemicals and waste water. All operations are strictly in accordance with the environmental permits granted by the Swedish authorities.

"We are now taking a major step towards establishing Norstel as a significant supplier of Silicon Carbide materials" said Dr. Asko Vehanen, CEO of Norstel. "Our technology is based on the patented High Temperature Chemical Vapor Deposition (HTCVD) technique. Making this method truly industrial will enable Norstel to produce high-quality large-diameter SiC crystals and wafers cost-efficiently, thereby opening new markets and applications."

Mitsubishi Electric Tops Japanese GaAs Device Makers, Strategy Analytics Says
CompoundSemi News Staff

August 28, 2006...Strategy Analytics (SA) revealed more details of their latest report about the GaAs device manufacturers. SA indicated that Mitsubishi Electric and Toshiba surpassed all other Japanese gallium arsenide (GaAs) device manufacturers in 2005. Eudyna Devices, Sony, and NEC fell from the top ten list in 2005, according to the company. Mitsubishi Electric was the market leader with significant growth in the MMIC business. At the same time the Mitsubishi Electric led supply of GaAs power amplifiers to the Japanese 3G handset market. North America had seven of the top ten GaAs device manufacturers from the usual manufacturers: RF Micro Devices, Skyworks, and Triquint. SA says that the usual list of GaAs device manufacturers were joined by fables company, Hittite. Hittite, RF Microdevices , Skyworks, and Triquint made up 52 percent of the GaAs device market in 2005. Notably absent from the top-ten list were any European device manufacturers.

"2006 will bring some changes as well. None of the European GaAs device manufacturers held a top ten position in 2005, yet we expect Filtronic to climb into this top ten GaAs device manufacturer ranking in 2006," predicted Asif Anwar, Director of the Strategy Analytics GaAs and Compound Semiconductor Technologies service. "The Asia-Pacific foundries will also maintain growth in 2006 and 2007. Demand for foundry services in some cases is actually coming from the traditional GaAs device companies themselves, many of whom are choosing to outsource excess GaAs device production rather than investing it in upgrading existing facilities."

"Despite these movements, we believe that North American players will continue to cement their dominance of the GaAs device market in 2006, since they supply the majority of GaAs devices to the strategically important handset market, as well as to other markets utilizing GaAs devices," maintains Stephen Entwistle, Vice President of the Strategic Technologies Practice at Strategy Analytics.

Commentary & Perspective...

BridgeLux Is Ideally Typical of Next Push in Solid State Lighting

August 30, 2006...The solid state lighting (SSL) industry is deeply rooted in the compound semi (CS) industry. If you haven't been around compound semi circles recently, you might think that SSL looks like the classic overnight success. Not so. Like so many of the compounds (GaAs for example), today's and tomorrow's GaN-based LEDs that are of the caliber truly robust enough to replace incandescents in general lighting applications are the result of over 20 years of collective work, rooted heavily in MOCVD, the manufacturing platforms that first came to light back in the mid-1980s. When hearing about the recent personnel additions to a USA/Asian company named BridgeLux (ref: Aug. 29 coverage), the significance of those roots came to light. The caliber of people now being recruited into the still-nascent SSL industry is very impressive.

BridgeLux (www.bridgelux.com) stands out as the ideally typical young USA company in the SSL field, full of veteran expertise. I think of BridgeLux as a leading indicator of the real progress going on deep inside the SSL industry. If you don't already know BridgeLux, they're a Northern California-based company that's moving forward especially quickly right now. The company was first established in 2003 as eLite Optoelectronics by former Emcore blue spectrum LED expert, Heng Liu who continues to serve as CTO. Then our longtime friend and colleague, Robert (Bob) Walker, also formerly from Emcore and the man who has served diligently as our perennial co-chair for our annual BLUE SSL Suppliers Forum in Taiwan, took over the CEO reins last year. They've been on a dramatic climb ever since. You can view bios and pictures of the senior management team on their website.

BridgeLux obviously knows what it takes to make truly SSL-worthy blue spectrum LEDs and they're proving high volume capability by already shipping millions of high-end InGaN LED chips per year into the SSL market out of their manufacturing facility in Taiwan. They currently have 25 people in residence at the Sunnyvale headquarters in the USA (i.e. "Silicon Valley), with 15 in Taiwan. Key people most recently added to the BridgeLux roster include Dave Bour as Chief Scientist, Gloria Fan as CFO, and Ghulam Hasain as a senior scientist. They join a cadre of other relative newcomers to the BridgeLux team that includes MOCVD-expert Jeff Ramer (also formerly of Emcore's R&D Lab) and Steve Lester, who made quite a name for himself in high power InGaN chip development while at Agilent (and before that, HP). The collective goal of this especially strong team is simple... to help enabling the SSL industry by getting the manufacturing costs of very high yield, truly SSL-worthy blue spectrum LEDs to an affordable and easily reproducible level.

The addition of Dave Bour as Chief Scientist should contribute significantly to achieving that goal. Dave's coming back to the compounds after a brief stint at Applied Materials (AMAT), hopefully bringing with him the silicon mindset that traditionally enables lower cost manufacturing. Dave, a GaN expert, originally hailed from Agilent, where he attained the prestigious honor of becoming an Agilent Fellow in 2000 (as well as being an IEEE Fellow). He's published over 200 articles and has 60 USA patents to his name. My hunch is that the resulting synergy of Dave plus Heng Liu, Jeff Ramer, Steve Lester and Ghulam Hasain will be something worth watching.

Many of us knew Steve Lester from his Agilent days, and others knew him from the University of Texas at Austin, earning his PhD in 1987. Ghulam Hasnain was formerly VP of advanced technology with LuxNet and brings over 20 years of experience in optoelectronics and holds several patents. Jeff Ramer and Heng Liu have strong industry histories, separately working at Emcore developing the original nitride reactors. To do that, they necessarily had to become superb nitride growers. Jeff, who helped teach our classic InP 101 video workshop at the 2001 Outlook conference (newly renamed CS Vision and totally a CS Online Inc. event now), proved at that he's an all-round compound semi MOCVD expert and a gifted grower. After Jeff went to Veeco with the sale of Emcore's TurboDisc division to Veeco, he worked on a new design of the GaN platform to achieve record uniformity for the critical InGaN active region, which dramatically improved the yield of LED devices.

With the team Bob Walker has now put together, we can expect to see noteworthy yield improvement out of BridgeLux that will help the entire SSL industry. And the addition of Gloria Fan basically represents the caliber of person we really want to attract to the SSL industry. She brings over 15 years management experience to BridgeLux, having served as VP of finance at UTStarcom, most recently serving as their VP of global business operations where she oversaw the company's IPO soon after that company scored the title of one of Business Week's 100 hot growth companies in 2002.

Why do I feel BridgeLux to be ideally typical of what's going on right now? Because they've either attracted especially talented people new to the SSL field, or they've enticed re-entries who originally made their mark in blue spectrum R&D. And that's the kind of talent it will take to get the manufacturing costs down where they need to be. The pattern is very much like what we've seen over the years at Cree: employing the best people in the field and concentrating on lowering costs and increasing yields. My hunch is that will require a more silicon-like manufacturing mindset to get there, which could explain why silicon pros are being attracted to the compound semi industry each day, especially as things stay rather tight in the overall tech sector. The prospects of being on the groundfloor of seeing InGaN LEDs take over first, compact florescents, then halogens, and eventually incandescent lighting applications, is the obvious lure.

Where BridgeLux goes, the SSL industry is likely to follow, and that directly benefits many throughout the CS supply chain. And we can't forget one other addition to the BridgeLux team, my friend Anita Draa, who served with Bob Walker when he ran Emcore's Pacific Rim sales team. Anita's now helping with BridgeLux marketing and herself holds a Ph.D. in chemistry. Now that's my kind of "Marcom" (marketing communication) expert! She understands all levels of the challenge. A lot of those MOCVD platforms out there were originally sold by Bob and Anita. And many more were perfected by the steady and excellent work of Jeff Ramer and Heng Liu. As to what's specifically going on behind the scenes at BridgeLux, and why they're able to attract such high caliber people, all I can say is... Stay Tuned.
