Veeco Projects Growth and Announces Status of Corrective Actions
Scott McMahan
March 17, 2005...In a quarterly conference call Edward H. Braun, chairman and CEO of Veeco said that they should have about a two percent increase in revenue per quarter over the next three quarters despite the likely decline in the LED and wireless equipment sales resulting from market saturation in 2005. Mr. Braun reported, “Revenues increased in all our core markets, with particular strength in LED, wireless, data storage and semiconductor.” Mr Braun added, “Our 2005 focus is to improve our profitability across our Process Equipment and Metrology product lines and to position Veeco for what we currently believe are strong growth opportunities in 2006 and beyond.”
Veeco announced their completion of the internal investigation of improper accounting at their TurboDisc business unit. Jeferson Wells, a firm retained by Veeco’s audit committee, reported the findings. According to Veeco, “Conclusions reached during the investigation included that the improper entries were made by a single individual at TurboDisc whose employment had been terminated prior to the commencement of the investigation.” The company said that the investigation, that began after an internal audit found improper accounting, focused on, “the value of inventory, accounts payable and certain liabilities, as well as certain revenue transactions of TurboDisc.” Mr Braun added, “Actions have been taken to resolve these accounting issues, including the completion of an independent review, appropriate staffing changes, and transitioning TurboDisc to Veeco's SAP accounting system."
He said, that they expanded the investigation into, “other parts of the company in certain areas just as a precaution and found nothing to warrant any further examination or expansion of the search.” Mr. Braun explained, “Its only limited to one individual, and one site, and he is very much contained…No motive was found; there was no provable embezzlement. No assets left the building. Nobody seems to have individually prospered because of this. No one was coerced by management or the company to follow this incorrect accounting. We have found the problem, we have fixed the problem.”
In related news, Veeco appointed Richard Wissenbach as Senior Vice President, General Manager for its Compound Semiconductor/Epitaxial Process Equipment Group, which includes the TurboDisc MOCVD operation in Somerset, New Jersey USA and its MBE operations in St. Paul, Minnesota.

Agenda Set for BLUE 2005 in Taiwan
March 22, 2005...After burning the midnight oil more days than they likely want to count, our co-chair for BLUE 2005, Dr. Robert (Bob) Walker and his associates at YEBY, and our President and CEO here at CompoundSemi Online, Tom Griffiths have hammered out a great agenda for the upcoming May 16-18, 3rd Annual BLUE 2005 meet in Hsinchu, Taiwan. It wasn't easy fitting everyone in, but the speaker lineup even tops last year's event which was held at the same venue in Taiwan. In just three short years, BLUE has become a very popular and inviting event for speakers.
This marks the second year for BLUE in Taiwan (it began in 2003 in Dallas, Texas USA) and this time around, we expect a sellout crowd. So before you do anything else, scroll through the agenda, mark your calendars MAY 16-18 !!), and make your travel plans by simply clicking on "location & hotel" at the top of www.blue2005.com for details. Thanks to the magic of the web and the unobtrusive strength of our industry portal, SolidStateLighting.net, it's never been as easy as it now is to stay connected to everyone who's anybody in the rapidly growing international SSL industry, in real time.
So what's in store for conference attendees at BLUE 2005? Not only another great lineup of SSL industry experts as speakers, but the opportunities for making the informal business connections that mark our CompoundSemi Online, Inc. events. The first get-together is Monday evening with the Networking and Welcome Reception sponsored by Aixtron. The following morning on Tuesday, May 17th, the conference gets underway beginning with a welcome by our trio of co-chairs, Dr. Yung-Sheng Liu, VP and General Director of OES at Taiwan's ITRI, Dr. Tae-Il Kim, President of the Korean Photonic Technology Institute, and Dr. Robert Walker, Principal of YEBY Associates.
Keynote speaker for Tuesday morning is the foremost market researcher in the fields of HB-LEDs and GaN based devices, Dr. Robert Steele, Director of Optoelectronics Practice at Strategies Unlimited. Bob will bring to Taiwan the latest LED market numbers. Since his team at SU is just finishing up their 4th edition of their acclaimed GaN technology and application review, the information the information Bob will share will be especially fresh, timely, and insightful. This 500 page comprehensive study, which will be off to the printer shortly, is titled Gallium Nitride 2005 - Technology Status, Applications, and Market Forecast. SU has been issuing their GaN study since '97, which is updated every other year. The SU team has conducted extensive interviews all over the world for this report. Virtually all blue spectrum LED and LD related companies as well as GaN-based electronic sector depend heavily on its contents. Details on ordering can be found by clicking here. In addition, Bob will also focus on high power LEDs, developments in phosphors, and the next wave of LED applications. Miss Wu Ling, Director of China National SSL Program will discuss China's HB-LED industry and their National Solid-State Lighting Program in one of Tuesday morning's highly anticipated presentations.
After a full morning of presentations and discussion that review initiatives from around the world, with special emphasis on Asia, the next major networking opportunity will be Tuesday lunch, sponsored by Accent Optical Technologies. Tuesday afternoon presenters will emphasize new application opportunities. The speakers will include Dr. S. H. Chan, Chairman & CEO of AOT of Taiwan, addressing the Cellphone and SMD markets and Volker Haerl, Director of R&D at Osram Opto, who will speak about penetrating the automotive market. Rounding out the afternoon presenters, Professor Tsunemasa Taguchi of Yamaguchi University in Japan, will report on Japan's progress in their White LED Lighting Program.
Tuesday comes to an exciting climax beginning with the 4pm keynote talk by George Mueller, Chairman and CEO of Color Kinetics (CK), the USA pioneer of intelligent LED illumination technologies. CK is a publicly held company, trading on the Nasdaq exchange. CK's annual report was filed March 10th with the Securities & Exchange Commission, and reading it reveals to newcomers to our business precisely what the HB-LED supply chain (which makes up the prime attendance at BLUE) is helping create. The title of George's talk is Lighting the Night -- It's All About Control and Intelligence. Then it's on to the Tuesday evening banquet, sponsored by our premier diamond sponsor, Veeco.
Wednesday, May 18th and the final day of BLUE 2005 is another jam packed day full of excellent talks and discussions highlighted by two keynote addresses. The morning keynote will be delivered by H.S. Chung, Senior Executive VP, Dongbu Anam of Semiconductor Inc. of Korea, and Former General Manager of Samung/SEMCO speaking from the Korean manufacturer's perspective. Our Wednesday lunch is sponsored by BOC Edwards. The afternoon keynote talk during a special IP section, which is a new addition to this year's BLUE event, will be delivered by Patricia A. Martone, a Partner at the USA Fish & Neave IP Group of the Ropes & Gray LLP law firm. A experienced specialist in IP issues, Pat's talk is titled Intellectual Property in the HB-LED Industry: Lessons from history in other semiconductor markets.
BLUE 2005 will build from concerns expressed by speakers and attendees at last year's BLUE 2004 meet, which is why we added the IP session. Several such key issues as predicted would come true by keynote and featured speakers last year did indeed "come true". Why? Because BLUE is a gathering of the true production leaders of blue spectrum LEDs and laser diodes. The producers of the key substrates, epiwafers, devices, and packaging technologies, coupled with the innovators that enrich those production lines, are what make this industry what it is today, and they're at the epicenter of what it's destined to be in the near and far term future.
According to Strategies Unlimited, blue, green, and white LED technology (which together form the "blue spectrum" and thus the name for this popular event) has continued its large-scale commercial growth resulting in revenues exceeding $3 billion in 2004. White LEDs, which are rapidly replacing conventional light sources with solid state lighting solutions, are responsible for over 50% of the total GaN related LED market. The shakers and movers of this market will all be attending BLUE 2005. Shouldn't you plan to be there too? Registration is now open, but trust me... it's likely to be a sellout, so register early and be guaranteed a seat at the table.
