Zephyr launch fabrication & foundry services
ZEPHYR hopes to meet the growing demands of III-V semiconductor companies by offering its growth, fabrication, testing and production facilities. The company uses proprietary wide-temperature III-V VCSEL-based, optical technology, to bring rugged, high- performance optical interconnect solutions to demanding mission-critical applications. The firm is now also providing foundry services to the compound semiconductor industry. These include III-V MBE growth, compound semiconductor characterisation including photoluminescence, X-Ray diffraction, Hall-Effect, multispectral reflectivity, multispectral ellipsometry, and Surfscan. Zephyr is also offering optoelectronic component testing.
Zephyr Photonics CEO Tom Steding, states, “Our Semiconductor Fabrication and Foundry Services business unit was formed to match the growing demands of fabless semiconductor companies and semiconductor companies with our growth, fabrication, testing and production capabilities. Zephyr Photonics currently provides time-critical device development, testing and production services for a number of key industry customers.” Among Zephyrs’ unique resources is its
Toshiba launch GaN-on-silicon LED packages
TOSHIBA CORPORATION has started sales of white LED packages that are claimed to offer makers of general purpose and industrial LED lighting solutions a cost-competitive alternative to current LED packages. According to Toshiba, LED chips are typically produced on expensive 2- to 4-inch sapphire substrates. Toshiba and Bridgelux have developed a process for manufacturing GaN LEDs on 200mm silicon wafers, which Toshiba has brought to a new production line at Kaga Toshiba Electronics Corporation. This is a discrete products manufacturing facility in northern Japan. Deployment of Toshiba and Bridgelux’s new GaN-on-silicon technology to produce LED chips has
allowed Toshiba to replace sapphire substrates and to produce the chips on a much more cost-competitive silicon substrate. Going forward, Toshiba will promote product development and global sales toward securing a 10 percent share of the world market in 2016.
The LEDs, known as the TL1F1 series, operate at 1W and measure 6.4 mm x 5.0 mm x 1.35 mm. The light flux is 112 lm at
350mA.Planned production capability is 10,000,000 units per month.
10,000 square foot cleanroom in its Zephyr Cove facility, which includes a wide variety of growth, processing, testing, and production equipment. The facility is accredited by DMEA as the only U.S. Trusted optoelectronic foundry and IC supplier; and is ITAR compliant and ISO 9001:2008 certified. Zephyr Photonics’ team combines more than 100 years of relevant experience and works seamlessly with its customers.
“Zephyr Photonics is excited about this opportunity to play a key fabrication role in the semiconductor industry, enabling our customers’ innovation, and improving their time to market by leveraging our experience, in-depth knowledge, process libraries, IP and extensive facilities. Our customers couldn’t have been clearer, voicing their enthusiasm with our flexibility, responsiveness, time to market, and breadth of experience, which helps them to improve their own execution and downstream customer satisfaction. We believe our new business unit will grow to be a very important part of our overall corporate mission, to be a high- performance, specialised and trusted foundry partner,” concludes Tim McAllister, VP of Business Development.
Compound semiconductor
market slow DESPITE some revenue growth, the GaAs, GaN, SiC and SiGe markets are suffering at the expense of a stronger silicon market. With financial results in for the second calendar quarter of 2012, the compound semiconductor industry showed sequential revenue growth, but the industry is only slightly ahead of 2011 revenue performance. This is according to Strategy Analytics’ GaAs and Compound Semiconductor Technologies Service (GaAs) viewpoint, “Compound Semiconductor Industry Review July - September 2012: Microelectronics.”
While most of the companies highlighted in the report showed sequential revenue increases from the previous quarter, many are struggling in comparison to 2011 revenue. The result is an industry much closer to breakeven than substantive growth. The report also details several silicon-based product announcements for devices that are directly competitive to their compound semiconductor equivalents. “The positive news for the compound semiconductor industry is that most companies showed revenue growth for the quarter, making it the second consecutive quarter that the industry has seen growth”, notes Eric Higham, Director of the Strategy Analytics GaAs and Compound Semiconductor Technologies Service (GaAs).
“However, when you compare the results to 2011, the picture is not as clear. Using this comparison, many of these same companies are struggling to show growth and this reaffirms our position that 2012 will be a low-growth year for the industry”. Asif Anwar, Director, Strategy Analytics Strategic Technologies Practice adds, “Part of the issue is the strength of some of the silicon-based product solutions. We are seeing companies like Javelin and Amalfi Semiconductor, which is now part of RFMD along with Peregrine Semiconductor, release some very innovative products that are taking share away from the incumbent compound semiconductor devices”.
